For when they are again asked what it is that has altered the pneuma, they will only be able to reply, “the abnormal heat,” and particularly if it be the pneuma in the food canal which is in question (since this does not come in any way near the bubo). Yet why do I mention those animals in which the property of the pneuma plays an important part, when it is possible to base one's argument upon human beings, in whom it is either of no importance at all, or acts quite faintly and feebly? But Erasistratus himself agrees that human beings digest badly in fevers, adding as the cause that the activity of the stomach has been impaired. He cannot, however, advance any other cause of this impairment than abnormal heat. But if it is not by accident that the abnormal heat impairs this activity, but by virtue of its own essence and power, then this abnormal heat must belong to the primary diseases. But, indeed, if disproportion of heat belongs to the primary diseases, it cannot but be that a proportionate blending [eucrasia] of the qualities produces the normal activity. For a disproportionate blend [dyscrasia] can only become a cause of the primary diseases through derangement of the eucrasia.

καίτοι τί τῶν ζῴων ἐκείνων, ἐν οἷς ἡ τοῦ πνεύματος ἰδιότης μέγα δύναται, μνημονεύω, παρὸν ἐπʼ ἀνθρώποις, ἐν οἷς ἢ οὐδὲν ἢ παντάπασιν ἀμυδρόν τι καὶ μικρὸν ὠφελεῖ, ποιεῖσθαι τὸν λόγον; ἀλλʼ ὅτι μὲν ἐν τοῖς πυρετοῖς οὗτοι κακῶς πέττουσιν, ὁμολογεῖ καὶ αὐτὸς καὶ τήν γʼ αἰτίαν προστιθεὶς βεβλάφθαι φησὶ τῆς γαστρὸς τὴν ἐνέργειαν. οὐ μὴν ἄλλην γέ τινα πρόφασιν τῆς βλάβης εἰπεῖν ἔχει πλὴν τῆς παρὰ φύσιν θερμασίας. ἀλλʼ εἰ βλάπτει τὴν ἐνέργειαν ἡ παρὰ φύσιν θερμασία μὴ κατά τι συμβεβηκός, ἀλλὰ διὰ τὴν αὑτῆς οὐσίαν τε καὶ δύναμιν, ἐκ τῶν πρώτων ἂν εἴη νοσημάτων· καὶ μὴν οὐκ ἐνδέχεται τῶν πρώτων μὲν εἶναι νοσημάτων τὴν ἀμετρίαν τῆς θερμασίας, τὴν δʼ ἐνέργειαν ὑπὸ τῆς εὐκρασίας μὴ γίγνεσθαι. οὐδὲ γὰρ διʼ ἄλλο τι δυνατὸν γίγνεσθαι τὴν δυσκρασίαν αἰτίαν τῶν πρώτων νοσημάτων ἀλλʼ ἢ διὰ τὴν εὐκρασίαν διαφθειρομένην. τῷ γὰρ ὑπὸ ταύτης γίγνεσθαι τὰς ἐνεργείας ἀνάγκη καὶ τὰς πρώτας αὐτῶν βλάβας διαφθειρομένης γίγνεσθαι.

That is to say, it is because the [normal] activities arise from the eucrasia that the primary impairments of these activities necessarily arise the from derangement. I think, then, it has been proved to the satisfaction of those who are capable of seeing logical consequences, that, even according to Erasistratus' own argument, the cause of the normal functions is eucrasia of the Warm. Now, this being so, there is nothing further to prevent us from saying that, in the case of each function, eucrasia is followed by the more, and dyscrasia by the less favourable alternative. And, therefore, if this be the case, we must suppose blood to be the outcome of proportionate, and yellow bile of disproportionate heat. So we naturally find yellow bile appearing in greatest quantity in ourselves at the warm periods of life, in warm countries, at warm seasons of the year, and when we are in a warm condition;

ὅτι μὲν οὖν καὶ κατʼ αὐτὸν τὸν Ἐρασίστρατον ἡ εὐκρασία τοῦ θερμοῦ τῶν ἐνεργειῶν αἰτία, τοῖς θεωρεῖν τὸ ἀκόλουθον δυναμένοις ἱκανῶς ἀποδεδεῖχθαι νομίζω. τούτου δʼ ὑπάρχοντος ἡμῖν οὐδὲν ἔτι χαλεπὸν ἐφʼ ἑκάστης ἐνεργείας τῇ μὲν εὐκρασία τὸ βέλτιον ἕπεσθαι λέγειν, τῇ δὲ δυσκρασίᾳ τὰ χείρω. καὶ τοίνυν εἴπερ ταῦθʼ οὕτως ἔχει, τὸ μὲν αἷμα τῆς συμμέτρου θερμασίας, τὴν δὲ ξανθὴν χολὴν τῆς ἀμέτρου νομιστέον ὑπάρχειν ἔγγονον. οὕτω γὰρ καὶ ἡμῖν ἔν τε ταῖς θερμαῖς ἡλικίαις καὶ τοῖς θερμοῖς χωρίοις καὶ ταῖς ὥραις τοῦ ἔτους ταῖς θερμαῖς καὶ ταῖς θερμαῖς καταστάσεσιν, ὡσαύτως δὲ καὶ ταῖς θερμαῖς κράσεσι τῶν ἀνθρώπων καὶ τοῖς ἐπιτηδεύμασί τε καὶ τοῖς διαιτήμασι καὶ τοῖς νοσήμασι τοῖς θερμοῖς εὐλόγως ἡ ξανθὴ χολὴ πλείστη φαίνεται γιγνομένη.

similarly in people of warm temperaments, and in connection with warm occupations, modes of life, or diseases. And to be in doubt as to whether this humour has the genesis in the human body or is contained in the food is what you would expect from one who has — I will not say failed to see that, when those who are perfectly healthy have, under the compulsion of circumstances, to fast contrary to custom, their mouths become bitter and their urine bile-coloured, while they suffer from gnawing pains in the stomach — but has, as it were, just made a sudden entrance into the world, and is not yet familiar with the phenomena which occur there. Who, in fact, does not know that anything which is overcooked grows at first salt and afterwards bitter? And if you will boil honey itself, far the sweetest of all things, you can demonstrate that even this becomes quite bitter. For what may occur as a result of boiling in the case of other articles which are not warm by nature, exists naturally in honey; for this reason it does not become sweeter on being boiled, since exactly the same quantity of heat as is needed for the production of sweetness exists from beforehand in the honey. Therefore the external heat, which would be useful for insufficiently warm substances, becomes in the honey a source of damage, in fact an excess; and it is for this reason that honey, when boiled, can be demonstrated to become bitter sooner than the others. For the same reason it is easily transmuted into bile in those people who are naturally warm, or in their prime, since warm when associated with warm becomes readily changed into a disproportionate combination and turns into bile sooner than into blood. Thus we need a cold temperament and a cold period of life if we would have honey brought to the nature of blood. Therefore Hippocrates not improperly advised those who were naturally bilious not to take honey, since they were obviously of too warm a temperament. So also, not only Hippocrates, but all physicians say that honey is bad in bilious diseases but good in old age; some of them having discovered this through the indications afforded by its nature, and others simply through experiment, for the Empiricist physicians too have made precisely the same observation, namely, that honey is good for an old man and not for a young one, that it is harmful for those who are naturally bilious, and serviceable for those who are phlegmatic. In a word, in bodies which are warm either through nature, disease, time of life, season of the year, locality, or occupation, honey is productive of bile, whereas in opposite circumstances it produces blood.

But surely it is impossible that the same article of diet can produce in certain persons bile and in others blood, if it be not that the genesis of these humours is accomplished in the body. For if all articles of food contained bile from the beginning and of themselves, and did not produce it by undergoing change in the animal body, then they would produce it similarly in all bodies; the food which was bitter to the taste would, I take it, be productive of bile, while that which tasted good and sweet would not generate even the smallest quantity of bile. Moreover, not only honey but all other sweet substances are readily converted into bile in the aforesaid bodies which are warm for any of the reasons mentioned.

καὶ μὴν οὐκ ἐνδέχεται ταὐτὸν ἔδεσμα τοῖς μὲν χολὴν γεννᾶν, τοῖς δʼ αἷμα μὴ οὐκ ἐν τῷ σώματι τῆς γενέσεως αὐτῶν ἐπιτελουμένης. εἰ γὰρ δὴ οἴκοθέν γε καὶ παρʼ ἑαυτοῦ τῶν ἐδεσμάτων ἕκαστον ἔχον καὶ οὐκ ἐν τοῖς τῶν ζῴων σώμασι μεταβαλλόμενον ἐγέννα τὴν χολήν, ἐν ἅπασιν ἂν ὁμοίως αὐτὴν τοῖς σώμασιν ἐγέννα καὶ τὸ μὲν πικρὸν ἔξω γευομένοις ἦν ἂν οἶμαι χολῆς ποιητικόν, εἰ δέ τι γλυκὺ καὶ χρηστόν, οὐκ ἂν οὐδὲ τὸ βραχύτατον ἐξ αὐτοῦ χολῆς ἐγεννᾶτο. καὶ μὴν οὐ τὸ μέλι μόνον, ἀλλὰ καὶ τῶν ἄλλων ἕκαστον τῶν γλυκέων τοῖς προειρημένοις σώμασι τοῖς διʼ ὁτιοῦν τῶν εἰρημένων θερμοῖς οὖσιν εἰς χολὴν ἑτοίμως ἐξίσταται.

Well, I have somehow or other been led into this discussion, — not in accordance with my plan, but compelled by the course of the argument. This subject has been treated at great length by Aristotle and Praxagoras, who have correctly expounded the view of Hippocrates and Plato.

καίτοι ταῦτʼ οὐκ οἶδʼ ὅπως ἐξηνέχθην εἰπεῖν οὐ προελόμενος ἀλλʼ ὑπʼ αὐτῆς τοῦ λόγου τῆς ἀκολουθίας ἀναγκασθείς. εἴρηται δʼ ἐπὶ πλεῖστον ὑπὲρ αὐτῶν Ἀριστοτέλει τε καὶ Πραξαγόρᾳ τὴν Ἱπποκράτους καὶ Πλάτωνος γνώμην ὀρθῶς ἐξηγησαμένοις.

9. For this reason the things that we have said are not to be looked upon as proofs but rather as indications of the dullness of those who think differently, and who do not even recognise what is agreed on by everyone and is a matter of daily observation. As for the scientific proofs of all this, they are to be drawn from these principles of which I have already spoken — namely, that bodies act upon and are acted upon by each other in virtue of the Warm, Cold, Moist and Dry. And if one is speaking of any activity, whether it be exercised by vein, liver, arteries, heart, alimentary canal, or any part, one will be inevitably compelled to acknowledge that this activity depends upon the way in which the four qualities are blended. Thus I should like to ask the Erasistrateans why it is that the stomach contracts upon the food, and why the veins generate blood. There is no use in recognizing the mere fact of contraction, without also knowing the cause; if we know this, we shall also be able to rectify the failures of function. “This is no concern of ours,” they say; “we do not occupy ourselves with such causes as these; they are outside the sphere of the practitioner, and belong to that of the scientific investigator.” Are you, then, going to oppose those who maintain that the cause of the function of every organ is a natural eucrasia, that the dyscrasia is itself known as a disease, and that it is certainly by this that the activity becomes impaired? Or, on the other hand, will you be convinced by the proofs which the ancient writers furnished? Or will you take a midway course between these two, neither perforce accepting these arguments as true nor contradicting them as false, but suddenly becoming sceptics — Pyrrhonists, in fact? But if you do this you will have to shelter yourselves behind the Empiricist teaching. For how are you going to be successful in treatment, if you do not understand the real essence of each disease? Why, then, did you not call yourselves Empiricists from the beginning? Why do you confuse us by announcing that you are investigating natural activities with a view to treatment? If the stomach is, in a particular case, unable to exercise its peristaltic and grinding functions, how are we going to bring it back to the normal if we do not know the cause of its disability? What I say is that we must cool the over-heated stomach and warm the warm the chilled one; so also we must moisten the one which has become dried up, and conversely; so, too, in combinations of these conditions; if the stomach becomes at the same time warmer and drier than normally, the first principle of treatment is at once to chill and moisten it; and if it become colder and moister, it must be warmed and dried; so also in other cases. But how on earth are the followers of Erasistratus going to act, confessing as they do that they make no sort of investigation into the cause of disease? For the fruit of the enquiry into activities is that by knowing the causes of the dyscrasiae one may bring them back to the normal, since it is of no use for the purposes of treatment merely to know what the activity of each organ is.

9. μὴ τοίνυν ὡς ἀποδείξεις ὑφʼ ἡμῶν εἰρῆσθαι νομίζειν τὰ τοιαῦτα μᾶλλον ἢ περὶ τῆς τῶν ἄλλως γιγνωσκόντων ἀναισθησίας ἐνδείξεις, οἳ μηδὲ τὰ πρὸς ἁπάντων ὁμολογούμενα καὶ καθʼ ἑκάστην ἡμέραν φαινόμενα γιγνώσκουσιν· τὰς δʼ ἀποδείξεις αὐτῶν τὰς κατʼ ἐπιστήμην ἐξ ἐκείνων χρὴ λαμβάνειν τῶν ἀρχῶν, ὧν ἤδη καὶ πρόσθεν εἴπομεν, ὡς τὸ δρᾶν καὶ πάσχειν εἰς ἄλληλα τοῖς σώμασιν ὑπάρχει κατὰ τὸ θερμὸν καὶ ψυχρὸν καὶ ξηρὸν καὶ ὑγρόν. καὶ εἴτε φλέβας εἴθʼ ἧπαρ εἴτʼ ἀρτηρίας εἴτε καρδίαν εἴτε κοιλίαν εἴτʼ ἄλλο τι μόριον ἐνεργεῖν τις φήσειεν ἡντινοῦν ἐνέργειαν, ἀφύκτοις ἀνάγκαις ἀναγκασθήσεται διὰ τὴν ἐκ τῶν τεττάρων ποιὰν κρᾶσιν ὁμολογῆσαι τὴν ἐνέργειαν ὑπάρχειν αὐτῷ. διὰ τί γὰρ ἡ γαστὴρ περιστέλλεται τοῖς σιτίοις, διὰ τί δʼ αἱ φλέβες αἷμα γεννῶσι, παρὰ τῶν Ἐρασιστρατείων ἐδεόμην ἀκοῦσαι. τὸ γὰρ ὅτι περιστέλλεται μόνον αὐτὸ καθʼ ἑαυτὸ γιγνώσκειν οὐδέπω χρηστόν, εἰ μὴ καὶ τὴν αἰτίαν εἰδείημεν· οὕτω γὰρ ἂν οἶμαι καὶ τὰ σφάλματα θεραπεύσαιμεν. οὐ μέλει, φασίν, ἡμῖν οὐδὲ πολυπραγμονοῦμεν ἔτι τὰς τοιαύτας αἰτίας· ὑπὲρ ἰατρὸν γάρ εἰσι καὶ τῷ φυσικῷ προσήκουσι. πότερον οὖν οὐδʼ ἀντερεῖτε τῷ φάσκοντι τὴν μὲν εὐκρασίαν τὴν κατὰ φύσιν αἰτίαν εἶναι τῆς ἐνεργείας ἑκάστῳ τῶν ὀργάνων, τὴν δʼ αὖ δυσκρασίαν νόσον τʼ ἤδη καλεῖσθαι καὶ πάντως ὑπʼ αὐτῆς βλάπτεσθαι τὴν ἐνέργειαν; ἢ πεισθήσεσθε ταῖς τῶν παλαιῶν ἀποδείξεσιν; ἢ τρίτον τι καὶ μέσον ἑκατέρου τούτων πράξετε μήθʼ ὡς ἀληθέσι τοῖς λόγοις ἐξ ἀνάγκης πειθόμενοι μήτʼ ἀντιλέγοντες ὡς ψευδέσιν, ἀλλʼ ἀπορητικοί τινες ἐξαίφνης καὶ Πυρρώνειοι γενήσεσθε; καὶ μὴν εἰ τοῦτο δράσετε, τὴν ἐμπειρίαν ἀναγκαῖον ὑμῖν προστήσασθαι. τῷ γὰρ ἂν ἔτι τρόπῳ καὶ τῶν ἰαμάτων εὐποροίητε τὴν οὐσίαν ἑκάστου τῶν νοσημάτων ἀγνοοῦντες; τί οὖν οὐκ ἐξ ἀρχῆς ἐμπειρικοὺς ὑμᾶς αὐτοὺς ἐκαλέσατε; τί δὲ πράγμαθʼ ἡμῖν παρέχετε φυσικὰς ἐνεργείας ἐπαγγελλόμενοι ζητεῖν ἰάσεως ἕνεκεν; εἰ γὰρ ἀδύνατος ἡ γαστήρ ἐστί τινι περιστέλλεσθαι καὶ τρίβειν, πῶς αὐτὴν εἰς τὸ κατὰ φύσιν ἐπανάξομεν ἀγνοοῦντες τὴν αἰτίαν τῆς ἀδυναμίας; ἐγὼ μέν φημι τὴν μὲν ὑπερτεθερμασμένην ἐμψυκτέον ἡμῖν εἶναι, τὴν δʼ ἐψυγμένην θερμαντέον· οὕτω δὲ καὶ τὴν ἐξηρασμένην ὑγραντέον, τὴν δʼ ὑγρασμένην ξηραντέον. ἀλλὰ καὶ κατὰ συζυγίαν, εἰ θερμοτέρα τοῦ κατὰ φύσιν ἅμα καὶ ξηροτέρα τύχοι γεγενημένη, κεφάλαιον εἶναι τῆς ἰάσεως ἐμψύχειν θʼ ἅμα καὶ ὑγραίνειν· εἰ δʼ αὖ ψυχροτέρα τε καὶ ὑγροτέρα, θερμαίνειν τε καὶ ξηραίνειν κἀπὶ τῶν ἄλλων ὡσαύτως· οἱ δʼ ἀπʼ Ἐρασιστράτου τί ποτε καὶ πράξουσιν οὐδʼ ὅλως ζητεῖν τῶν ἐνεργειῶν τὰς αἰτίας ὁμολογοῦντες; ὁ γάρ τοι καρπὸς τῆς περὶ τῶν ἐνεργειῶν ζητήσεως οὗτός ἐστι, τὸ τὰς αἰτίας τῶν δυσκρασιῶν εἰδότα εἰς τὸ κατὰ φύσιν ἐπανάγειν αὐτάς, ὡς αὐτό γε μόνον τὸ γνῶναι τὴν ἑκάστου τῶν ὀργάνων ἐνέργειαν ἥτις ἐστὶν οὔπω χρηστὸν εἰς τὰς ἰάσεις.

Now, it seems to me that Erasistratus is unaware of this fact also, that the actual disease is that condition of the body which, not accidentally, but primarily and of itself, impairs the normal function. How, then, is he going to diagnose or cure diseases if he is entirely ignorant of what they are, and of what kind and number? As regards the stomach, certainly, Erasistratus held that one should at least investigate how it digests the food. But why was not investigation also made as to the primary originative cause of this? And, as regards the veins and the blood, he omitted even to ask the question “how?”

Ἐρασίστρατος δέ μοι δοκεῖ καὶ αὐτὸ τοῦτʼ ἀγνοεῖν, ὡς, ἥτις ἂν ἐν τῷ σώματι διάθεσις βλάπτῃ τὴν ἐνέργειαν μὴ κατά τι συμβεβηκὸς ἀλλὰ πρώτως τε καὶ καθʼ ἑαυτήν, αὕτη τὸ νόσημά ἐστιν αὐτό. πῶς οὖν ἔτι διαγνωστικός τε καὶ ἰατικὸς ἔσται τῶν νοσημάτων ἀγνοῶν ὅλως αὐτὰ τίνα τʼ ἐστὶ καὶ πόσα καὶ ποῖα; κατὰ μὲν δὴ τὴν γαστέρα τό γε τοσοῦτον Ἐρασίστρατος ἠξίωσε ζητεῖσθαι τὸ πῶς πέττεται τὰ σιτία·

Yet neither Hippocrates nor any of the other physicians or philosophers whom I mentioned a short while ago thought it right to omit this; they say that when the heat which exists naturally in every animal is well blended and moderately moist it generates blood; for this reason they also say that the blood is a virtually warm and moist humour, and similarly also that yellow bile is warm and dry, even though for the most part it appears moist. (For in them the apparently dry would seem to differ from the virtually dry.) Who does not know that brine and sea-water preserve meat and keep it uncorrupted, whilst all other water — the drinkable kind — readily spoils and rots it? And who does not know that when yellow bile is contained in large quantity in the stomach, we are troubled with an unquenchable thirst, and that when we vomit this up, we at once become much freer from thirst than if we had drunk very large quantities of fluid? Therefore this humour has been very properly termed warm, and also virtually dry. And, similarly, phlegm has been called cold and moist; for about this also clear proofs have been given by Hippocrates and the other Ancients.

τὸ δʼ ἥτις πρώτη τε καὶ ἀρχηγὸς αἰτία τούτου, πῶς οὐκ ἐπεσκέψατο; κατὰ δὲ τὰς φλέβας καὶ τὸ αἷμα καὶ αὐτὸ τὸ πῶς παρέλιπεν. ἀλλʼ οὔθʼ Ἱπποκράτης οὔτʼ ἄλλος τις ὧν ὀλίγῳ πρόσθεν ἐμνημόνευσα φιλοσόφων ἢ ἰατρῶν ἄξιον ᾤετʼ εἶναι παραλιπεῖν· ἀλλὰ τὴν κατὰ φύσιν ἐν ἑκάστῳ ζῴῳ θερμασίαν εὔκρατόν τε καὶ μετρίως ὑγρὰν οὖσαν αἵματος εἶναί φασι γεννητικὴν καὶ διʼ αὐτό γε τοῦτο καὶ τὸ αἷμα θερμὸν καὶ ὑγρὸν εἶναί φασι τῇ δυνάμει χυμόν, ὥσπερ τὴν ξανθὴν χολὴν θερμὴν καὶ ξηρὰν εἶναι, εἰ καὶ ὅτι μάλισθʼ ὑγρὰ φαίνεται. διαφέρειν γὰρ αὐτοῖς δοκεῖ τὸ κατ φαντασίαν ὑγρὸν τοῦ κατὰ δύναμιν. ἢ τίς οὐκ οἶδεν, ὡς ἅλμη μὲν καὶ θάλαττα ταριχεύει τὰ κρέα καὶ ἄσηπτα διαφυλάττει, τὸ δʼ ἄλλο πᾶν ὕδωρ τὸ πότιμον ἑτοίμως διαφθείρει τε καὶ σήπει; τίς δʼ οὐκ οἶδεν, ὡς ξανθῆς χολῆς ἐν τῇ γαστρὶ περιεχομένης πολλῆς ἀπαύστῳ δίψει συνεχόμεθα καὶ ὡς ἐμέσαντες αὐτὴν εὐθὺς ἄδιψοι γιγνόμεθα μᾶλλον ἢ εἰ πάμπολυ ποτὸν προσηράμεθα; θερμὸς οὖν εὐλόγως ὁ χυμὸς οὗτος εἴρηται καὶ ξηρὸς κατὰ δύναμιν, ὥσπερ γε καὶ τὸ φλέγμα ψυχρὸν καὶ ὑγρόν.

Prodicus also, when in his book “On the Nature of Man” he gives the name “phlegm” to that element in the humours which has been burned or, as it were, over-roasted, while using a different terminology, still keeps to the fact just as the others do; this man's innovations in nomenclature have also been amply done justice to by Plato. Thus, the white-coloured substance which everyone else calls phlegm, and which Prodicus calls blenna [mucus], is the well-known cold, moist humour which collects mostly in old people and in those who have been chilled in some way, and not even a lunatic could say that this was anything else than cold and moist.

ἐναργεῖς γὰρ καὶ περὶ τούτου πίστεις Ἱπποκράτει τε καὶ τοῖς ἄλλοις εἴρηνται παλαιοῖς. Πρόδικος δʼ ἐν τῷ περὶ φύσεως ἀνθρώπου γράμματι τὸ συγκεκαυμένον καὶ οἷον ὑπερωπτημένον ἐν τοῖς χυμοῖς ὀνομάζων φλέγμα παρὰ τὸ πεφλέχθαι τῇ λέξει μὲν ἑτέρως χρῆται, φυλάττει μέντοι τὸ πρᾶγμα κατὰ ταὐτὸ τοῖς ἄλλοις. τὴν δʼ ἐν τοῖς ὀνόμασι τἀνδρὸς τούτου καινοτομίαν ἱκανῶς ἐνδείκνυται καὶ Πλάτων.

If, then, there is a warm and moist humour, and another which is warm and dry, and yet another which is moist and cold, is there none which is virtually cold and dry? Is the fourth combination of temperaments, which exists in all other things, non-existent in the humours alone? No; the black bile is such a humour. This, according to intelligent physicians and philosophers, tends to be in excess, as regards seasons, mainly in the fall of the year, and, as regards ages, mainly after the prime of life. And, similarly, also they say that there are cold and dry modes of life, regions, constitutions, and diseases. Nature, they suppose, is not defective in this single combination; like the three other combinations, it extends everywhere.

ἀλλὰ τοῦτό γε τὸ πρὸς ἁπάντων ἀνθρώπων ὀνομαζόμενον φλέγμα τὸ λευκὸν τὴν χρόαν, ὃ βλένναν ὀνομάζει Πρόδικος, ὁ ψυχρὸς καὶ ὑγρὸς χυμός ἐστιν οὗτος καὶ πλεῖστος τοῖς τε γέρουσι καὶ τοῖς ὁπωσδήποτε ψυγεῖσιν ἀθροίζεται καὶ οὐδεὶς οὐδὲ μαινόμενος ἂν ἄλλο τι ἢ ψυχρὸν καὶ ὑγρὸν εἴποι ἂν αὐτόν. ἆρʼ οὖν θερμὸς μέν τίς ἐστι καὶ ὑγρὸς χυμὸς καὶ θερμὸς καὶ ξηρὸς ἕτερος καὶ ὑγρὸς καὶ ψυχρὸς ἄλλος, οὐδεὶς δʼ ἐστὶ ψυχρὸς καὶ ξηρὸς τὴν δύναμιν, ἀλλʼ ἡ τετάρτη συζυγία τῶν κράσεων ἐν ἅπασι τοῖς ἄλλοις ὑπάρχουσα μόνοις τοῖς χυμοῖς οὐχ ὑπάρχει; καὶ μὴν ἥ γε μέλαινα χολὴ τοιοῦτός ἐστι χυμός, ὃν οἱ σωφρονοῦντες ἰατροὶ καὶ φιλόσοφοι πλεονεκτεῖν ἔφασαν τῶν μὲν ὡρῶν τοῦ ἔτους ἐν φθινοπώρῳ μάλιστα, τῶν δʼ ἡλικιῶν ἐν ταῖς μετὰ τὴν ἀκμήν.

At this point, also, I would gladly have been able to ask Erasistratus whether his “artistic” Nature has not constructed any organ for clearing away a humour such as this. For whilst there are two organs for the excretion of urine, and another of considerable size for that of yellow bile, does the humour which is more pernicious than these wander about persistently in the veins mingled with the blood? Yet Hippocrates says, “Dysentery is a fatal condition if it proceeds from black bile”; while that proceeding from yellow bile is by no means deadly, and most people recover from it; this proves how much more pernicious and acrid in its potentialities is black than yellow bile. Has Erasistratus, then, not read the book, “On the Nature of Man,” any more than any of the rest of Hippocrates' writings, that he so carelessly passes over the consideration of the humours? Or, does the know it, and yet voluntarily neglect one of the finest studies in medicine? Thus he ought not to have said anything about the spleen, nor have stultified himself by holding that an artistic Nature would have prepared so large an organ for no purpose. As a matter of fact, not a matter of fact, not only Hippocrates and Plato — who are no less authorities on Nature than is Erasistratus — say that this viscus also is one of those which cleanse the blood, but there are thousands of the ancient physicians and philosophers as well who are in agreement with them. Now, all of these the high and mighty Erasistratus affected to despise, and he neither contradicted them nor even so much as mentioned their opinion. Hippocrates, indeed, says that the spleen wastes in those people in whom the body is in good condition, and all those physicians also who base themselves on experience agree with this. Again, in those cases in which the spleen is large and is increasing from internal suppuration, it destroys the body and fills it with evil humours; this again is agreed on, not only by Hippocrates, but also by Plato and many others, including the Empiric physicians. And the jaundice which occurs when the spleen is out of order is darker in colour, and the cicatrices of ulcers are dark. For, generally speaking, when the spleen is drawing the atrabiliary humour into itself to a less degree than is proper, the blood is unpurified, and the whole body takes on a bad colour. And when does it draw this in to a less degree than proper? Obviously, when it [the spleen] is in a bad condition. Thus, just as the kidneys, whose function it is to attract the urine, do this badly when they are out or order, so also the spleen, which has in itself a native power of attracting an atrabiliary quality, if it ever happens to be weak, must necessarily exercise this attraction badly, with the result that the blood becomes thicker and darker.

οὕτω δὲ καὶ διαιτήματα καὶ χωρία καὶ καταστάσεις καὶ νόσους τινὰς ψυχρὰς καὶ ξηρὰς εἶναί φασιν· οὐ γὰρ δὴ χωλὴν ἐν ταύτῃ μόνῃ τῇ συζυγίᾳ τὴν φύσιν εἶναι νομίζουσιν ἀλλʼ ὥσπερ τὰς ἄλλας τρεῖς οὕτω καὶ τήνδε διὰ πάντων ἐκτετάσθαι. ηὐξάμην οὖν κἀνταῦθʼ ἐρωτῆσαι δύνασθαι τὸν Ἐρασίστρατον, εἰ μηδὲν ὄργανον ἡ τεχνικὴ φύσις ἐδημιούργησε καθαρτικὸν τοῦ τοιούτου χυμοῦ, ἀλλὰ τῶν μὲν οὔρων ἄρα τῆς διακρίσεώς ἐστιν ὄργανα δύο καὶ τῆς ξανθῆς χολῆς ἕτερον οὐ σμικρόν, ὁ δὲ τούτων κακοηθέστερος χυμὸς ἀλᾶται διὰ παντὸς ἐν ταῖς φλεψὶν ἀναμεμιγμένος τῷ αἵματι. καίτοι "Δυσεντερίη," φησί που Ἱπποκράτης, "ἢν ἀπὸ χολῆς μελαίνης ἄρξηται, θανάσιμον," οὐ μὴν ἥ γʼ ἀπὸ τῆς ξανθῆς χολῆς ἀρχομένη πάντως ὀλέθριος, ἀλλʼ οἱ πλείους ἐξ αὐτῆς διασῴζονται. τοσούτῳ κακοηθεστέρα τε καὶ δριμυτέρα τὴν δύναμιν ἡ μέλαινα χολὴ τῆς ξανθῆς ἐστιν. ἆρʼ οὖν οὔτε τῶν ἄλλων ἀνέγνω τι τῶν τοῦ Ἱπποκράτους γραμμάτων ὁ Ἐρασίστρατος οὐδὲν οὔτε τὸ περὶ φύσεως ἀνθρώπου βιβλίον, ἵνʼ οὕτως ἀργῶς παρέλθοι τὴν περὶ τῶν χυμῶν ἐπίσκεψιν, ἢ γιγνώσκει μέν, ἑκὼν δὲ παραλείπει καλλίστην τῆς τέχνης θεωρίαν; ἐχρῆν οὖν αὐτὸν μηδὲ περὶ τοῦ σπληνὸς εἰρηκέναι τι μηδʼ ἀσχημονεῖν ὑπὸ τῆς τεχνικῆς φύσεως ὄργανον τηλικοῦτον μάτην ἡγούμενον κατεσκευάσθαι. καὶ μὴν οὐχ Ἱπποκράτης μόνον ἢ Πλάτων, οὐδέν τι χείρους Ἐρασιστράτου περὶ φύσιν ἄνδρες, ἕν τι τῶν καθαιρόντων τὸ αἷμα καὶ τοῦτʼ εἶναί φασι τὸ σπλάγχνον, ἀλλὰ καὶ μυρίοι σὺν αὐτοῖς ἄλλοι τῶν παλαιῶν ἰατρῶν τε καὶ φιλοσόφων, ὧν ἁπάντων προσποιησάμενος ὑπερφρονεῖν ὁ γενναῖος Ἐρασίστρατος οὔτʼ ἀντεῖπεν οὔθʼ ὅλως τῆς δόξης αὐτῶν ἐμνημόνευσε. καὶ μὴν ὅσοις γε τὸ σῶμα θάλλει, τούτοις ὁ σπλὴν φθίνει, φησὶν Ἱπποκράτης, καὶ οἱ ἀπὸ τῆς ἐμπειρίας ὁρμώμενοι πάντες ὁμολογοῦσιν ἰατροί. καὶ ὅσοις γʼ αὖ μέγας καὶ ὕπουλος αὐξάνεται, τούτοις καταφθείρει τε καὶ κακόχυμα τὰ σώματα τίθησιν, ὡς καὶ τοῦτο πάλιν οὐχ Ἱπποκράτης μόνον ἀλλὰ καὶ Πλάτων ἄλλοι τε πολλοὶ καὶ οἱ ἀπὸ τῆς ἐμπειρίας ὁμολογοῦσιν ἰατροί. καὶ οἱ ἀπὸ σπληνὸς δὲ κακοπραγοῦντος ἴκτεροι μελάντεροι καὶ τῶν ἑλκῶν αἱ οὐλαὶ μέλαιναι. καθόλου γάρ, ὅταν ἐνδεέστερον ἢ προσῆκεν εἰς ἑαυτὸν ἕλκῃ τὸν μελαγχολικὸν χυμόν, ἀκάθαρτον μὲν τὸ αἷμα, κακόχρουν δὲ τὸ πᾶν γίγνεται σῶμα. πότε δʼ ἐνδεέστερον ἕλκει; ἢ δῆλον ὅτι κακῶς διακείμενος;

Now all these points, affording as they do the greatest help in the diagnosis and in the cure of disease were entirely passed over by Erasistratus, and he pretended to despise these great men — he who does not despise ordinary people, but always jealously attacks the most absurd doctrines. Hence, it was clearly because he had nothing to say against the statements made by the Ancients regarding the function and utility of the spleen, and also because he could discover nothing new himself, that he ended by saying nothing at all. I, however, for my part, have demonstrated, firstly from the causes by which everything throughout nature is governed (by the causes I mean the Warm, Cold, Dry and Moist) and secondly, from obvious bodily phenomena, that there must needs be a cold and dry humour. And having in the next place drawn attention to the fact that this humour is black bile [atrabiliary] and that the viscus which clears it away is the spleen — having pointed this out by help of as few as possible of the proofs given by ancient writers, I shall now proceed to what remains of the subject in hand.

ὥσπερ οὖν τοῖς νεφροῖς ἐνεργείας οὔσης ἕλκειν τὰ οὖρα κακῶς ἕλκειν ὑπάρχει κακοπραγοῦσιν, οὕτω καὶ τῷ σπληνὶ ποιότητος μελαγχολικῆς ἑλκτικὴν ἐν ἑαυτῷ δύναμιν ἔχοντι σύμφυτον ἀρρωστήσαντί ποτε ταύτην ἀναγκαῖον ἕλκειν κακῶς κἀν τῷδε παχύτερον ἤδη καὶ μελάντερον γίγνεσθαι τὸ αἷμα. ταῦτʼ οὖν ἅπαντα πρός τε τὰς διαγνώσεις τῶν νοσημάτων καὶ τὰς ἰάσεις μεγίστην παρεχόμενα χρείαν ὑπερεπήδησε τελέως ὁ Ἐρασίστρατος καὶ καταφρονεῖν προσεποιήσατο τηλικούτων ἀνδρῶν ὁ μηδὲ τῶν τυχόντων καταφρονῶν ἀλλʼ ἀεὶ φιλοτίμως ἀντιλέγων ταῖς ἤλιθιωτάταις δόξαις. ᾧ καὶ δῆλον, ὡς οὐδὲν ἔχων οὔτʼ ἀντειπεῖν τοῖς πρεσβυτέροις ὑπὲρ ὧν ἀπεφήναντο περὶ σπληνὸς ἐνεργείας τε καὶ χρείας οὔτʼ αὐτὸς ἐξευρίσκων τι καινὸν εἰς τὸ μηδὲν ὅλως εἰπεῖν ἀφίκετο. ἀλλʼ ἡμεῖς γε πρῶτον μὲν ἐκ τῶν αἰτίων, οἷς ἅπαντα διοικεῖται τὰ κατὰ τὰς φυσεις, τοῦ θερμοῦ λέγω καὶ ψυχροῦ καὶ ξηροῦ καὶ ὑγροῦ, δεύτερον δʼ ἐξ αὐτῶν τῶν ἐναργῶς φαινομένων κατὰ τὸ σῶμα ψυχρὸν καὶ ξηρὸν εἶναί τινα χρῆναι χυμὸν ἀπεδείξαμεν.

What else, then, remains but to explain clearly what it is that happens in the generation of the humours, according to the belief and demonstration of the Ancients? This will be more clearly understood from a comparison. Imagine, then, some new wine which has been not long ago pressed from the grape, and which is fermenting and undergoing alteration through the agency of its contained heat. Imagine next two residual substances produced during this process of alteration, the one tending to be light and air-like and the other to be heavy and more of the nature of earth; of these the one, as I understand, they call the flower and the other the lees. Now you may correctly compare yellow bile to the first of these, and black bile to the latter, although these humours have not the same appearance when the animal is in normal health as that which they often show when it is not so; for then the yellow bile becomes vitelline, being so termed because it becomes like the yolk of an egg, both in colour and density; and again, even the black bile itself becomes much more malignant than when in its normal condition, but no particular name has been given to [such a condition of] the humour, except that some people have called it corrosive or acetose, because it also becomes sharp like vinegar and corrodes the animal's body — as also the earth, if it be poured out upon it — and it produces a kind of fermentation and seething, accompanied by bubbles — an abnormal putrefaction having become added to the natural condition of the black humour. It seems to me also that most of the ancient physicians give the name black humour and not black bile to the normal portion of this humour, which is discharged from the bowel and which also frequently rises to the top [of the stomach-contents]; and they call black bile that part which, through a kind of combustion and putrefaction, has had its quality changed to acid. There is no need, however, to dispute about names, but we must realise the facts, which are as follow:-

ἑξῆς δʼ, ὅτι καὶ μελαγχολικὸς οὗτος ὑπάρχει καὶ τὸ καθαῖρον αὐτὸν σπλάγχνον ὁ σπλήν ἐστιν, διὰ βραχέων ὡς ἔνι μάλιστα τῶν τοῖς παλαιοῖς ἀποδεδειγμένων ἀναμνήσαντες ἐπὶ τὸ λεῖπον ἔτι τοῖς παροῦσι λόγοις ἀφιξόμεθα. τί δʼ ἂν εἴη λεῖπον ἄλλο γʼ ἢ ἐξηγήσασθαι σαφῶς, οἷόν τι βούλονταί τε καὶ ἀποδεικνύουσι περὶ τὴν τῶν χυμῶν γένεσιν οἱ παλαιοὶ συμβαίνειν. ἐναργέστερον δʼ ἂν γνωσθείη διὰ παραδείγματος. οἶνον δή μοι νόει γλεύκινον οὐ πρὸ πολλοῦ τῶν σταφυλῶν ἐκτεθλιμμένον ζέοντά τε καὶ ἀλλοιούμενον ὑπὸ τῆς ἐν αὐτῷ θερμασίας· ἔπειτα κατὰ τὴν αὐτοῦ μεταβολὴν δύο γεννώμενα περιττώματα τὸ μὲν κουφότερόν τε καὶ ἀερωδέστερον, τὸ δὲ βαρύτερόν τε καὶ γεωδέστερον, ὧν τὸ μὲν ἄνθος, οἶμαι, τὸ δὲ τρύγα καλοῦσι. τούτων τῷ μὲν ἑτέρῳ τὴν ξανθὴν χολήν, τῷ δʼ ἑτέρῳ τὴν μέλαιναν εἰκάζων οὐκ ἂν ἁμάρτοις, οὐ τὴν αὐτὴν ἐχόντων ἰδέαν τῶν χυμῶν τούτων ἐν τῷ κατὰ φύσιν διοικεῖσθαι τὸ ζῷον, οἵαν καὶ παρὰ φύσιν ἔχοντος ἐπιφαίνονται πολλάκις. ἡ μὲν γὰρ ξανθὴ λεκιθώδης γίγνεται· καὶ γὰρ ὀνομάζουσιν οὕτως αὐτήν, ὅτι ταῖς τῶν ὠῶν λεκίθοις ὁμοιοῦται κατά τε χρόαν καὶ πάχος. ἡ δʼ αὖ μέλαινα κακοηθέστερα μὲν πολὺ καὶ αὕτη τῆς κατὰ φύσιν· ὄνομα δʼ οὐδὲν ἴδιον κεῖται τῷ τοιούτῳ χυμῷ, πλὴν εἴ πού τινες ἢ ξυστικὸν ἢ ὀξώδη κεκλήκασιν αὐτόν, ὅτι καὶ δριμὺς ὁμοίως ὄξει γίγνεται καὶ ξύει γε τὸ σῶμα τοῦ ζῴου καὶ τὴν γῆν, εἰ κατʼ αὐτῆς ἐκχυθείη, καί τινα μετὰ πομφολύγων οἷον ζύμωσίν τε καὶ ζέσιν ἐργάζεται, σηπεδόνος ἐπικτήτου προσελθούσης ἐκείνῳ τῷ κατὰ φύσιν ἔχοντι χυμῷ τῷ μέλανι. καί μοι δοκοῦσιν οἱ πλεῖστοι τῶν παλαιῶν ἰατρῶν αὐτὸ μὲν τὸ κατὰ φύσιν ἔχον τοῦ τοιούτου χυμοῦ καὶ διαχωροῦν κάτω καὶ πολλάκις ἐπιπολάζον ἄνω μέλανα καλεῖν χυμόν, οὐ μέλαιναν χολήν, τὸ δʼ ἐκ συγκαύσεώς τινος καὶ σηπεδόνος εἰς τὴν ὀξεῖαν μεθιστάμενον ποιότητα μέλαιναν ὀνομάζειν χολήν.

In the genesis of blood, everything in the nutriment which belongs naturally to the thick and earth-like part of the food, and which does not take on well the alteration produced by the innate heat — all this the spleen draws into itself. On the other hand, that part of the nutriment which is roasted, so to speak, or burnt (this will be the warmest and sweetest part of it, like honey and fat), becomes yellow bile, and is cleared away through the so-called biliary vessels; now, this is thin, moist, and fluid, not like what it is when, having been roasted to an excessive degree, it becomes yellow, fiery, and thick, like the yolk of eggs; for this latter is already abnormal, while the previously mentioned state is natural. Similarly with the black humour: that which does not yet produce, as I say, this seething and fermentation on the ground, is natural, while that which has taken over this character and faculty is unnatural; it has assumed an acridity owing to the combustion caused by abnormal heat, and has practically become transformed into ashes. In somewhat the same way burned lees differ from unburned. The former is a warm substance, able to burn, dissolve, and destroy the flesh. The other kind, which has not yet undergone combustion, one may find the physicians employing for the same purposes that one uses the so-called potter's earth and other substances which have naturally a combined drying and chilling action.

ἀλλὰ περὶ μὲν τῶν ὀνομάτων οὐ χρὴ διαφέρεσθαι, τὸ δʼ ἀληθὲς ὧδʼ ἔχον εἰδέναι. κατὰ τὴν τοῦ αἵματος γένεσιν ὅσον ἂν ἱκανῶς παχὺ καὶ γεῶδες ἐκ τῆς τῶν σιτίων φύσεως ἐμφερόμενον τῇ τροφῇ μὴ δέξηται καλῶς τὴν ἐκ τῆς ἐμφύτου θερμασίας ἀλλοίωσιν, ὁ σπλὴν εἰς ἑαυτὸν ἕλκει τοῦτο. τὸ δʼ ὀπτηθέν, ὡς ἄν τις εἴποι, καὶ συγκαυθὲν τῆς τροφῆς, εἴη δʼ ἂν τοῦτο τὸ θερμότατον ἐν αὐτῇ καὶ γλυκύτατον, οἷον τό τε μέλι καὶ ἡ πιμελή, ξανθὴ γενόμενον χολὴ διὰ τῶν χοληδόχων ὀνομαζομένων ἀγγείων ἐκκαθαίρεται. λεπτὸν δʼ ἐστὶ τοῦτο καὶ ὑγρὸν καὶ Ῥυτὸν οὐχ ὥσπερ ὅταν ὀπτηθὲν ἐσχάτως ξανθὸν καὶ πυρῶδες καὶ παχὺ γένηται ταῖς τῶν ὠῶν ὅμοιον λεκίθοις. τοῦτο μὲν γὰρ ἤδη παρὰ φύσιν· θάτερον δὲ τὸ πρότερον εἰρημένον κατὰ φύσιν ἐστίν· ὥσπερ γε καὶ τοῦ μέλανος χυμοῦ τὸ μὲν μήπω τὴν οἷον ζέσιν τε καὶ ζύμωσιν τῆς γῆς ἐργαζόμενον κατὰ φύσιν ἐστί, τὸ δʼ εἰς τοιαύτην μεθιστάμενον ἰδέαν τε καὶ δύναμιν ἤδη παρὰ φύσιν, ὡς ἂν τὴν ἐκ τῆς συγκαύσεως τοῦ παρὰ φύσιν θερμοῦ προσειληφὸς δριμύτητα καὶ οἷον τέφρα τις ἤδη γεγονός. ὧδέ πως καὶ ἡ κεκαυμένη τρὺξ τῆς ἀκαύστου διήνεγκε. θερμὸν γάρ τι χρῆμα αὕτη γʼ ἱκανῶς ἐστιν, ὥστε καίειν τε καὶ τήκειν καὶ διαφθείρειν τὴν σάρκα.

Now the vitelline bile also may take on the appearance of this combusted black bile, if ever it chance to be roasted, so to say, by fiery heat. And all the other forms of bile are produced, some the from blending of those mentioned, others being, as it were, transition-stages in the genesis of these or in their conversion into one another. And they differ in that those first mentioned are unmixed and unique, while the latter forms are diluted with various kinds of serum. And all the serums in the humours are waste substances, and the animal body needs to be purified from them. There is, however, a natural use for the humours first mentioned, both thick and thin; the blood is purified both by the spleen and by the bladder beside the liver, and a part of each of the two humours is put away, of such quantity and quality that, if it were carried all over the body, it would do a certain amount of harm. For that which is decidedly thick and earthy in nature, and has entirely escaped alteration in the liver, is drawn by the spleen into itself; the other part which is only moderately thick, after being elaborated [in the liver], is carried all over the body. For the blood in many parts of the body has need of a certain amount of thickening, as also, I take it, of the fibres which it contains. And the use of these has been discussed by Plato, and it will also be discussed by me in such of my treatises as may deal with the use of parts. And the blood also needs, not least, the yellow humour, which has as yet not reached the extreme stage of combustion; in the treatises mentioned it will be pointed out what purpose is subserved by this.

τῇ δʼ ἑτέρᾳ τῇ μήπω κεκαυμένῃ τοὺς ἰατροὺς ἔστιν εὑρεῖν χρωμένους εἰς ὅσαπερ καὶ τῇ γῇ τῇ καλουμένῃ κεραμίτιδι καὶ τοῖς ἄλλοις, ὅσα ξηραίνειν θʼ ἅμα καὶ ψύχειν πέφυκεν. εἰς τὴν τῆς οὕτω συγκαυθείσης μελαίνης χολῆς ἰδέαν καὶ ἡ λεκιθώδης ἐκείνη μεθίσταται πολλάκις, ὅταν καὶ αὐτή ποθʼ οἷον ὀπτηθεῖσα τύχῃ πυρώδει θερμασίᾳ. τὰ δʼ ἄλλα τῶν χολῶν εἴδη σύμπαντα τὰ μὲν ἐκ τῆς τῶν εἰρημένων κράσεως γίγνεται, τὰ δʼ οἷον ὁδοί τινές εἰσι τῆς τούτων γενέσεώς τε καὶ εἰς ἄλληλα μεταβολῆς. διαφέρουσι δὲ τῷ τὰς μὲν ἀκράτους εἶναι καὶ μόνας, τὰ δʼ οἷον ὀρροῖς τισιν ἐξυγρασμένας. ἀλλʼ οἱ μὲν ὀρροὶ τῶν χυμῶν ἅπαντες περιττώματα καὶ καθαρὸν αὐτῶν εἶναι δεῖται τοῦ ζῴου τὸ σῶμα. τῶν δʼ εἰρημένων χυμῶν ἐστί τις χρεία τῇ φύσει καὶ τοῦ παχέος καὶ τοῦ λεπτοῦ καὶ καθαίρεται πρός τε τοῦ σπληνὸς καὶ τῆς ἐπὶ τῷ ἥπατι κύστεως τὸ αἷμα καὶ ἀποτίθεται τοσοῦτόν τε καὶ τοιοῦτον ἑκατέρου μέρος, ὅσον καὶ οἷον, εἴπεο εἰς ὅλον ἠνέχθη τοῦ ζῴου τὸ σῶμα, βλάβην ἄν τινʼ εἰργάσατο. τὸ γὰρ ἱκανῶς παχὺ καὶ γεῶδες καὶ τελέως διαπεφευγὸς τὴν ἐν τῷ ἥπατι μεταβολὴν ὁ σπλὴν εἰς ἑαυτὸν ἕλκει· τὸ δʼ ἄλλο τὸ μετρίως παχὺ σὺν τῷ κατειργάσθαι πάντη φέρεται. δεῖται γὰρ ἐν πολλοῖς τοῦ ζῴου μορίοις παχύτητός τινος τὸ αἷμα καθάπερ οἶμαι καὶ τῶν ἐμφερομένων ἰνῶν. καὶ εἴρηται μὲν καὶ Πλάτωνι περὶ τῆς χρείας αὐτῶν, εἰρήσεται δὲ καὶ ἡμῖν ἐν ἐκείνοις τοῖς γράμμασιν, ἐν οἷς ἂν τὰς χρείας τῶν μορίων διερχώμεθα·

Now Nature has made no organ for clearing away phlegm, this being cold and moist, and, as it were, half-digested nutriment; such a substance, therefore, does not need to be evacuated, but remains in the body and undergoes alteration there. And perhaps one cannot properly give the name of phlegm to the surplus-substance which runs down from the brain, but one should call it mucus [blenna] or coryza — as, in fact, it is actually termed; in any case it will be pointed out, in the treatise “On the Use of Parts,” how Nature has provided for the evacuation of this substance. Further, the device provided by Nature which ensures that the phlegm which forms in the stomach and intestines may be evacuated in the most rapid and effective way possible — this also will be described in that commentary. As to that portion of the phlegm which is carried in the veins, seeing that this is of service to the animal, it requires no evacuation. Here too, then, we must pay attention and recognise that, just as in the case of each of the two kinds of bile, there is one part which is useful to the animal and in accordance with its nature, while the other part is useless and contrary to nature, so also is it with the phlegm; such of it as is sweet is useful to the animal and according to nature, while, as to such of it as has become bitter or salt, that part which is bitter is completely undigested, while that part which is salt has undergone putrefaction. And the term “complete indigestion ” refers of course to the second digestion — that which takes place in the veins; it is not a failure of the first digestion — that in the alimentary canal — for it would not have become a humour at the outset if it had escaped this digestion also.

δεῖται δʼ οὐχ ἥκιστα καὶ τοῦ ξανθοῦ χυμοῦ τοῦ μήπω πυρώδους ἐσχάτως γεγενημένου τὸ αἷμα καὶ τίς αὐτῷ καὶ ἡ παρὰ τοῦδε χρεία, διʼ ἐκείνων εἰρήσεται. φλέγματος δʼ οὐδὲν ἐποίησεν ἡ φύσις ὄργανον καθαρτικόν, ὅτι ψυχρὸν καὶ ὑγρόν ἐστι καὶ οἷον ἡμίπεπτός τις τροφή. δεῖται τοίνυν οὐ κενοῦσθαι τὸ τοιοῦτον ἀλλʼ ἐν τῷ σώματι μένον ἀλλοιοῦσθαι. τὸ δʼ ἐξ ἐγκεφάλου καταρρέον περίττωμα τάχα μὲν ἂν οὐδὲ φλέγμα τις ὀρθῶς ἀλλὰ βλένναν τε καὶ κόρυζαν, ὥσπερ οὖν καὶ ὀνομάζεται, καλοίη. εἰ δὲ μή, ἀλλʼ ὅτι γε τῆς τούτου κενώσεως ὀρθῶς ἡ φύσις προὐνοήσατο, καὶ τοῦτʼ ἐν τοῖς περὶ χρείας μορίων εἰρήσεται. καὶ γὰρ οὖν καὶ τὸ κατά τε τὴν γαστέρα καὶ τὰ ἔντερα συνιστάμενον φλέγμα ὅπως ἂν ἐκκενωθῇ καὶ αὐτὸ τάχιστά τε καὶ κάλλιστα, τὸ παρεσκευασμένον τῇ φύσει μηχάνημα διʼ ἐκείνων εἰρήσεται καὶ αὐτὸ τῶν ὑπομνημάτων. ὅσον οὖν ἐμφέρεται ταῖς φλεψὶ φλέγμα χρήσιμον ὑπάρχον τοῖς ζῴοις, οὐδεμιᾶς δεῖται κενώσεως. προσέχειν δὲ χρὴ κἀνταῦθα τὸν νοῦν καὶ γιγνώσκειν, ὥσπερ τῶν χολῶν ἑκατέρας τὸ μέν τι χρήσιμόν ἐστι καὶ κατὰ φύσιν τοῖς ζῴοις, τὸ δʼ ἄχρηστόν τε καὶ παρὰ φύσιν, οὕτω καὶ τοῦ φλέγματος, ὅσον μὲν ἂν ᾖ γλυκύ, χρηστὸν εἶναι τοῦτο τῷ ζῴῳ καὶ κατὰ φύσιν, ὅσον δʼ ὀξὺ καὶ ἁλμυρὸν ἐγένετο, τὸ μὲν ὀξὺ τελέως ἠπεπτῆσθαι, τὸ δʼ ἁλμυρὸν διασεσῆφθαι. τελείαν δʼ ἀπεψίαν φλέγματος ἀκούειν χρὴ τὴν τῆς δευτέρας πέψεως δηλονότι τῆς ἐν φλεψίν· οὐ γὰρ δὴ τῆς γε πρώτης τῆς κατὰ τὴν κοιλίαν·

It seems to me that I have made enough reference to what has been said regarding the genesis and destruction of humours by Hippocrates, Plato, Aristotle, Praxagoras, and Diocles, and many others among the Ancients; I did not deem it right to transport the whole of their final pronouncements into this treatise. I have said only so much regarding each of the humours as will stir up the reader, unless he be absolutely inept, to make himself familiar with the writings of the Ancients, and will help him to gain more easy access to them. In another treatise I have written on the humours according to Praxagoras, to Praxagoras, son of authority Nicarchus; although this authority makes as many as ten humours, not including the blood (the blood itself being an eleventh), this is not a departure from the teaching of Hippocrates; for Praxagoras divides into species and varieties the humours which Hippocrates first mentioned, with the demonstration proper to each.

ἢ οὐδʼ ἂν ἐγεγένητο τὴν ἀρχὴν χυμός, εἰ καὶ ταύτην διεπεφεύγει. ταῦτʼ ἀρκεῖν μοι δοκεῖ περὶ γενέσεώς τε καὶ διαφθορᾶς χυμῶν ὑπομνήματʼ εἶναι τῶν Ἱπποκράτει τε καὶ Πλάτωνι καὶ Ἀριστοτέλει καὶ Πραξαγόρόρᾳ καὶ Διοκλεῖ καὶ πολλοῖς ἄλλοις τῶν παλαιῶν εἰρημένων· οὐ γὰρ ἐδικαίωσα πάντα μεταφέρειν εἰς τόνδε τὸν λόγον τὰ τελέως ἐκείνοις γεγραμμένα. τοσοῦτον δὲ μόνον ὑπὲρ ἑκάστου εἶπον, ὅσον ἐξορμήσει τε τοὺς ἐντυγχάνοντας, εἰ μὴ παντάπασιν εἶεν σκαιοί, τοῖς τῶν παλαιῶν ὁμιλῆσαι γράμμασι καὶ τὴν εἰς τὸ Ῥᾷον αὐτοῖς συνεῖναι βοήθειαν παρέξει. γέγραπται δέ που καὶ διʼ ἑτέρου λόγου περὶ τῶν κατὰ Πραξαγόραν τὸν Νικάρχου χυμῶν. εἰ γὰρ καὶ ὅτι μάλιστα δέκα ποιεῖ χωρὶς τοῦ αἵματος, ἑνδέκατος γὰρ ἂν εἴη χυμὸς αὐτὸ τὸ αἷμα, τῆς Ἱπποκράτους οὐκ ἀποχωρεῖ διδασκαλίας.

Those, then, are to be praised who explain the points which have been duly mentioned, as also those who add what has been left out; for it is not possible for the same man to make both a beginning and an end. Those, on the other hand, deserve censure who are so impatient that they will not wait to learn any of the things which have been duly mentioned, as do also those who are so ambitious that, in their lust after novel doctrines, they are always attempting some fraudulent sophistry, either purposely neglecting certain subjects, as Erasistratus does in the case of the humours, or unscrupulously attacking other people, as does this same writer, as well as many of the more recent authorities.

ἀλλʼ εἰς εἴδη τινὰ καὶ διαφορὰς τέμνει τοὺς ὑπʼ ἐκείνου πρώτου πάντων ἅμα ταῖς οἰκείαις ἀποδείξεσιν εἰρημένους χυμούς. ἐπαινεῖν μὲν οὖν χρὴ τούς τʼ ἐξηγησαμένους τὰ καλῶς εἰρημένα καὶ τοὺς εἴ τι παραλέλειπται προστιθέντας· οὐ γὰρ οἷόν τε τὸν αὐτὸν ἄρξασθαί τε καὶ τελειῶσαι· μέμφεσθαι δὲ τοὺς οὕτως ἀταλαιπώρους, ὡς μηδὲν ὑπομένειν μαθεῖν τῶν ὀρθῶς εἰρημένων, καὶ τοὺς εἰς τοσοῦτον φιλοτίμους, ὥστʼ ἐπιθυμίᾳ νεωτέρων δογμάτων ἀεὶ πανουργεῖν τι καὶ σοφίζεσθαι, τὰ μὲν ἑκόντας παραλιπόντας, ὥσπερ Ἐρασίστρατος ἐπὶ τῶν χυμῶν ἐποίησε, τὰ δὲ πανούργως ἀντιλέγοντας, ὥσπερ αὐτός θʼ οὗτος καὶ ἄλλοι πολλοὶ τῶν νεωτέρων.

But let this discussion come to an end here, and I shall add in the third book all that remains.

ἀλλʼ οὗτος μὲν ὁ λόγος ἐνταυθοῖ τελευτάτω, τὸ δʼ ὑπόλοιπον ἅπαν ἐν τῷ τρίτῳ προσθήσω.
