[¶0] 1. MEN’S heads are by no means all like to one another, nor are the sutures of the head of all men constructed in the same form. Thus, whoever has a prominence in the anterior part of the head (by prominence is meant the round protuberant part of the bone which projects beyond the rest of it), in him the sutures of the head take the form of the Greek letter tau, T; for the head has the shorter line running transverse before the prominence, while the other line runs through the middle of the head, all the way to the neck. But whoever has the prominence in the back part of the head, in him the sutures are constructed in quite the opposite form to the former; for in this case the shorter line runs in front of the prominence, while the longer runs through the middle all along to the forehead. But whoever has a prominence of the head both before and behind, in him the sutures resemble the Greek letter eta E; for the long lines of the letter run transverse before each prominence while the short one runs through the middle and terminates in the long lines. But whoever has no prominence on either part he has the sutures of the head resembling the Greek letter chi; for the one line comes transverse to the temple while the other passes along the middle of the head. The bone at the middle of the head is double, the hardest and most compact part being the upper portion, where it is connected with the skin, and the lowest, where it is connected with the meninx (dura mater); and from the uppermost and lowermost parts the bone gradually becomes softer and less compact, till you come to the diploe. The diploe is the most porous, the softest, and most cavernous part. But the whole bone of the head, with the, exception of a small portion of the uppermost and lowermost portions of it, is like a sponge; and the bone has in it many juicy substances, like caruncles; and if one will rub them with the fingers, some blood will issue from them. There are also in the bone certain very slender and hollow vessels full of blood. So it is with regard to hardness, softness, and porosity.

> Greek: 1. 1. τῶν ἀνθρώπων αἱ κεφαλαὶ οὐδὲν ὁμοίως σφίσιν αὐταῖς, οὐδὲ αἱ ῤαφαὶ τῆς κεφαλῆς πάντων κατὰ ταὐτὰ πεφύκασιν. ἀλλʼ ὅστις μὲν ἔχει ἐκ τοῦ ἔμπροσθεν τῆς κεφαλῆς προβολὴν (ἡ δὲ προβολή ἐστι τὸ τοῦ ὀστέου ἐξέχον στρογγύλον παρὰ τὸ ἄλλo), τουτέου εἰσὶν αἱ ῤαφαὶ πεφυκυῖαι ἐν τῇ κεφαλῇ, ὡς γράμμα τὸ ταῦ, Τ, γράφεται· τὴν μὲν γὰρ βραχυτέρην γραμμὴν ἔχει πρὸ τῆς προβολῆς ἐπικαρσίην πεφυκυῖαν· τὴν δʼ ἑτέρην γραμμὴν ἔχει διὰ μέσης τῆς κεφαλῆς κατὰ μῆκος πεφυκυῖαν ἐς τὸν τράχηλον αἰεί. ὅστις δʼ ὄπισθεν τῆς κεφαλῆς τὴν προβολὴν ἔχει, αἱ ῤαφαὶ τουτέῳ πεφύκασι τἀναντία ἢ τῷ προτέρῳ· ἡ μὲν γὰρ βραχυτέρη γραμμὴ πρὸ τῆς προβολῆς πέφυκεν ἐπικαρσίη· ἡ δὲ μακροτέρη διὰ μέσης τῇς κεφαλῆς πέφυκε κατὰ μῆκος ἐς τὸ μέτωπον αἰεί. ὅστις δὲ ἀμφοτέρωθεν τῆς κεφαλῆς προβολὴν ἔχει, ἐκ τε τοῦ ἔμπροσθεν καὶ ἐκ τοῦ ὄπισθεν, τουτέῳ αἱ ῤαφαί εἰσιν ὁμοίως πεφυκυῖαι ὡς γράμμα τὸ ἦτα,, γράφεται· πεφύκασι δὲ τῶν γραμμέων αἱ μὲν μακραὶ, πρὸ τῆς προβολῆς ἑκατέρης ἐπικάρσιαι πεφυκυῖαι· ἡ δὲ βραχείη διὰ μέσης τῆς κεφαλῆς κατὰ μῆκος πρὸς ἑκατέρην τελευτῶσα τὴν μακρὴν γραμμήν. ὅστις δὲ μηδʼ ἑτέρωθι μηδεμίαν προβολὴν ἔχει, οὗτος ἔχει τὰς ῤαφὰς τῆς κεφαλῆς, ὡς γράμμα τὸ χῖ, Χ, γράφεται· πεφύκασι δὲ αἱ γραμμαὶ, ἡ μὲν ἑτέρη ἐπικαρσίη πρὸς τὸν κρόταφον ἀφίκουσα· ἡ δὲ ἑτέρη, κατὰ μῆκος διὰ μέσης τῆς κεφαλῆς. Δίπλοον δʼ ἐστὶ τὸ ὀστέον κατὰ μέσην τὴν κεφαλήν· σκληρότατον δὲ καὶ πυκνότατον αὐτέου πέφυκεν τό τε ἀνώτατον, ᾗ ἡ ὁμοχροίη τοῦ ὀστέου ἡ ὑπὸ τῇ σαρκὶ, καὶ τὸ κατώτατον τὸ πρὸς τῇ μήνιγγι, ᾗ ἡ ὁμοχροίη τοῦ ὀστέου ἡ κάτω· ἀποχωρέον δὲ ἀπὸ τοῦ ἀνωτάτου ὀστέου καὶ τοῦ κατωτάτου, ἀπὸ τῶν σκληροτάτων καὶ πυκνοτάτων ἐπὶ τὸ μαλθακώτερον καὶ ἧσσον πυκνὸν καὶ ἐπικοιλότερον ἐς τὴν διπλόην αἰεί. ἡ δὲ διπλόη κοιλότατον καὶ μαλθακώτατον καὶ μάλιστα σηραγγῶδές ἐστιν. ἔστι δὲ καὶ πᾶν τὸ ὀστέον τῆς κεφαλῆς, πλὴν κάρτα ὀλίγου τοῦ τε ἀνωτάτου καὶ τοῦ κατωτάτου, σπόγγῳ ὅμοιον· καὶ ἔχει τὸ ὀστέον ἐν ἑωυτῷ ὁκοῖα σαρκία πολλὰ καὶ ὑγρὰ, καὶ εἴ τις αὐτὰ διατρίβοι τοῖσι δακτύλοισιν, αἷμα ἂν διαγίγνοιτο ἐξ αὐτέων. ἔνι δʼ ἐν τῷ ὀστέῳ καὶ φλέβια λεπτότερα καὶ κοιλότερα, αἵματος πλέα. σκληρότητος μὲν οὖν καὶ μαλθακότητος καὶ κοιλότητος ὧδε ἔχει.

[¶1] 2. In respect to thickness and thinness; the thinnest and weakest part of the whole head is the part about the bregma; and the bone there has the smallest and thinnest covering of flesh upon it, and the largest proportion of brain is situated in that region of the head. And hence it happens that from similar or even smaller wounds and instruments, when a person is wounded to the same or a less degree, the bone of the head there is more contused, fractured, and depressed; and that injuries there are more deadly and more difficult to cure; and it is more difficult to save one’s life in injuries there than in any other part of the head; that from having sustained a similar or even a less wound a man will die, and that, too, in a shorter space of time than from a wound in any other part of the head. For the brain about the bregma feels more quickly and strongly any mischief that may occur to the flesh or the bone; for the brain about the bregma is in largest quantity, and is covered by the thinnest bone and the least flesh. Of the other portions, the weakest is that about the temples; for it is the conjunction of the lower jaw with the cranium, and there is motion there up and down as at a joint; and the organ of hearing is near it; and further, a hollow and important vein runs along the temple. But the whole bone of the head behind the vertex and the ear is stronger than the whole anterior part, and the bone itself has a larger and deeper covering of flesh upon it. And hence it follows, that when exposed to the same or even greater injuries from instruments of the same or greater size, the bone is less liable to be fractured and depressed than elsewhere; and that in a fatal accident the patient will live longer when the wound is in the posterior part of the head than when elsewhere; and that pus takes longer time to form and penetrate through the bone to the brain, owing to the thickness of the bone; and moreover, as there is less brain in that part of the head, more persons who are wounded in the back part of the head escape than of those who wounded in the anterior part. And in fatal cases, a man will survive longer in winter than in summer, whatever be the part of the head in which the wound is situated.

> Greek: 2. 2. παχύτητι δὲ καὶ λεπτότητι, ξυμπάσης τῆς κεφαλῆς τὸ ὀστέον λεπτότατόν ἐστιν καὶ ἀσθενέστατον τὸ κατὰ βρέγμα, καὶ σάρκα ὀλιγίστην καὶ λεπτοτάτην ἔχει ἐφʼ ἑωυτέῳ ταύτῃ τῆς κεφαλῆς τὸ ὀστέον, καὶ ὁ ἐγκέφαλος κατὰ τοῦτο τῆς κεφαλῆς πλεῖστος ὕπεστιν. καὶ δὴ, ὅτι οὕτω ταῦτα ἔχει, τῶν τε τρωσίων καὶ τῶν βελέων ἴσων τε ἐόντων κατὰ μεγέθος, καὶ ἐλασσόνων, καὶ ὁμοίως τε τρωθεὶς καὶ ἧσσον, τὸ ὀστέον ταύτῃ τῆς κεφαλῆς φλᾶταί τε μᾶλλον καὶ ῤήγνυται, καὶ ἔσω ἐσφλᾶται, καὶ θανασιμώτερά ἐστι καὶ χαλεπώτερα ἰητρεύεσθαί τε καὶ ἐκφυγγάνειν τὸν θάνατον ταύτῃ ἤπου ἄλλοθι τῆς κεφαλῆς· ἐξίσων τε ἐόντων τῶν τρωμάτων καὶ ἡσσόνων, καὶ ὁμοίως τε τρωθεὶς καὶ ἧσσον, ἀποθνήσκει ὁ ἄνθρωπος, ὅταν καὶ ἄλλως μέλλῃ ἀποθανεῖσθαι ἐκ τοῦ τρώματος, ἐν ἐλάσσονι χρόνῳ ὁ ταύτῃ ἔχων τὸ τρῶμα τῆς κεφαλῆς, ἤπου ἄλλοθι. ὁ γὰρ ἐγκέφαλος τάχιστά τε καὶ μάλιστα κατὰ τὸ βρέγμα αἰσθάνεται τῶν κακῶν τῶν γιγνομένων ἔν τε τῇ σαρκὶ καὶ τῷ ὀστέῳ· ὑπὸ λεπτοτάτῳ γὰρ ὀστέῳ ἐστὶ ταύτῃ ὁ ἐγκέφαλος καὶ ὀλιγίστῃ σαρκὶ, καὶ ὁ πλεῖστος ἐγκέφαλος ὑπὸ τῷ βρέγματι κεῖται. τῶν δὲ ἄλλων τὸ κατὰ τοὺς κροτάφους ἀσθενέστατόν ἐστιν· ξυμβολή τε γὰρ τῆς κάτω γνάθου πρὸς τὸ κρανίον, καὶ κίνησις ἔνεστιν ἐν τῷ κροτάφῳ ἄνω καὶ κάτω ὥσπερ ἄρθρου· καὶ ἡ ἀκοὴ πλησίον γίγνεται αὐτέου, καὶ φλὲψ διὰ τοῦ κροτάφου τέταται κοίλη τε καὶ ἰσχυρή. ἰσχυρότερον δʼ ἐστὶ τῆς κεφαλῆς τὸ ὀστέον ἅπαν τὸ ὄπισθεν τῆς κορυφῆς καὶ τῶν οὐάτων, ἢ ἅπαν τὸ πρόσθεν, καὶ σάρκα πλέονα καὶ βαθυτέρην ἐφʼ ἑωυτέῳ ἔχει τοῦτο τὸ ὀστέον. καὶ δὴ, τουτέων οὕτως ἐχόντων ὑπὸ τῶν τε τρωσίων καὶ τῶν βελέων ἴσων ἐόντων καὶ ὁμοίων, καὶ μεζόνων, καὶ ὁμοίως τιτρωσκόμενος καὶ μᾶλλον, ταύτῃ τῆς κεφαλῆς τὸ ὀστέον ἧσσον ῤήγνυται καὶ φλᾶται ἔσω· κἢν μέλλῃ ὥνθρωπος ἀποθνήσκειν καὶ ἄλλως ἐκ τοῦ τρώματος, ἐν τῷ ὄπισθεν τῆς κεφαλῆς ἔχων τὸ τρῶμα, ἐν πλέονι χρόνῳ ἀποθανεῖται· ἐν πλέονι γὰρ χρόνῳ τὸ ὀστέον ἐμπυΐσκεταί τε καὶ διαπυΐσκεται κάτω ἐπὶ τὸν ἐγκέφαλον διὰ τὴν παχύτητα τοῦ ὀστέου, καὶ ἐλάσσων ταύτῃ τῆς κεφαλῆς ὁ ἐγκέφαλος ὕπεστι, καὶ πλέονες ἐκφυγγάνουσι τὸν θάνατον τῶν ὄπισθεν τιτρωσκομένων τῆς κεφαλῆς ὡς ἐπιτοπολὺ, ἢ τῶν ἔμπροσθεν. καὶ ἐν χειμῶνι πλέονα χρόνον ζῇ ὥνθρωπος ἢ ἐν θέρει, ὅστις καὶ ἄλλως μέλλει ἀποθανεῖσθαι ἐκ τοῦ τρώματος, ὁκουοῦν τῆς κεφαλῆς ἔχων τὸ τρῶμα.

[¶2] 3. As to the haedrae (dints or marks?) of sharp and light weapons, when they take place in the bone without fissure, contusion, or depression inwards (and these take place equally in the anterior and posterior part of the head), death, when it does occur, does not properly result from them. A suture appearing in a wound, when the bone is laid bare, on whatever part of the head the wound may have been inflicted, is the weakest point of the head to resist a blow or a weapon, when the weapon happens to be impinged into the suture itself; but more especially when this occurs in the bregma at the weakest part of the head, and the sutures happen to be situated near the wound, and the weapon has hit the sutures themselves.

> Greek: 3. 3. αἱ δὲ ἕδραι τῶν βελέων τῶν ὀξέων καὶ κουφοτέρων, αὐταὶ ἐπὶ σφῶν αὐτέων γινόμεναι ἐν τῷ ὀστέῳ, ἄνευ ῤωγμῆς τε καὶ φλάσιος, ἢ ἔσω ἐσφλάσιος (αὗται δὲ γίνονται ὁμοίως ἔν τε τῷ ἔμπροσθεν τῆς κεφαλῆς, καὶ ἐν τῷ ὄπισθεν), ἐκ τουτέων ὁ θάνατος οὐ γίνεται κατά γε δίκην, οὐδʼ ἢν γένηται. Ῥαφὴ δὲ ἐν ἕλκει φανεῖσα, ὀστέου ψιλωθέντος, πανταχοῦ τῆς κεφαλῆς τοῦ ἕλκεος γενομένου, ἀσθενέστατον γίγνεται τῇ τρώσει καὶ τῷ βέλει ἀντέχειν, εἰ τύχοι τὸ βέλος ἐς αὐτὴν τὴν ῤαφὴν στηριχθέν· πάντων δὲ μάλιστα ἐν τῷ βρέγματι γενόμενον κατὰ τὸ ἀσθενέστατον τῆς κεφαλῆς, καὶ αἱ ῤαφαὶ εἰ τύχοιεν ἐοῦσαι περὶ τὸ ἕλκος, καὶ τὸ βέλος αὐτέων τύχοι τῶν ῤαφῶν.

[¶3] 4. The bone in the head is liable to be wounded in the following modes, and there are many varieties in each of these modes of fracture: When a wounded bone breaks, in the bone comprehending the fissure, contusion necessarily takes place where the bone is broken; for an instrument that breaks the bone occasions a contusion thereof more or less, both at the fracture and in the parts of the bone surrounding the fracture. This is the first mode. But there are all possible varieties of fissures; for some of them are fine, and so very fine that they cannot be discovered, either immediately after the injury, or during the period in which it would be of use to the patient if this could be ascertained. And some of these fissures are thicker and wider, certain of them being very wide. And some of them extend to a greater, and some to a smaller, distance. And some are more straight, nay, completely straight; and some are more curved, and that in a remarkable degree. And some are deep, so as to extend downwards and through the whole bone; and some are less so, and do not penetrate through the whole bone.

> Greek: 4. 4. τιτρώσκεται δὲ ὀστέον τὸ ἐν τῇ κεφαλῇ τοσούσδε τρόπους· τῶν δὲ τρόπων ἑκάστου πλέονες ἰδέαι γίγνονται τοῦ κατήγματος ἐν τῇ τρώσει. ὀστέον ῤήγνυται τιτρωσκόμενον, καὶ τῷ περιέχοντι ὀστέῳ τὴν ῤωγμὴν, ἀνάγκη φλάσιν προσγίγνεσθαι, ἤνπερ ῤαγῇ· τῶν γὰρ βελέων ὅ τι περ ῤήγνυσι τὸ ὀστέον, τὸ αὐτὸ τοῦτο καὶ φλᾷ τὸ ὀστέον ἢ μᾶλλον, ἢ ἧσσον, αὐτό τε ἐν ᾧπερ καὶ ῤήγνυσι τὴν ῤωγμὴν, καὶ τὰ περιέχοντα ὀστέα τὴν ῤώγμήν· εἷς οὗτος τρόπος. ἰδέαι δὲ ῤωγμέων παντοῖαι γίγνονται· καὶ γὰρ λεπτότεραί τε καὶ λεπταὶ πάνυ, ὥστε οὐ καταφανέες γίγνονται ἔστιν αἳ τῶν ῤωγμέων, οὔτε αὐτίκα μετὰ τὴν τρῶσιν, οὔτʼ ἐν τῇσιν ἡμέρῃσιν, ἐν ᾗσιν ἂν καὶ πλέον ὄφελος γένοιτο ἐκ τούτου τῷ ἀνθρώπῳ· αἱ δʼ αὖ παχύτεραί τε καὶ εὐρύτεραι ῤήγνυνται τῶν ῤωγμέων· ἔνιαι δὲ καὶ πάνυ εὐρέαι. ἔστι δὲ αὐτέων καὶ αἳ μὲν ἐπὶ μακρότερον ῤήγνυνται, αἳ δὲ ἐπὶ βραχύτερον. καὶ αἱ μὲν ἰθύτεραί τε καὶ ἰθεῖαι πάνυ, αἱ δὲ καμπυλώτεραί τε καὶ καμπύλαι· καὶ βαθύτεραί τε ἐς τὸ κάτω καὶ διὰ παντὸς τοῦ ὀστέου, καὶ ἧσσον βαθεῖαι ἐς τὸ κάτω, καὶ οὐ διὰ παντὸς τοῦ ὀστέου.

[¶4] 5. But a bone may be contused, and yet remain in its natural condition without any fracture in it; this is the second mode. And there are many varieties of contusion; for they occur to a greater or less degree, and to a greater depth, so as sometimes to extend through the whole bone; or to a less depth, so as not to extend through the whole bone; and to a greater and smaller length and breadth. But it is not possible to recognize any of these varieties by the sight, so as to determine their form and extent; neither, indeed, is it visible to the eyes when any mischief of this kind takes place, and immediately after the injury, whether or not the bone has been actually bruised, as is likewise the case with certain fractures at a distance from the seat of injury.

> Greek: 5. 5. Φλασθείη δʼ ἂν τὸ ὀστέον μένον ἐν τῇ ἑωυτοῦ φύσει, καὶ ῤωγμὴ τῇ φλάσει οὐκ ἂν προσγένοιτο ἐν τῷ ὀστέῳ οὐδεμία· δεύτερος οὗτος τρόπος. ἰδέαι δὲ τῆς φλάσιος πλείους γίγνονται· καὶ γὰρ μᾶλλόν τε καὶ ἧσσον φλᾶται, καὶ ἐς βαθύτερόν τε καὶ διὰ παντὸς τοῦ ὀστέου, καὶ ἧσσον ἐς βαθὺ, καὶ οὐ διὰ παντὸς τοῦ ὀστέου, καὶ ἐπὶ πλέον τε καὶ ἔλασσον μήκεός τε καὶ πλατύτητος. ἀλλʼ οὐ τουτέων τῶν ἰδεῶν οὐδεμίαν ἐστὶν ἰδόντα τοῖσιν ὀφθαλμοῖσι γνῶναι, ὁκοίη τίς ἐστι τὴν ἰδέην, καὶ ὁκόσητις τις τὸ μέγεθος· οὐδὲ γὰρ εἰ πέφλασται, ἢ μὴ πέφλασται, ἐόντων πεφλασμένων καὶ τοῦ κακοῦ γεγενημένου, γίγνεται τοῖσιν ὀφθαλμοῖσι καταφανὲς ἰδεῖν αὐτίκα μετὰ τὴν τρῶσιν, ὥσπερ οὐδὲ τῶν ῤωγμέων ἔνιαι ἑκὰς ἐοῦσαι.

[¶5] 6. And the bone being fractured, is sometimes depressed inwards from its natural level along with the fractures, otherwise there would be no depression; for the depressed portion being fractured and broken off, is pushed inwards, while the rest of the bone remains in its natural position; and in this manner a fracture is combined with the depression. This is the third mode. There are many varieties of depression, for it may comprehend a greater and a small extent of bone, and may either be to a greater depth, or less so, and more superficial.

> Greek: 6. 6. καὶ ἐῤῥωγότος τοῦ ὀστέου, ἐσφλᾶται τὸ ὀστέον ἐκ τῆς φύσιος τῆς ἑωυτοῦ ἔσω σὺν ῤωγμῇσιν· ἄλλως γὰρ οὐκ ἂν ἐσφλασθείη· τὸ γὰρ ἐσφλώμενον, ἀποῤῥηγνύμενόν τε καὶ καταγνύμενον, ἐσφλᾶται ἔσω ἀπὸ τοῦ ἄλλου ὀστέου μένοντος ἐν τῇ φύσει τῇ ἑωυτοῦ· καὶ δὴ οὕτω ῤωγμὴ ἂν προσείη τῇ ἐσφλάσει· τρίτος οὗτος τρόπος. ἐσφλᾶται δὲ τὸ ὀστέον πολλὰς ἰδέας· καὶ γὰρ ἐπὶ πλέον τοῦ ὀστέου καὶ ἐπʼ ἔλασσον, καὶ μᾶλλόν τε καὶ ἐς βαθύτερον κάτω, καὶ ἧσσόν τε καὶ ἐπιπολαιότερον.

[¶6] 7. When a hedra, or dint of a weapon, takes place in a bone, there may be a fracture combined with it; and provided there be a fracture, contusion must necessarily be joined, to a greater or less extent, in the seat of the dint and fracture, and in the bone which comprehends them. This is the fourth mode. And there may be a hedra, or indentation of the bone, along with contusion of the surrounding bone, but without any fracture either in the hedra or in the contusion inflicted by the weapon. But the indentation of a weapon takes place in a bone, and is called hedra, when the bone remaining in its natural state, the weapon which struck against the bone leaves its impression on the part which it struck. In each of these modes there are many varieties, with regard to the contusion and fracture, if both these be combined with the hedra, or if contusion alone, as it has been already stated that there are many varieties of contusion and fracture. And the hedra, or dint, of itself may be longer and shorter, crooked, straight, and circular; and there are many varieties of this mode, according to the shape of the weapon; and they may be more or less deep, and narrower or broader, and extremely broad. When a part is cleft, the cleft or notch which occurs in the bone, to whatever length or breadth, is a hedra, if the other bones comprehending the cleft remain in their natural position, and be not driven inwards; for in this case it would be a depression, and no longer a hedra.

> Greek: 7. 7. καὶ ἕδρης γενομένης ἐν τῷ ὀστέῳ βέλεος, προσγένοιτο ἂν ῤωγμὴ τῇ ἑδραίῃ· φλάσιν προσγενέσθαι ἀναγκαῖόν ἐστιν, ἢ μᾶλλον, ἢ ἧσσον, ἤνπερ καὶ ῤωγμὴ προσγένηται, ἐνθάπερ ἡ ἕδρη ἐγένετο καὶ ἡ ῤωγμὴ, καὶ ἐν τῷ ὀστέῳ τῷ περιέχοντι τήν τε ἕδρην καὶ τὴν ῤωγμήν· τέταρτος οὗτος τρόπος. καὶ ἕδρη μὲν ἂν γένοιτο, φλάσιν ἔχουσα τοῦ ὀστέου περὶ αὐτὴν, ῤωγμὴ δὲ οὐκ ἂν προσγένοιτο τῇ ἕδρῃ καὶ τῇ φλάσει ὑπὸ τοῦ βέλεος. καὶ ἕδρη δὲ τοῦ βέλεος γίγνεται ἐν τῷ ὀστέῳ· ἕδρη δὲ καλέεται, ὅταν, μένον τὸ ὀστέον ἐν τῇ ἑωυτοῦ φύσει, τὸ βέλος στηρίξαν ἐς τὸ ὀστέον δῆλον ποιήσῃ ὅκου ἐστήριξεν. ἐν δὲ τῷ τρόπῳ ἑκάστῳ πλέονες ἰδέαι γίγνονται· καὶ περὶ μὲν φλάσιός τε καὶ ῤωγμῆς, ἢν ἄμφω ταῦτα προσγένηται τῇ ἕδρῃ, καὶ ἢν φλάσις μούνη γένηται, ἤδη πέφρασται, ὅτι πολλαὶ ἰδέαι γίνονται καὶ τῆς φλάσιος καὶ τῆς ῤωγμῆς. ἡ δὲ ἕδρη αὐτὴ ἐφʼ ἑωυτῆς γίνεται, μακροτέρη καὶ βραχυτέρη ἐοῦσα, καὶ καμπυλωτέρη, καὶ ἰθυτέρη, καὶ κυκλοτερής· καὶ πολλαὶ ἄλλαι ἰδέαι τοῦ τοιουτέου τρόπου, ὁκοῖον ἄν τι καὶ τὸ σχῆμα τοῦ βέλεος ᾖ· αὐταὶ δὲ καὶ βαθύτεραι τὸ κάτω καὶ μᾶλλον καὶ ἧσσον, καὶ στενότεραι, καὶ εὐρύτεραι, καὶ πάνυ εὐρέαι. Ἣ διακέκοπται διακοπὴ δʼ, ὁκοσητισοῦν γιγνομένη μήκεός τε καὶ εὐρύτητος ἐν τῷ ὀστέῳ, ἕδρη ἐστὶν, ἢν τὰ ἄλλα ὀστέα τὰ περιέχοντα τὴν διακοπὴν μένῃ ἐν τῇ φύσει τῇ ἑωυτέων, καὶ μὴ ξυνεσφλᾶται τῇ διακοπῇ ἔσω ἐκ τῆς φύσιος τῆς ἑωυτέων· οὕτω δʼ ἔσφλασις ἂν εἴη, καὶ οὐκ ἔτι ἕδρη.

[¶7] 8. A bone may be injured in a different part of the head from that on which the person has received the wound, and the bone has been laid bare. This is the fifth mode. And for this misfortune, when it occurs, there is no remedy; for when this mischief takes place, there is no means of ascertaining by any examination whether or not it has occurred, or on what part of the head.

> Greek: 8. 8. ὀστέον τιτρώσκεται ἄλλῃ τῆς κεφαλῆς, ἢ ᾗ τὸ ἕλκος ἔχει ὥνθρωπος, καὶ τὸ ὀστέον ἐψιλώθη τῆς σαρκός· πέμπτος οὗτος τρόπος. καὶ ταύτην τὴν ξυμφορὴν, ὅταν γένηται, οὐκ ἂν ἔχοις ὠφελῆσαι οὐδέν. οὐδὲ γὰρ, εἰ πέπονθε τὸ κακὸν τοῦτο, οὐκ ἔστιν ὅκως χρὴ αὐτὸν ἐξελέγξαντα εἰδέναι εἰ πέπονθε τὸ κακὸν τοῦτο ὥνθρωπος, οὐδʼ ὅκοι τῆς κεφαλῆς.

[¶8] 9. Of these modes of fracture, the following require trepanning: the contusion, whether the bone be laid bare or not; and the fissure, whether apparent or not. And if, when an indentation (hedra) by a weapon takes place in a bone it be attended with fracture and contusion, and even if contusion alone, without fracture, be combined with the indentation, it requires trepanning. A bone depressed from position rarely requires trepanning; and those which are most pressed and broken require trepanning the least; neither does an indentation (hedra) without fracture and contusion require trepanning; nor does a notch, provided it is large and wide; for a notch and a hedra are the same.

> Greek: 9. 9. τούτων τῶν τρόπων τῆς κατήξιος ἐς πρίσιν ἀφήκει, ἥ τε φλάσις ἡ ἀφανὴς ἰδεῖν, καὶ ἤν πως τύχῃ φανερὴ γενομένη, καὶ ἡ ῤωγμὴ ἡ ἀφανὴς ἰδεῖν, καὶ ἢν φανερὴ ᾖ. καὶ ἢν, ἕδρης γενομένης τοῦ βέλεος ἐν τῷ ὀστέῳ, προσγένηται ῤωγμὴ καὶ φλάσις τῇ ἕδρῃ, καὶ ἢν φλάσις μοῦνον προσγένηται ἄνευ ῤωγμῆς τῇ ἕδρῃ, καὶ αὕτη ἐς πρίσιν ἀφήκει. τὸ δʼ ἔσω ἐσφλώμενον ὀστέον ἐκ τῆς φύσιος τῆς ἑωυτοῦ, ὀλίγα τῶν πολλῶν πρίσιος προσδεῖται· καὶ τὰ μάλιστα ἐσφλασθέντα καὶ μάλιστα καταῤῥαγέντα, ταῦτα πρίσιος ἥκιστα κέχρηται· οὐδὲ ἕδρη αὐτὴ ἐφʼ ἑωυτῆς γενομένη ἄτερ ῤωγμῆς καὶ φλάσιος, οὐδὲ αὐτὴ πρίσιος δεῖται· οὐδʼ ἡ διακοπὴ, ἢν μεγάλη καὶ εὐρέη, οὐδʼ αὐτή· διακοπὴ γὰρ καὶ ἕδρη τωὐτόν ἐστιν.

[¶9] 10. In the first place, one must examine the wounded person, in what part of the head the wound is situated, whether in the stronger or weaker parts; and ascertain respecting the hairs about the wound, whether they have been cut off by the instrument, and have gone into the wound; and if so, one should declare that the bone runs the risk of being denuded of flesh, and of having sustained some injury from the weapon. These things one should say from a distant inspection, and before laying a hand on the man; but on a close examination one should endeavor to ascertain clearly whether the bone be denuded of flesh or not; and if the denuded bone be visible to the eyes, this will be enough; but otherwise an examination must be made with the sound. And if you find the bone denuded of the flesh, and not safe from the wound, you must first ascertain the state of the bone, and the extent of the mischief, and of what assistance it stands in need. One should also inquire of the wounded person how and in what way he sustained the injury; and if it be not apparent whether the bone has sustained an injury or not, it will be still more necessary, provided the bone be denuded, to make inquiry how the wound occurred, and in what manner; for when contusions and fractures existin the bone, but are not apparent, we must ascertain, in the first place from the patient’s answers, whether or not the bone has sustained any such injuries, and then find out the nature of the case by word and deed, with the exception of sounding. For sounding does not discover to us whether the bone has sustained any of these injuries or not; but sounding discovers to us an indentation inflicted by a weapon, and whether a bone be depressed from its natural position, and whether the bone be strongly fractured; all which may also be ascertained visibly with the eyes.

[¶10] 11. And a bone sustains fractures, either so fine as to escape the sight, or such as are apparent, and contusions which are not apparent, and depression from its natural position, especially when one person is intentionally wounded by another, or when, whether intentionally or not, a blow or stroke is received from an elevated place, and if the instrument in the hand, whether used in throwing or striking, be of a powerful nature, and if a stronger person wound a weaker. Of those who are wounded in the parts about the bone, or in the bone itself, by a fall, he who falls from a very high place upon a very hard and blunt object is in most danger of sustaining a fracture and contusion of the bone, and of having it depressed from its natural position; whereas he that falls upon more level ground, and upon a softer object, is likely to suffer less injury in the bone, or it may not be injured at all. Of those instruments which, falling upon the head, wound the parts about the bone, or the bone itself, that which falls from a very high place, and the least on a level with the person struck, and which is at the same time very hard, very blunt, and very heavy, and which is the least light, sharp, and soft, such an instrument would occasion a fracture and contusion of the bone. And there is most danger that the bone may sustain these injuries, under such circumstances, when the wound is direct and perpendicular to the bone, whether struck from the hand or from a throw, or when any object falls upon the person, or when he is wounded by falling, or in whatever way the bone sustains a direct wound from this instrument. Those weapons which graze the bone obliquely are less apt to fracture, contuse, or depress the bone, even when the bone is denuded of flesh; for in some of those wounds thus inflicted the bone is not laid bare of the flesh. Those instruments more especially produce fractures in the bone, whether apparent or not, and contusions, and inward depression of the bone, which are rounded, globular, smooth on all sides, blunt, heavy, and hard; and such weapons bruise, compress, and pound the flesh; and the wounds inflicted by such instruments, whether obliquely or circularly, are round, and are more disposed to suppurate, and to have a discharge, and take longer time to become clean; for the flesh which has been bruised and pounded must necessarily suppurate and slough away. But weapons of an oblong form, being, for the most part, slender, sharp, and light, penetrate the flesh rather than bruise it, and the bone in like manner; and such an instrument may occasion a hedra and a cut (for a hedra and a cut are same thing); but weapons of this description do not produce contusions, nor fractures, nor depressions inwardly. And in addition the appearances in the bone, which you call detect by the sight, you should make inquiry as to all these particulars (for they are symptoms of a greater or less injury), whether the wounded person was stunned, and whether darkness was diffused over his eyes, and whether he had vertigo, and fell to the ground.

[¶11] 12. When the bone happens to be denuded of flesh by the weapon, and when the wound occurs upon the sutures, it is difficult to distinguish the indentation (hedra) of a weapon which is clearly recognized in other parts of the bone, whether it exist or not, and especially if the hedra be seated in the sutures themselves. For the suture being rougher than the rest of the bone occasions confusion, and it is not clear which is the suture, and which the mark inflicted by the instrument, unless the latter (hedra) be large. Fracture also for the most part is combined with the indentation when it occurs in the sutures; and this fracture is more difficult to discern when the bone is broken, on this account, that if there be a fracture, it is situated for the most part in the suture. For the bone is liable to be broken and slackened there, owing to the natural weakness of the bone there, and to its porosity, and from the suture being readily ruptured and slackened: but the other bones which surround the suture remain unbroken, because they are stronger than the suture. For the fracture which occurs at the suture is also a slackening of the suture, and it is not easy to detect whether the bone be broken and slackened by the indentation of a weapon occurring in the suture, or from a contusion of the bone at the sutures; but it is still more difficult to detect a fracture connected with contusion. For the sutures, having the appearance of fissures, elude the discernment and sight of the physician, as being rougher than the rest of the bone, unless the bone be strongly cut and slackened (for a cut and a hedra are the same thing). But it is necessary, if the wound has occurred at the sutures, and the weapon has impinged on the bone or the parts about it, to pay attention and find out what injury the bone has sustained. For a person wounded to the same, or a much smaller, extent, and by weapons of the same size and quality, and even much less, will sustain a much greater injury, provided he has received the blow at the sutures, than if it was elsewhere. And many of these require trepanning, but you must not apply the trepan to the sutures themselves, but on the adjoining bone.
