At about the same time he took to wife Calpurnia, daughter of Lucius Piso, who was to succeed him in the consulship, and affianced his own daughter Julia to Gnaeus Pompeius, breaking a previous engagement with Servilius Caepio, although the latter had shortly before rendered him conspicuous service in his contest with Bibulus. And after this new alliance he began to call upon Pompey first to give his opinion in the senate, although it had been his habit to begin with Crassus, and it was the rule for the consul in calling for opinions to continue throughout the year the order which he had established on the Kalends of January.
Sub idem tempus Calpurniam L. Pisonis filiam successuri sibi in consulatu duxit uxorem suamque, Iuliam, Gnaeo Pompeio conlocavit repudiato priore sponso Servilio Caepione, cuius vel praecipua opera paulo ante Bibulum inpugnaverat. Ac post novam adfinitatem Pompeium primum rogare sententiam coepit, cum Crassum soleret essetque consuetudo, ut quem ordinem interrogandi sententias consul Kal. Ianuariis instituisset, eum toto anno conservaret.
