Calvisius was praetor possibly in 46 , but more likely in 44 BC . In 45 , he was governor of '' Africa Vetus '' , the province formed from Carthaginian territory after the Third Punic War , while C. Sallustius Crispus , the historian usually known as Sallust , became the first governor of '' Africa Nova '' , the province created by Caesar from the former kingdom of Numidia . The previous year , the senatorial forces had rallied in Africa after their defeat at Pharsalia , and the Battle of Thapsus meant that the outcome of the war had been determined on African soil . Calvisius had returned to Rome sometime before 15 March 44 , when he was present in the senate during Caesar 's assassination , but he had left two legates at Utica who may have caused trouble for his successor , Quintus Cornificius
