The most prominent general, however, was C. Avidius Cassius, commander of III Gallica, one of the Syrian legions. Cassius was young senator of low birth from the north Syrian town of Cyrrhus. His father, Heliodorus, had not been a senator, but was nonetheless a man of some standing: he had been Hadrian's "ab epistulis", followed the emperor on his travels, and was prefect of Egypt at the end of Hadrian's reign. Cassius also, with no small sense of self-worth, claimed descent from the Seleucid kings. Cassius and Martius Verus, still probably in their mid-thirties, took the consulships for 166.
