Theophanes was one of the most intimate friends of Pompey, whom he accompanied in many of his campaigns, and who frequently followed his advice on public as well as private matters. Pompey held Theopanes in such high esteem that he presented him with Roman citizenship in the presence of his army, after a speech he eulogising his merits. Theopanes was appointed
praefectus fabrum, or chief-of-staff, to Pompey. Around 62 BC Theophanes took the name of Pompeius after his patron. Such was his influence with Pompey that, in the course of the same year, he obtained for his native city the privileges of a
free state, although it had espoused the cause of
Mithridates VI of Pontus, and had given up the Roman general,
Manlius Aquillius, to Pontus. Theophanes came to Rome with Pompey after the conclusion of the wars in the east. There he adopted
Lucius Cornelius Balbus, of Gades, a favourite of his patron. He continued to live in Pompey's household on close terms, and we see from
Cicero's letters that his society was courted by many of the Roman nobles, on account of his well-known influence with Pompey. When the civil war broke out he accompanied Pompey to Greece, where Pompey appointed him commander of the Fabri, and consulted him and
Lucceius on all important matters in the war, much to the indignation of the Roman nobles. After the
Battle of Pharsalus Theophanes fled with Pompey from Greece, and it was owing to his advice that Pompey went to Egypt, where he was killed. After the death of Pompey, Theophanes took refuge in Italy. He was pardoned by
Julius Caesar, and was still alive in 44 BC, as evidenced by one of Cicero's letters. == History of Pompey's campaigns ==
