When the triumvirate was formed in 43, Pollio was made Antony's legatus in Cisalpine Gaul and promised the consulship for the year 40.

During this year, in which Octavian had to besiege Lucius Antony at Perusia, Pollio, a legatus of Mark Antony, was naturally not on good terms with Octavian, and could hardly have used any influence in behalf of Vergil or any one else.

But he had been governor of Asia for three years (61-58 B.C.), and must have realised large sums even in that exhausted province; and at this moment he was legatus to Pompeius as special commissioner for organising the supply of corn, and thus was in immediate contact with one of the greatest millionaires of the day.
