On the way, he was intrusted with an important mission to Sicily.

He appears to have returned to Byzantium with Belisarius in 535.

He is heard of again, in 536, as charged with another mission in the neighbourhood of Rome, which shows that, at the end of 535, he had accompanied Belisarius, who had been despatched to Italy and Sicily to conquer the territory in the occupation of the Goths.

This expedition terminated successfully by the surrender of Vitiges and his captivity at Byzantium in 540.
As the reward of his services, Justinian bestowed upon him the title of "Illustrious" (_Illustris_), given to the highest class of public officials, raised him to the rank of a Senator, and, finally, appointed him Praefect of Byzantium in 562.

He does not, however, seem to have been altogether satisfied: he complains of having been ill-paid for his labours; for several years he was even without employment.
