[1] According to Priscus, he was sent by Eastern Roman Emperor Theodosius II as an envoy to the King of the Huns, Attila in 442/443.
In 449, Attila stated that he would accept as envoy only Senator, Anatolius and Nomus, all of consular rank.
He was a recipient of Theodoret's letter requesting tax reduction on his city in 445–447.
[3] In 451, he was present during some sessions of the Council of Chalcedon, which is his last action to be reliably recorded in the sources.
