Born into a senatorial family around 450, he held a significant political role as a secretary to the Burgundian kings. His religious influence was profound, as he successfully converted King Sigismund to Catholicism. Beyond his administrative duties, he was a prolific writer, leaving behind a substantial literary legacy that includes numerous letters and religious verse.
