first bishop of the Irish. According to Prosper of Aquitaine, as a deacon Palladius persuaded Celestine I (422–32) to send St Germanus, Bp. of Auxerre, to stamp out the Pelagian heresy in Britain, and was later himself sent to the Irish as their first bishop. Lives of St Patrick from the 7th cent. portray Palladius as an unsuccessful missionary who left the way open for Patrick; his career may perhaps have been subsumed within the legend of Patrick.
