## Life

The first pope to travel to Constantinople, sent under duress by the Arian king Theodoric to plead for Arians in the East — received with immense honor, he crowned the emperor at Easter. Theodoric, suspicious of that very honor, imprisoned him at Ravenna on his return, where he died of hardship.
