A Christian priest, he was imprisoned for his beliefs at the time of the Emperors Diocletian and Maximian.
Gratefully, Pinianus liberated all of the Christian prisoners in his province and allowed Anthimus to hide himself in the governor's villa on the Via Salaria.
Now based in Italy, Anthimus converted many to the Christian faith and countless miracles were attributed to him.
His legend states that he was miraculously rescued by an angel, later recaptured, and then beheaded by order of the consul Priscus.
His body, during the time of Charlemagne, was transferred to Tuscany, near Montalcino, where St. Antimo's Abbey currently stands.
