Amasio of Teano was a 4th-century Greek priest and the second bishop of Teano. After fleeing persecution from the Arian Emperor Constantius, he traveled to Italy following an invitation from Pope Julius I to preach in the Campania region. During his travels in Sora, he was known for performing miracles, such as curing a young boy suffering from gout. He was later appointed to the bishopric of Teano in 346 by the Pope, succeeding Saint Paris.
