According to tradition, Saint Peter sent Apollinaris to Ravenna, Italy, as its first bishop. His preaching of the Good News was so successful that the pagans there beat him and drove him from the city. He returned, however, and was exiled a second time.
After preaching in the area surrounding Ravenna, he entered the city again. After being cruelly tortured, he was put on a ship heading to Greece. Pagans there caused him to be expelled to Italy, where he went to Ravenna for a fourth time.
He died from wounds received during a savage beating at Classis, a suburb of Ravenna. A beautiful basilica honoring him was built there in the sixth century.
