The Catholic Church commemorated Cornelius by venerating him, with his Saint's Day on 16 September, which he shares with his friend Cyprian. His Saint's Day was originally on 14 September, the date on which both Cyprian and Cornelius were martyred, according to Jerome. Cornelius's saintly name means "battle horn", and he is represented in icons by a pope either holding some form of cow's horn or with a cow nearby. He is the patron against earache, epilepsy, fever, twitching, and also of cattle, domestic animals, earache sufferers, epileptics, and the town of Kornelimünster, Germany, where his head is enshrined.
