Theophilus of Adana

Saint Theophilus the Penitent or Theophilus of Adana (died ca. 538) was a cleric in the sixth century Church who is said to have made a deal with the devil to gain an ecclesiastical position. His story is significant as it is the oldest story of a pact with the Devil and was an inspiration for the Faust legend. His feast day is February 4.

Eutychianus of Adana, who claimed to be an eyewitness of the events, is the first to record Theophilus's story. Although Theophilus is considered to be an historical personage, the tale associated with him is of an apocryphal nature.
