Luke

Luke or Lucanus, author of the third Gospel, as well as the Acts, born in Antioch, a Greek by birth and a physician by profession, probably a convert, as he was a companion, of St. Paul; is said to have suffered martyrdom and been buried at Constantinople; is the patron saint of artists, and represented in Christian art with an ox lying near him, or in the act of painting; his Gospel appears to have been written before the year 63, and shows a Pauline interest in Christ, who is represented as the Saviour of Jew and Gentile alike; it was written for a Gentile Christian and in correspondence with eye-witnesses of Christ's life and death.
