Simon the Zealot was one of the most obscure among the apostles of Jesus. A few pseudepigraphical writings were connected to him, and his name occurs in all of the Synoptic Gospels and the Book of Acts each time there is a list of apostles, without further details. His feast is celebrated on May 10 (Eastern Christianity) and October 28 (Western Christianity) and he is a Holy Patron of curriers; sawyers; and tanners.
