Simon the Zealot (Saint Simon in Catholic and Orthodox traditions} was one of Jesus's twelve Apostles. He was nicknamed "the Zealot" because of his membership in the Zealite party, which was a violent faction at the time.  The Zealots were a nationalistic sect with very strong political views. St. Simon is also known for his rigid adherence to the Jewish law and to the Canaanite law. He was one of the original followers of Christ.
Saint Simon's usual attribute is the saw, since his body was said to have been sawed to pieces, and more rarely the lance.
