Saint James, the Apostle († 44 AD) was one of the Twelve Apostles of Jesus, and traditionally considered the first apostle to be martyred. He is also called James the Greater to distinguish him from James, son of Alphaeus and James the Just. James the Greater is the patron saint of Spain, and as such is often identified as Santiago.
