James, the Lesser or Younger, son of Alpheus, or Cleophas and Mary, lived in Galilee. He was the brother of the Apostle Jude.
According to tradition he wrote the Epistle of James, preached in Palestine and Egypt and was crucified in Egypt. James was one of the little-known disciples. Some scholars believe he was the brother of Matthew, the tax collector. James was a man of strong character and one of the most fiery type. Tradition tells us that he also died as a martyr and his body was sawed in pieces. The saw became his apostolic symbol.
