The Gospel of James is in three equal parts, of eight chapters each: -the first contains the story of the unique birth of Mary to Anna and her childhood and dedication to the temple, -the second starts when she is 12 years old, and through the direction of an angel, Saint Joseph is selected to become her husband. -the third relates the Nativity of Jesus, with the visit of midwives, hiding of Jesus from Herod the Great in a feeding trough and the parallel hiding in the hills of John the Baptist and his mother (Elizabeth) from Herod Antipas. One of the work's high points is the Lament of Anna. A primary theme is the work and grace of God in Mary's life, Mary's personal purity, and her perpetual virginity before, during and after the birth of Jesus, as confirmed by the midwife after she gave birth, and tested by "Salome" who is perhaps intended to be Salome, later the disciple of Jesus who is mentioned in the Gospel of Mark as being one of the women at the crucifixion. This is also the earliest text that explicitly claims that Joseph was a widower, with children, at the time that Mary is entrusted to his care. This feature is mentioned in the text of Origen, who adduces it to demonstrate that the 'brethren of the Lord' were sons of Joseph by a former wife.[6] Among further traditions not present in the four canonical gospels are the birth of Jesus in a cave, the martyrdom of John the Baptist's father Zechariah during the Massacre of the Innocents and Joseph's being elderly when Jesus was born. The Nativity reported as taking place in a cave remained in the popular imagination; many Early Renaissance Sienese and Florentine paintings of the Nativity continued to show such a setting, which is practically universal in Byzantine, Greek and Russian icons of the Nativity.
