The fresco depicting the voyage of
Moses is the first on the wall right to the altar, and faces the
Baptism of Christ on the opposite wall. The painting shows Moses (dressing in yellow and green as in the other frescoes of the cycle) leaving for Egypt, after he had been exiled from
Midian, with
Zipporah to his right. In the center, an angel asks him to circumcise his son
Eliezer (scene on the right), as a sign of the alliance between
Yahweh and the
Israelites. The baptism, depicted on the opposite fresco, was in fact considered by several early Christian writers, including
Augustine, as a kind of "spiritual circumcision". The ceremony is on the right, and includes Zipporah. In the right background
Moses and Zipporah are greeting
Jethro before leaving. Natural elements include the hill landscape in the background, characterized by thin trees (including a palm, a symbol of Christian sacrifice), and the birds: two of them are mating, an allusion to the renovations cycles of the nature. On the left background is a group of shepherds. The dames with flying dresses were a common element of Florentine early Renaissance painting, used also by
Ghirlandaio and
Botticelli. ==References==
