For Eastern Christians, the Holy Feast of Baptism is more important than that of Nativity because it is the great Theophany, a manifestation of Christ's divinity. The iconography of the Baptism is simple and ancient, adhering closely to the Gospels. Christ is depicted at the moment of abasing himself by stepping into the river to be baptized when a voice from the heavens reveals him to be the Son of God. The rocky landscape of the Jordan Valley opens up into a whirlpool. John the Baptist leans over Christ, who dominates the waters and blesses him. With his baptism, Christ is renewed in his own person the primordial image of man had lost through sin.
