The <em>Baptism of Christ</em> was commissioned presumably some time about 1440 by the Camaldolese Monastery of Sansepolcro in Tuscany, originally part of a triptych. Its dating to Piero della Francesca's early career is evidenced by the strong relationship with the "light painting" of his master, Domenico Veneziano. It portrays Christ being baptised by John, his head surmounted by a dove representing the Holy Spirit. Christ, John's hand, the bird and the bowl form an axis which divides the painting in two symmetrical parts. A second division is created by the tree on the left, which instead divides it according to the golden ratio.
