The Baptism of Jesus
It represents the episode of the baptism of Jesus from the Gospel. John the Baptist sprinkles water on Jesus' head, while two angels on the banks of the Jordan river, are holding Christ's clothes and God from above states: "This is my beloved son: listen to him."
It was built between 1572 and 1578, and freely replicates Alessi's models, also for the interior setting.
The statues of Christ, the Baptist and the two angels, completed in 1578, are the work of an anonymous artist trained in Lombardy.
Initially, the project included a small stream of water, flowing inside the chapel, to simulate the Jordan River (the holes at the back are still visible).
The figure of the Eternal Father, in stucco, affixed to the vault, was shaped by Cristoforo Bossi from Milan, who also painted the frescoes and the statues (1584).
