Starting from the staircase on the left, the reliefs show: Saint Gregory with the tiara, the pope's crown, Saint Augustine as scribe, twelve-year-old Jesus in the temple, Saint Jerome with the lion, followed by Ambrose with the beehive. The second, third and fourth reliefs are originals from the 15th century. Between the panels there are also wooden figures of the four evangelists: Luke, Matthew, John and Mark.
