The lower one represents perhaps St. John preaching from a pulpit and his imprisonment on the right side.
In the central, the Feast of Herod and Salome to whom is presented the head of St. John.
Finally in the top, scenes of the Nativity of Christ: Annunciation to Mary, visiting her cousin Isabel, Adoration of the Magi, Birth and Circumcision.
