, in this set of panels a painting of the prophet Ezekiel is rendered; the middle panel is a raised stucco relief and displays a scene from
life of Jesus, this panel illustrates the crowing of Jesus with thorns; and the bottom panel a statue of one of the twelve apostles, this being a
representation of St. James the Greater.
