The panel on the left shows an angel at the top; depicted in the centre is Saint James Major with a pilgrim’s hat and staff, and Saint Catherine with the attribute of her martyrdom, the broken wheel. Below are Saint Nicholas – holding a bishop’s crook, mitre and three gold balls – and John the Baptist. The panel on the right shows, next to an angel at the top centre, Pope Urban V with the heads of the apostles Peter and Paul he is said to have found in the Lateran Basilica. Next to him stands Saint Clare with the ciborium, and shown in the foreground are Saint Francis of Assisi and Saint Lawrence. The latter is holding the gridiron on which he was martyred. The two side panels together with the altarpiece formed a group in the Church of Santa Maria Forisportam in Lucca representing the death and assumption of Mary, for the upturned heads of the angel (on the right) and of James (on the left) refer directly to Mary’s assumption in the centre panel.
