The four columns of the altar create a triptych with panels containing St. Benedict, the Virgin Mary, and St. Servulus. The three panels show an origin in Venice where the Benedictine Monastery of San Servolo was in the Venetian lagoon. It is attached to a 15th century blank leaf that was next to a gradual.
