The front of the choir is enshrouded by an Istrian stone ‘septo’, added in 1475 when Giacomo Morosini was Procurator of the church. In the stone panels are the busts in relief, emerging from foliage, of the Patriarchs and Prophets of the Old Testament. From the left and up above the observer can view: Abraham, David, St. John the Baptist, Enoch, Jonah, Jacob, Elisha, Daniel, Jeremiah, Zachariah, Moses, Elijah, Isaiah. The last one on the right, containing the inscription: «Soli Deo honor et gloria», portrays Morosini. On the side facing the bell tower: Samuel and Habakkuk; on the opposite side: Isaac and Ezekiel. Beneath the ambos are the four Doctors of the Church: St. Gregory the Great and St. Jerome on the left, while on the right, St. Ambrose and St. Augustine. Above the crowning, with an arch in the middle and two ambos on either side, there are the statues of eight apostles and St. Anthony and St. Francis attributed to Vittore Gambello known as Camelio (1460 circa – 1537). The Virgin and St. John, by the same sculptor, are positioned on top of the grand central arch and flank the stark Crucifix attributed to a Venetian carver. Underneath the two ambos, there are bas-reliefs portraying the four Doctors of the Church, which, together with the busts of St. Bernardino and St. Ludovico of Anjou (sculpted on the sides of the two gracious pillars which support the arch) are the work of Pietro Lom bardo. The rest is the work of his workshop.
