The interior houses in the apse, the main altarpiece depicting a Byzantine (Cretan) icon of the Madonna of the Graces, given to Este by the Venice. A finely carved wooden choir stall is arrayed below in U-shape. The church also contains an altarpiece depicting the Martyrdom of St Sebastian (circa 1700) by Alberto Calvelli. Along the nave are niches with 15 stone sculptures of saints, prophets and allegories, sculpted by Pietro Zandomeneghi (1806–1866) and Valentino Panciera, called Besarel.[1] The statues are meant to have presaged or relate to the Life of Virgin: they include Amos, Daniel David, Debora, Anne, Elisabeth, John the Baptist, Simeon, Maria Soror Moysis, Castitas (chastity), Costantia (constance), Oratio (prayer), and Humilitas (humility).
The nave has eight slightly indented side altars and two chapels. The altarpieces of St Dominic and St Thomas Acquinas were painted by Antonio Zanchi. The altar of the Holiest Sacrament is made of polychrome marble. The center of the nave has a late-19th century fresco depicting the Coronation of the Virgin by Giovanni Battista Baldi. Baldi also painted the four evangelists in the spandrels of the dome, as well as the medallions along the nave depicting the doctors of the church (Leo the Great, Ambrosius, Augustine, and Jerome) and four allegories of virtues (justice, strength, temperance, and prudence). A canvas depicting the Consignment of the icon to the Dominicans (circa 1700) was painted by Nicola Grassi.[2]
