Travellers pass this modest 9th-century Byzantine brick church without guessing that major dramas unfold inside. Under the carena di nave ceiling, Tintoretto’s Last Supper shows apostles alarmed by Jesus’ announcement that one of them will betray him. Giandomenico Tiepolo’s Stations of the Cross sacristy cycle shows onlookers tormenting Jesus, who leaps triumphantly from his tomb in the ceiling panel.
