Giorgio Vasari died before he was able to complete the massive arched fresco The Last Judgment. Vasari died in 1574, and the massive project took Federico Zuccaro 5 more years to complete. Designed to instill reverence and fear among the congregation below, the cupola is depicted as a temple that seats twenty-four elders of the Apocalypse. On the terraces below are choirs of angels, then groups of saints, then personifications of the gifts of the Holy Spirit, the virtues, and the beatitudes. The lowest tier, and most visible to visitors to the Duomo, is a gristly vision of hell replete with tortured sinners.
