The second scene in the series depicts Pius VI celebrating mass in the Basilica of Santi Giovanni e Paolo, one of the largest churches in Venice and the pope’s residence during his stay. The mass included a performance of the Te Deum, a prayer of thanksgiving set to music by the Venetian composer Antonio Vivaldi (1678–1741). Traditionally, the Te Deum was recited in thanks to God for a special blessing, including a papal election or a royal coronation, and thus was appropriate for this historic papal visit.
