Some of the pressure was subtle. On 15 March, Emperor Joseph II (1765–90) visited Rome to join his brother Leopold, the Grand Duke of Tuscany, who had arrived on 6 March. The next day, after touring St. Peter's Basilica, they took advantage of the conclave doors being opened to admit Cardinal Girolamo Spinola to enter as well. They were shown, upon the Emperor's request, the ballots, the chalice into which they would be placed, and where they would later be burned. That evening Gaetano Duca Cesarini hosted a party. It was the middle of Passion Week.
