Rastrelli tells us that “on the 5th January, 1536, in carnival time, the Duke and Lorenzino disguised themselves as mountaineers and on sorry donkeys rode about the town paying visits to their mistresses and playing practical jokes. Thus passed the day, and towards evening they returned weary to the palace and supped together. Then Lorenzino said to his cousin, What shall we do to-night? and the Duke replied, I shall go to bed for I am tired out. Whereupon the traitorous Lorenzino whispered something in the Duke’s ear, who sprang up, went to his room and took a mantle lined with rich fur. Girding on his sword and putting his dagger in his belt, he left the palace secretly by the garden wicket, followed by Giomo da Carpi, Unghero, Captain Giustiniani of Cesena and one of his own body servants. On the Piazza S. Marco he met Lorenzino who was awaiting him and dismissed his attendants, and the two cousins returned to Lorenzino’s house. The Duke began to loosen his belt, but Lorenzino undid it entirely and took from him his sword and dagger, entangling the belt so dexterously round the handles of both that they could not be easily drawn. After a while the Duke asked at what hour the expected lady would arrive, and Lorenzino answered: She waits for me to fetch her. Go then, said Alessandro, and in order that she may not be recognized give her my mantle, and as he spoke he began to take it off. But Lorenzino, who wished him to be wrapped round as far as possible and impeded in his movements, answered: No, she will know how to disguise herself properly; and without further ado left the room, taking care so to close the door that it could only be opened from the outside. The Duke, being very tired, threw himself on the bed in his mantle and fell asleep.
