When he entered the hall of the Perropont, he found that he and all his suite were surrounded by armed men, who led him into another apartment, called the Vicar's Hall, where he found the Abbate Alviano, the protonotary Orsino, Jacopo Santa Croce, and Rinaldo Orsino, who were all prisoners like himself; at the same time the governor received orders to seize the castle of Monte Giardino, which belonged to the Orsini, and take away all the jewels, all the hangings, all the furniture, and all the silver that he might find.
