The Pope then went to Civita Vecchia, in order to fortify it, and in his company were many lords; among others, Giovan Paolo Baglioni and Signor Vitello, and such persons of ability as Pietro Navarra and Antonio Marchissi, the architect for fortifications at that time, who had come from Naples at the command of the Pope. Discussions arising as to the fortification of that place, many and various were the opinions about this, one man making one design, and another a different one; but among so many, Antonio displayed before them a plan which was approved by the Pope and by those lords and architects as superior to all the others in strength and beauty and in the handsome and useful character of its arrangements; wherefore Antonio came into very great credit with the Court. After this, the genius of Antonio repaired a great mischief brought about in the following manner: Raffaello da Urbino, in executing the Papal Loggie and the apartments that are over the foundations, had left many empty spaces in the masonry in order to oblige some friends, to the serious damage of the whole building, by reason of the great weight that had to be supported above them; and the edifice was already beginning to show signs of falling, on account of the weight being too great for the walls. And it would certainly have fallen down but for the genius of Antonio, who filled up those little chambers with the aid of props and beams, and refounded the whole fabric, thus making it as firm and solid as it had ever been in the beginning.
