 After the first few months of his incarceration he obtained spacious apartments, received the visits of friends, went abroad attended by responsible persons of his acquaintance, and was allowed to correspond freely with others.The letters written from St. Anna to the princes and cities of Italy, to warm well-wishers, and to men of the highest reputation in the world of art and learning, form the most valuable source of information, not only on his then condition, but also on his temperament at large.It is singular that he spoke always respectfully, even affectionately, of the Duke.
