“The treatment experienced in this prison is certainly not so bad, in most cases, as it is in every other within the walls of Rome. The Castle of St. Angelo is chiefly set apart for prisoners of distinction. Cardinals and prelates who fall into disgrace with the Pope are confined in it. For this purpose there are a variety of apartments; in one of them are shown the iron rings that had the honour of securing the cord with which the celebrated Cardinals Caraffa, Coscia, and others, were hung. Pope Clement VII. was likewise a prisoner in this fortress, at the time of its occupation by the Imperial forces, which he himself had called into Rome. The records of this edifice, which, as everybody knows, was originally the mausoleum of the Emperor Adrian, would throw considerable light on the history of the papacy, and unfold many of the evil deeds of the popes. It has been the scene of the most unheard-of cruelties, as well as of the most shameless and revolting obscenities. The well-known orgies of Pope Alexander VI., which were celebrated partly in the gardens of the Vatican, and partly in the Castle of St. Angelo, have left a stain upon its walls which can never be effaced. Like the Pope’s bulls, it serves ‘_ad perpetuam rei memoriam_.’ In one of the halls are the notorious pictures by Julio Romano, of which it would be difficult to decide whether the artistical skill they display be more admirable, or the subjects they represent more grossly indecent and detestable. Colonel Calandrelli, one of the most valiant defenders of the republic, and a triumvirate after Mazzini--a gentleman equally learned in the history of his country, as he has shown himself brave in her service--has assured me that he has a work ready for publication, in which the whole history of this celebrated Castle is unfolded from authentic documents.”--Pp. 4, 25, 26, 465.
