As far as mere dimensions are concerned, the prison of Santa Giustina was not a hard one to swallow, being only three feet wide by about ten feet in length. In this limited space, Santa Giustina passed five years of the paternal reign of Nero (a virtuous and a long-suffering prince, whom, singularly enough, no historic artist has yet arisen to whitewash), and was then brought out into the larger cell adjoining, to suffer a blessed martyrdom. I am not sure now whether the sacristan said she was dashed to death on the stones, or cut to pieces with knives; but whatever the form of martyrdom, an iron ring in the ceiling was employed in it, as I know from seeing the ring,--a curiously well-preserved piece of ironmongery. Within the narrow prison of the saint, and just under the grating, through which the sacristan thrust his candle to illuminate it, was a mountain of candle-drippings,--a monument to the fact that faith still largely exists in this doubting world. My own credulity, not only with regard to this prison, but also touching the coffin of St. Luke, which I saw in the church, had so wrought upon the esteem of the sacristan, that he now took me to a well, into which, he said, had been cast the bones of three thousand Christian martyrs. He lowered a lantern into the well, and assured me that, if I looked through a certain screenwork there, I could see the bones. On experiment I could not see the bones, but this circumstance did not cause me to doubt their presence, particularly as I did see upon the screen a great number of coins offered for the repose of the martyrs' souls. I threw down some _soldi_, and thus enthralled the sacristan. If the signor cared to see prisons, he said, the driver must take him to those of Ecelino, at present the property of a private gentleman near by. As I had just bought a history of Ecelino, at a great bargain, from a second-hand bookstall, and had a lively interest in all the enormities of that nobleman, I sped the driver instantly to the villa of the Signor Pacchiarotti.
