I prefer not to describe St. Peter’s. It has been done before. The ashes of Peter, the disciple of the Saviour, repose in a crypt under the baldacchino. We stood reverently in that place; so did we also in the Mamertine Prison, where he was confined, where he converted the soldiers, and where tradition says he caused a spring of water to flow in order that he might baptize them. But when they showed us the print of Peter’s face in the hard stone of the prison wall and said he made that by falling up against it, we doubted. And when, also, the monk at the church of San Sebastian showed us a paving-stone with two great footprints in it and said that Peter’s feet made those, we lacked confidence again. Such things do not impress one. The monk said that angels came and liberated Peter from prison by night, and he started away from Rome by the Appian Way. The Saviour met him and told him to go back, which he did. Peter left those footprints in the stone upon which he stood at the time. It was not stated how it was ever discovered whose footprints they were, seeing the interview occurred secretly and at night. The print of the face in the prison was that of a man of common size; the footprints were those of a man ten or twelve feet high. The discrepancy confirmed our unbelief.
