It was then, in fulfilment of the vow he had made during his troubles, that Saint Damasus (for he became a saint long since, success being a great sanctifier) adorned the underground chapel of the apostles. The entrance to it is through the modern basilica of St. Sebastian. It is a low, semicircular chamber, with irregular walls, in which a row of arched graves (arcosolia) has been formed, which once were occupied, probably, by bodies of saints or martyrs. Near the middle of the chapel is the well, about seven feet square, within which are the two graves, lined with marble, where the bodies of the apostles are said to have lain hid. Fragments of painting still remain on the walls of this pit, and three faint and shadowy figures may be traced, which seem to represent the Saviour between St. Peter and St. Paul. Over the mouth of the well stands an ancient altar. However little credence may be given to the old legends concerning the place, it is impossible not to look with interest upon it. For fifteen hundred years worshippers have knelt there as upon ground made holy by the presence of the two apostles. The memory of their lives and of their teachings has, indeed, consecrated the place; and though superstition has often turned the light of that memory into darkness, yet here, too, has faith been strengthened, and courage become steadfast, and penitence been confirmed into holiness, by the remembrance of the zeal, the denial of Peter, and the forgiveness of his Master, by the remembrance of the conversion, the long service, the exhortations, and the death of Paul.
