Chapter CV Of the Altar and the Four Chalices Discovered Under the Earth
In that place where the prayers of Saint Patrick had dispersed the darkness which had been raised by the magicians, a church was builded, wherein he promoted one of his disciples, named Ailvius, unto the priesthood, that he there might minister. And he complained unto the saint that the matters needful for his ministry were wanting unto him. Then the saint, instructed of heaven, showed him under ground an altar of wonderful workmanship, having at its four corners four chalices of glass, and enjoined him to dig them forth carefully, lest perchance they should be broken; and the priest did accordingly, and found all things as the saint had foretold. But by whom this altar was made, or with the chalices there deposited, to me is yet unknown. Some, however, think that they were placed there by Palladius or his associates, being placed there after his departure.
