"In this time it happed that there was at Rome a dragon in a pit, which every day slew with his breath more than three hundred men. Then came the bishops of the idols unto the emperor and said unto him: O thou most holy emperor, sith the time that thou hast received Christian faith the dragon which is in yonder fosse or pit slayeth every day with his breath more than three hundred men. Then sent the emperor for S. Silvester and asked counsel of him of this matter. S. Silvester answered that by the might of God he promised to make him cease of his hurt and blessure of this people. Then S. Silvester put himself to prayer, and S. Peter appeared to him and said: "Go surely to the dragon and the two priests that be with thee take in thy company, and when thou shalt come to him thou shalt say to him in this manner: Our Lord Jesus Christ which was born of the Virgin Mary, crucified, buried and arose, and now sitteth on the right side of the Father, this is he that shall come to deem and judge the living and the dead, I commend thee Sathanas that thou abide him in this place till he come. Then thou shalt bind his mouth with a thread, and seal it with thy seal , wherein is the imprint of the cross. Then thou and the two priests shall come to me whole and safe, and such bread as I shall make ready for you ye shall eat."
