Many miracles are related of St. Gregory, as that going to bless a church in honour of St. Agnes, which had been used by the Arians, he caused the relics to be placed on the altar, whereon a hog went grunting out of the church with a fearful noise; whence it was averred that the devil, who had been served in it by the heretic Arians, was driven out by the relics. Sometimes the lamps were miraculously lighted. One day a bright cloud descended on the altar, with a heavenly odour, so that from reverence no one dared to enter the church. At another time, when Gregory was transubstantiating the wafers a woman laughed; he asked her why she laughed? to which at length she answered, “because you call the bread which I made with my own hands the body of our Lord;” whereupon he prayed, and the consecrated bread appeared flesh to every one present; and the woman was converted, and the rest were confirmed. At another time, some ambassadors coming to Rome for relics, Gregory took a linen cloth which had been applied to the body of a saint, and enclosing it in a box gave it to them. While on their journey home they were curious to see the contents of the box: and finding nothing within it but the cloth, returned to St. Gregory complaining that he had deceived them. On this he took the cloth, laid it on the altar, prayed, pricked it with a knife, the cloth shed blood, and the astonished ambassadors reverently took back the box. Another time one who had been excommunicated by St. Gregory for having put away his lawful wife, bargained with certain sorcerers and witches for revenge; who, when the holy pope rode through the city, sent the devil into his horse, and made him caper, so that he could not be held; then with the sign of the cross the pope cast out the devil, and the witches by miracle becoming blind were converted, and St. Gregory baptized them; yet he would not restore their sight, lest they should read their magical books again, but maintained them out of the church rents. After his death there was a famine in Rome, and the people being falsely persuaded that St. Gregory had wasted the church property, gathered his writings to burn them; wherefore Peter, the deacon, who had been intimate with Gregory, affirmed, that “he had often seen the Holy Ghost, in form of a dove upon St. Gregory’s head whilst he was writing, and that it would be an insufferable affront to burn those books, which had been written by his inspiration;” and to assure them of this he offered to confirm it by oath, but stipulated that if he died immediately after he had taken the oath, they should believe that he had told them the truth: this being assented to, he took the oath, and thereupon died, and the people believed; and “hence the painters came to represent St. Gregory, with a dove at his ear, to signify that the Holy Ghost inspired and dictated what he writ.”[19]
