On the Seventh Day of Christmas: Pope St. Sylvester sewed the mouth of a dragon shut.

Sylvester, Pompous Maximus

Yes he dee-id.

Thus as S. Peter had said, S. Silvester did. And when he came to the pit, he descended down one hundred and fifty steps, bearing with him two lanterns, and found the dragon, and said the words that S. Peter had said to him, and bound his mouth with the thread, and sealed it, and after returned, and as he came upward again he met with two enchanters which followed him for to see if he descended, which were almost dead of the stench of the dragon, whom he brought with him whole and sound, which anon were baptized, with a great multitude of people with them.
