"Once Percival and I were with Sir Bors, in the woods, and we saw a white deer being led by four lions. So we followed. We came to a hermitage, and all the animals went in to the chapel, where there was a holy man. He began singing mass. The animals were listening to it." He flutters his fingers against his thighs. "Then the deer turned into a man and sat upon the altar, and the lions changed also, into a man, and a lion, and an eagle and an ox."
