In French romances, a knight who had grown up in the woods and spoke the language of animals.
He obtained the white foot of a stag by killing the lions which guarded it. By so doing he earned the hand of marriage of a lady who had come to Arthur's court and offered herself, together with her kingdom, to whomsoever could bring her the foot. But, as Tyolet was greatly fatigued, he gave the foot to another knight. The other knight, thinking Tyolet dead, pretended that he had accomplished the quest himself, but he was later exposed.
