This character, possibly identical with Griflet, is the hero of a romance bearing his name which tells how Taulat came to Arthur’s court, killed a knight in front of the queen and said he would return each year to do the same. Jaufré was sent after him and, following various adventures, defeated him.
Jaufré married Lady Brunissen of the Castle Morbrun, whom Taulat had made to suffer. Another adventure took him through an enchanted fountain to the fairyland of Gibel, where he killed a monster called Felon of Albarua.
