In French romances, a knight whose forest upbringing mirrors that of Perceval. Raised by his widowed mother, he departed for Arthur’s court after seeing a knight.
His career was puncuated by the retrieval of a white stag’s foot for the daughter of the King of Logres, who had promised her hand to any knight that obtained it. He sustained heavy injuries during a fight with two lions that guarded the foot, but he managed to hand the object to another knight before collapsing. The other knight, assuming that Tyolet had died, represented himself as the victor, but was foiled when Gawain – who had discovered the injured Tyolet – exposed him. Tyolet was then able to marry the King of Logres’ daughter.
