Lantayn, Lantyan, Lencien
A city in Cornwall where King Mark often held court in Béroul’s Tristan. It was the home of the leper Ivain.
In the Fourth Continuation of Chrétien de Troyes’s Perceval, Mark holds a tournament in Lancien against the King with a Hundred Knights.
In this day, the name, Lantyan, belongs to a forest which is in the care of the Woodland Trust and a farm in Cornwall, near the River Fowey.
