Mare owned by King Arthur in Welsh folklore
From Wikipedia, the free encyclopedia
Llamrei was a mare owned by King Arthur, according to the Welsh tale "Culhwch and Olwen" this horse was used to hunt and kill a boar.[1]

Close to Llyn Barfog in Wales is a hoof-print etched deep into the rock "Carn March Arthur", or the "Stone of Arthur's Horse", which was supposedly made by King Arthur's mount, Llamrei, either when the horse jumped from a clif to avoid invading saxons[2]or when the horse was hauling the terrible Addanc, or "afanc" monster, from the lake.[3]
