圖魯夫圖魯維斯的傳說最早是紀錄在 De Mirabilibus Britanniae 的子章節——《Wonders of Britain》之中。下為摘錄段落（這邊採用的名稱是 Troynt）
There is another wonder in the region called Buelt. There is a heap of stones, and one stone laid on the heap having upon it the footmark of a dog. When he hunted the swine Troynt(→Troit), Cabal, which was a dog of the warrior Arthur, impressed the stone with the print of his foot, and Arthur afterwards collected a heap of stones beneath the stone in which was the print of his dog's foot, and it is called Carn Cabal. And people come and take away the stone in their hands for the space of a day and a night, and on the next day it is found on its heap.
