name of St Michael's Mount is Karrek Loos y'n Koos – literally "the grey rock in the wood", suggesting that the bay was once a forest. According to local tourism guides in the region, Lyonesse was once connected to the west of Cornwall and is firmly rooted in Cornwall's traditions and mythology. Cornish people around Penzance still get occasional glimpses at extreme low water of a sunken forest in Mount's Bay, where petrified tree stumps become visible adjacent to the Celtic Sea. John of Worcester, a famous English monk and chronicler, wrote in 1099 that St Michael's Mount (now an island in Mount's Bay) was five or six miles from the sea, enclosed in a thick wood. The importance of the maintenance of this memory can be seen in that it came to be associated with the legendary Brython hero Arthur, although the date of its inundation is actually c. 2500 BC.
