Editing Lyonesse (section)

==Analogues in Celtic mythology==
The legend of a sunken kingdom appears in [[Cornish mythology|Cornish]], [[Breton mythology|Breton]] and [[Welsh mythology|Welsh]] mythologies. In Christian times, it came to be viewed as a sort of Cornish [[Sodom and Gomorrah]], an example of divine wrath provoked by unvirtuous living. A Breton parallel is found in the tale of the Cité d'[[Ys]] or Ker Ys, similarly drowned as a result of its debauchery, with a single virtuous survivor, King [[Gradlon]], escaping on a horse. According to Welsh legend, the kingdom of [[Cantre'r Gwaelod]] in [[Cardigan Bay]] was drowned due to the drunkard negligence of its prince, [[Seithenyn]], who allowed the sea to sweep through the floodgates.

The tale of Lyonesse is sometimes suggested to represent an extraordinary survival of folk memory of the flooding of the Isles of Scilly and [[Mount's Bay]] near Penzance<ref name=Hind>{{Cite book |last=Hind |first=C.

For example, the [[Cornish language|Cornish]] 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.
