Avalon Camelot King Arthur: "Merlin," by Matt Hughes.

Myrrdin "Merlin", Celtic (Britania, Irish & Welsh) Sorcerer, Druid, Wizard and Magician. Originally an ancient Welsh Druid, priest of the old religion, and great magician. He was transformed in the later Arthurian sagas. Tradition says he learned his powerful magic from the Goddess in her forms of Morrigan, Viviane, Nimue, and Lady of the Lake. Legend says he now lies sleeping in a hidden crystal cave. Variants: Merddin, Merlyn. ~~~~~~~~~~~~~~ Art: "Myrddin" by Bob Nolin

Nimue is the Otherworld Goddess sometimes known as The Lady of The Lake. The Lady of The Lake appears throughout the Arthurian legends as a mysterious figure that offers advice and intervention. It is thought that a number of Goddesses have assumed this role including Morgan Le Fay and Vivienne, as well as Nimue.
