The Magic of Crystals-Merlinite
Merlin (from wikipedia) is a legendary figure best known as the wizard featured in Arthurian legend. The standard depiction of the character first appears in Geoffrey of Monmouth‘s Historia Regum Britanniae, written c. 1136, and is based on an amalgamation of previous historical and legendary figures. Geoffrey’s rendering of the character was immediately popular, especially in Wales.
Later writers expanded the account to produce a fuller image of the wizard. Merlin’s traditional biography casts him as a cambion: born of a mortal woman, sired by an incubus, the non-human from whom he inherits his supernatural powers and abilities. The name of Merlin’s mother is not usually stated but is given as Adhan in the oldest version of the Prose Brut. Merlin matures to an ascendant sagehood and engineers the birth of Arthur through magic and intrigue. Later authors have Merlin serve as the king’s advisor until he is bewitched and imprisoned by the Lady of the Lake.
Nikolai Tolstoy hypothesizes that Merlin is based on a historical personage, probably a 6th-century Druid living in southern Scotland. His argument is based on the fact that early references to Merlin describe him as possessing characteristics which modern scholarship (but not that of the time the sources were written) would recognize as Druidical – the inference being that those characteristics were not invented by the early chroniclers, but belonged to a real person. If so, the hypothetical Merlin would have lived about a century after the hypothetical historical Arthur.
