Mythical Lady of the Lake 16 x 20 inch oil on canvas. The Lady of the Lake: bestower of Sovereignty, weaver of magicks, maker of the magical sword Excalibur, healer of the wounded King -- what dark visions of an elder and enchanted time her legend brings to mind! And yet, if we go back to the original Arthurian material, composed in Wales during the 12th century and earlier, we do not find her. Nor was she a product of the later French Arthurian romances. The Lady of the Lake is older still, older than Celtic Christianity; she is the Irish Goddess/Saint Brigid, the Welsh enchantress Ceridwen, and many other Ladies of the Depths -- the primal Dark Mother Goddess, patroness of Celtic Shamanism.
