'And upon that he placed the white staff in Angharad's hand, and instantly the goblin which she had hitherto seen as a handsome and honourable nobleman, appeared to her as a monster, inconceivably hideous; and she fainted from fear, and Einion supported her until she revived. And when she opened her eyes, she saw there neither the goblin, nor any of the guests, nor of the minstrels, nor anything whatever except Einion, and her son, and the harp, and the house in its domestic arrangement, and the dinner on the table, casting its savoury odour around. And they sat down to eat ... and exceeding great was their enjoyment. And they saw the illusion which the demoniacal goblin had cast over them.... And thus it ends.'[81] FOOTNOTE: [81] Iolo MSS. 587, et seq. V. There is hardly a goblin in the world more widely known than this spectre of the forest. Her story appears in the legends of very many lands, including China. Its ancient Grecian prototype is found in the Odyssey.[82] When it is the Diawl himself who appears in the role of the familiar spirit, his majesty is usually in some other form than that of a man, with hoofs, horns, and tail. The orthodox form of Satan has indeed been seen in many parts of Wales, but not when doing duty as a familiar spirit. A Welsh poet of the thirteenth century mentions this form: And the horned devil, With sharp hoofs On his heels.[83] He is variously called cythraul, dera, diafol, all euphemisms for devil, equivalent to our destroyer, evil one, adversary--as well as plain diawl, devil. In his character of a familiar spirit he assumes the shape of a fiery ball, a donkey, a black calf, a round bowl, a dog, a roaring flame, a bull, a goose, and numberless others, including the imp that goes into a book. In all this he bears out the character given him in old mythology, where he grows big or little at pleasure, and roars in a gale as Hermes, the wind-god, howls as a dog, enters a walnut as in the Norse Tale, or is confined in a bottle as the genie of the 'Arabian Nights.' To that eminent nonconformist preacher, Vavasor Powell, the devil once appeared in shape like a house. 'Satan ... appeared several times, and in several wayes, to me: as once like a house, stood directly in my way, with which sight I fell on my face as dead.... Another time, being alone in my chamber ... I perceived a strong cold wind to blow ... it made the hair of my flesh to stand up, and caused all my bones to shake; and on the suddain, I heard one walk about me, tramping upon the chamber floor, as if it had been some heavie big man ... but it proved in the end to be no other than ... Satan.'[84]
