“The Devil is usually black, symbolizing the absence of light and goodness. His skin is black, or he is a black animal, or his clothing is black. Sometimes he is a black rider on a black horse. His next most common hue is red, the color of blood and fire; he dresses in red or has a red or flaming beard; redheaded men and women are more subject to his influence than others. Occasionally he is green, owing to his association with the powers of vegetation, of forest wilderness, and of the hunt. . . .
The Devil comes from the north, domain of darkness and punishing cold. Curious connections exist between Satan and Santa Claus (Saint Nicholas). The Devil lives in the far north and drives reindeer; he wears a suit of red fur; he goes down chimneys in the guise of Black Jack or the Black Man covered in soot; as Black Peter he carries a large sack into which he pops sins or sinners (including naughty children); he carries a stick or cane to thrash the guilty (now he merely brings candy canes); he flies through the air with the help of strange animals; food and wine are left out for him as a bribe to secure his favors. The Devil’s nickname (!) “Old Nick” derives directly from Saint Nicholas.”
