The raven often appears in mythology. It is a symbol in many different cultures, perceived as a wise all-knowing bird, a bird of death and destruction, a bird of battle. The raven was the emblem of William the Conqueror and of the Norsemen, who once ravaged England. It is believed by many that King Arthur still lives in raven form. It is a symbol of the English Crown: if the ravens leave the Tower of London, so legend says, the Crown will fall, and England, too. The raven's colours are appropriate: once white, it was turned black by the god Apollo, who was angered by bad news it carried. And, despite its omen as a bird of destruction, the raven can bring good fortune, too. (History of Football at Carleton, T.J. Scanlon, 1966).
