Beast, in the English language, is most often used as a synonym for animal. In South African English, often it refers more specifically to a cow or a large antelope, by analogy with the Dutch term beest (wildebeest, hartebeest).
The Beast is a figure who appears in Christian millennial end times prophecy from the Book of Revelation. Some believe he is synonymous with the Antichrist, while others say the Beast is the Antichrist's independent ally. The Beast is associated with the number 666, the Number of the Beast. The magician Aleister Crowley bestowed this title upon himself as a nickname.
Beast was one of the first successful alternate reality games, published by Microsoft.
