'The Beast' is a figure in the Book of Revelation, the last book
of the New Testament. There are two beasts described in
Revelation 13; the First Beast arises out of the sea, having
seven heads and 10 horns. The Second (Lamb-like) Beast
arises out of the earth, having the appearance of a lamb
while speaking like a dragon. This Beast exercises authority
on behalf of the first beast, causing the Earth-dwellers
to make an image of the First Beast and worship him.
