Did You Know?

Old Testament references to a huge sea monster, Leviathan (in Hebrew, Liwyāthān), are thought to spring from an ancient myth in which the god Baal slays a multiheaded sea monster. Leviathan appears in the book of Psalms as a sea serpent that is killed by God and then given as food to creatures in the wilderness, and it is referred to in the book of Job as well. We began equating Leviathan with the political state after the philosopher Thomas Hobbes used the word in (and as the title of) his 1651 political treatise on government. Today, Leviathan often suggests a crushing political bureaucracy. Leviathan can also be immensely useful as a general term meaning "something monstrous or of enormous size."
