Leviathan, name comes from Hebrew meaning “coiled” or “twisted on.” In Deuteronomy he is listed as one of the seven princes of Hell. Psalm 104 implies that God made Leviathan to “sport with.” The Book of Job, Chapter 41, describes this great beast as a sea creature which Jewish lore incorporated into a sea monster, a horrid being capable of swallowing a whale a day.
Some say that Jonah narrowly escaped from being eaten by a Leviathan because the whale that he was in avoided the sea monster.
In a legend told by Rashi, a rabbi in eleventh-century France, tells that God created both a male and female Leviathan but killed the female shortly thereafter, because if the two were to procreate, mankind could not stand against them.
Another story in the Talmud says on the Day of Judgment God will sly the Leviathan, using its meat to prepare the great feast for the righteous and using its hide for the tent in which the feast was held.
Leviathan is mentioned in the Sixth and Seventh Books of Moses associated with a spell. Most probably this demon’s influence stems from the Babylonian-Sumerian adoration of Tiamat, monster, which crept into Jewish myth.
Sea serpents were prominent in Ancient Near East mythology extending back to the third millennium BCE. This includes the myths of the god Ninurta defeating the seven-headed-serpent, Baal vs. Yam (Canaanite), Marduk vs. Tiamat (Babylonian), Alum vs. Nehebkau (Egyptian).
In the Ugarit records the helpers of Yam are described as the “wiggling serpent” and the “mighty one with seven heads.” It is in Isaiah 27:1 that the term Leviathan is used not being distinct as to describing a creature or political leader. In Psalm 104 Leviathan is just described as a creature of God, not harmful.
Is it possible the author of Job took Leviathan malice characteristics from the Egyptians, where the serpent is the enemy of the sun-god?
Leviathan supposedly is involved in the trial of the Jesuit priest Urbain Grandier in the seventh century. Grandier was tried and burned at the stake for having sexually possessed the nuns in a convent in Loudon, France. The priest allegedly signed a pact with Satan on which Leviathan appears as a witness.
Leviathan in Satanism as described in The Satanic Bible by Anton Szandor LaVey represents the element of Water and the direction of West. Water symbolizes life and creation. It is believed that Leviathan is one of the seven princes of Hell, taken from the Sacred Magic of Abramelin the Mage.
