Lotan
Lotan (Ugaritic: 𐎍𐎚𐎐"-ltn", transliterated "Lôtān", "Litan", or "Litānu", meaning "coiled") is a servant of the sea god Yam defeated by the storm god Hadad-Baʿal in the Ugaritic "Baal Cycle". possibly with the help or by the hand of his sister ʿAnat. Lotan seems to have been prefigured by the serpent "Têmtum" represented in Syrian seals of the 18th–16th century BC, and finds a later reflex in the sea monster "Leviathan", whose defeat at the hands of Yahweh is alluded to in the biblical Book of Job and in Isaiah 27:1. Lambert (2003) went as far as the claim  that Isaiah 27:1 is a direct quote lifted from the Ugaritic text, correctly rendering Ugaritic "bṯn" "snake" as Hebrew "nḥš" "snake". "Lotan" ("ltn") is an adjectival formation meaning "coiled", here used as a proper name; the same creature has a number of possible epitheta, including "the fugitive serpent" ("bṯn brḥ") and maybe (with some uncertainty deriving from manuscript lacunae) "the wriggling serpent" ("bṯn ʿqltn") and "the mighty one with seven heads" ("šlyṭ d.šbʿt rašm"). The myth of Hadad defeating Lotan, Yahweh defeating Leviathan, Marduk defeating Tiamat (etc.) in the mythologies of the Ancient Near East are classical examples of the  Chaoskampf mytheme, also reflected in Zeus' slaying of Typhon in Greek mythology and Thor's struggle against Jörmungandr in the Gylfaginning portion of the Prose Edda. The Litani River that winds through the Beqaa Valley in Lebanon is named after Lotan as the river was believed to be the personification of the god.
