Leviathan of the Book of Job is a reflection of the older Canaanite Lotan, a primeval monster defeated by the god Hadad. Parallels to the role of Mesopotamian Tiamat defeated by Marduk have long been drawn in comparative mythology, as have been wider comparisons to dragon and world serpent narratives such as Indra slaying Vrtra or Thor slaying Jörmungandr,[1] but Leviathan already figures in the Hebrew Bible as a metaphor for a powerful enemy, notably Babylon (Isaiah 27:1), and some scholars have pragmatically interpreted it as referring to large aquatic creatures, such as the crocodile.[2]
