Tannin (Hebrew: תַּנִּין tannīn; Syriac: ܬܢܝܢܐ tannīnā plural: tannīnē; Arabic: التنين tinnīn, ultimately from Akkadian 𒆗𒉌𒈾 dannina) or Tunnanu (Ugaritic: 𐎚𐎐𐎐 tnn, likely vocalized tunnanu[1]) was a sea monster in Canaanite and Hebrew mythology used as a symbol of chaos and evil.[2]
Tannin appears in the Baal Cycle as one of the servants of Yam (lit. Sea) defeated by Baʿal (lit. Lord)[3] or bound by his sister, Anat.[4] He is usually depicted as serpentine, possibly with a double tail.[4]
The tanninim (תַּנִּינִים) also appear in the Hebrew Bible's Book of Genesis,[5] Exodus,[6] Deuteronomy,[7] Psalms,[9] Job,[10] Ezekiel,[11] Isaiah,[12] and Jeremiah.[13] They are explicitly listed among the creatures created by God on the fifth day of the Genesis creation narrative,[5] translated in the King James Version as "great whales".[14] The tannin is listed in the apocalypse of Isaiah as among the sea beasts to be slain by Yahweh "on that day",[15] translated in the King James Version as "the dragon".[16][n 1]
In Judaism, Tannin is sometimes conflated with the related sea monsters Leviathan and Rahab by Christians.[19][clarification needed] Along with Rahab, "Tannin" was a name applied to ancient Egypt after the Exodus to Canaan.[2]
The word Tannin is used in the Hebrew Bible fourteen times. Aaron's staff becomes Tannin in the Book of Exodus (Exodus 7:9-12), it is used in the meaning "snake" in the Book of Deuteronomy (Deut 32:33) and Psalms (Psalm 91:13). It represents Nebuchadnezzar II (the king of Babylon) in Jeremiah (Jeremiah 51:34) and Pharaoh in Ezekiel (Ezekiel 29:3, 32:2). In the Book of Job (Job 7:12) the protagonist questions God "Am I the sea or the sea dragon that you have set a guard over me?"[20]
The name has subsequently been given to three submarines in the Israeli Navy: the first, an S-class submarine formerly known as HMS Springer, was in commission from 1958 until 1972. The second, a Gal-class submarine, was in commission from 1977 until 2002. The third INS Tanin is a Dolphin-class submarine in commission since 2014.
In modern Hebrew usage, the word tanin (תנין) means crocodile.[21]
