Dagan, known in Hebrew as Dagon,[a] is a Semitic deity. When mentioned in the Bible, he is called a god of the Philistines, though no other evidence of this exists.[1] Dagan is the father of Hadad, who is better known by his title Baal.
Outdated scholarship portrayed Dagan as a fish god due to superficial resemblance of his name with the Hebrew word for "fish" (דָּג, romanized dāg).
Origin: Babylonia An ocean god worshipped by the Philistines. It's said his name comes from the Hebrew sounds for fish (dag) and idon (aon). There used to be important temples for Dagon in Gaza and Ashdod. Dagon is identified as the same as the Babylonian god Oannes. He is depicted with a male appearance, with a human's upper body and a fish's lower.
