Dagon

Dagon (other-Hebrew. דָּגוֹן; from others-Hebrew. דָּגָן - grain, according to folk etymology from Hebrew. דג — fish).

A Western Semitic deity in the form of a half-human-half-fish.

Dagon primarily acted as the god of agriculture and fertility, invented the plow, taught people to sow grain and bake bread. In modern times, this interpretation has merged with the subculture of "Cthulhu Myths", where Dagon is a fantastic god of fish and the leader of amphibian humanoids.
