God of the sea, earthquakes and horses.
In some versions of the myth, he just… he really liked horses. Don’t ask me why, I don’t even know. This guy had the hots for Demeter who was like ‘ugh whatever make me the most beautiful creature and I’ll consider it’. So he set to work making all sorts of horse-variants (like centaurs and mer-centaurs etc) until he fell upon our traditional horse only to find that in creating the most beautiful creature he was no longer interested in Demeter. Not sure what to make of that ending but have fun with it.
