Ancient Mythology and the Hippocamps

Hippocamps are obviously the most prevalent sea bulls, sea panthers and sea lions. We presume hippocamps were first and then it seems to be later innovations where artists just literally must have said you know if we have a half fish half horse thing why can't we do that with other terrestrial animals? So all i know that lines up exactly and so this is again why you study greek mythology you know. Well my other favorite is the like seagot Capricorn which is also baffling in weird in a great way but there's only a handful of even visual representations from ancient mythologies.
