Oh gosh, a while ago I was arguing with a good friend of mine about a digital piece I made (placed it here also: [link]). A man with the head of a horse, we wondered what kind of mythical creature we could link him with. We were thinking of centaurs, but that's just the other way around off course. But I believe I finally figured it out now!
I am glad my work brought illumination to your debate. Although the Tikbalang is a mythical creature endemic to my people, I believe that there is a similar creature in ancient Greek myth and it is called a cellini (if my memory serves me right)
