Are we talking a sort of Gilgamesh thing where the kid has 1/3 mom’s genes, 1/3 one dad’s (Zeus) genes, and one third other dad’s (Hades) genes?
(Yes, it was a thing and they did believe that if a woman had sex with another man while pregnant, the baby would get an extra dad. It wasn’t seen as bad, heck getting extra from a strong second dad was seen as a good thing per Gilgamesh. It’s a case of technology and medicine has moved on from myth….)
Well… if we go by already existing Greek myth, we’d get someone like Dionysos.
Let me explain and bear with me because the timeline and rebirth part is going to be a doozy.
According to Orphic traditional myth, Persephone had a son named Zagreus.
The myths vary in whether Zeus (disguised as Hades because he’s a horny asshole, as per usual) is the father or if, due to a misunderstanding of the title, Hades was the father.
While it wouldn’t be out of character for Zeus to be that petty of an asshole and horny enough to rape his daughter, I’m more personally willing to bet Hades is the father for two reasons:
- Zagreus has many associations with Hades and the underworld beyond the fact that his mother is the Iron Queen of the Underworld herself. There’s even epic poems that refer to him as an underworld god of a high order, almost a possible successor to Hades, as “night-ranging Zagreus, performing his feasts of raw flesh.”
- When they speak of the union, Persephone’s partner is referred to as Chthonic-Zeus. Chthonic literally means "subterranean", but the word in English describes deities or spirits of the underworld, especially in Greek religion. So, basically, if Zeus controls the skies and Poseidon the seas, then Hades is the king of the earth and everything underneath it (hence why his Roman name is “the Rich One”). Since Zeus, being King of the Gods, is sometimes used poetically as a synonym for King, then it wouldn’t be out of place for “Chthonic-Zeus” to be a poetic way of referring to Hades, King of the Earth and all the treasures underneath it.
So, for the purpose of this exercise, let’s assume Hades is Zagreus’ father.
Zagreus was caught by Titans who dismembered him and boiled him in a cauldron in order to eat him. They ate everything except for his heart.
Apollo finds it and takes it to Mount Olympus.
Myths vary over who ground up Zagreus’ heart, put it in a potion, and slipped it to Semele’s drink (some say Apollo did, some say Athena did, some say Zeus did, some say Persephone had a hand in it…), but the end result is that Semele gets pregnant through that and now carries Zagreus’ soul in her fetus.
Of course, the problem is that Semele was also Zeus’ flavor of the week, and we all know how Hera reacts to that.
She promptly sent a lightning bolt Semele’s way to show her displeasure at Zeus screwing around and getting another mortal pregnant again.
Zeus managed to salvage the fetus but not the smear on the ground that used to be Semele. He then had the fetus sewed in to his thigh so he could carry it to term, then had a sort of c-section on his thigh when baby Dionysos was ready to be born.
(Yes, the thigh is a weird place, just go with it)
As a result, by being Zagreus reincarnation through the soul and through magic genetically preserving a part of his old body while adding Semele and Zeus’ genes, Dionysos is the manifestation of mixing Hades and Zeus’ genes and powers together (plus Persephone’s).
He’s the god of wine, ritual madness, rebirth, sex, the harvest, fertility, winemaking, theater, lack of inhibitions, and religious ecstasy.
That’s a pretty neat combo.
