The Greek word aphros means “foam,” and Hesiod relates in his Theogony that Aphrodite was born from the white foam produced by the severed genitals of Uranus (Heaven), after his son Cronus threw them into the sea.
Semele was just a priestess who got diddled by Zeus, as you do, and got pregnant with Dionysus.
However, after shenanigans by Hera, she got tricked into asking Zeus to show himself to her in his full godly might, and because he was oathbound due to earlier power-of-boner stuff, he had to unwillingly comply.
He tried his best to show the tiniest sliver of his true being that would count, but she was still mortal, and got burned in godly flame for just witnessing him.
Zeus, saved the foetal Dionysus by strapping him to his thigh until the thigh-pregnancy was complete, and later, Dionysus found his mom in the underworld, and made her into the God of Drunk Frenzy.
Following all that, Semele appears to be uppity about her incredible husband to her sister, because Semeles husband carried their fetus to term after Semele died, while her sister's husband was a mere wife-and-son-murder-attempter.
I love out of context ancient greek mythology.
Btw, all that, makes Dionysus the only god in this graph, apart from Gaia herself, to not be the product of direct incest. (Is brain-parthenogenesis incest? Who knows)
Ouranos is the Greek spelling. As far as the Greek god is concerned, that is the better name.
Uranus is the Latin spelling. Just like the other planets planets are named Mercury not Hermes, Mars not Ares, Jupiter not Zeus, astronomers looked to Latin not Greek for naming.
However the person that named Uranus fucked up because while Uranus is the Latin spelling of Ouranos, the Romans called the God Caelus. Rather than use the Roman name (again, like Neptune instead of Poseidon), the person who named it just used the transliteration not the actual nomenclature.
Zeus had sex with someone then eats them while they're pregnant. He has a headache and they hit him with a hammer. Out pops Athena. I don't know about y'all but I wouldn't call that mysterious.
In the novel "Claudius The God" Caligula says that Claudius is his grand uncle, which is the same relationship that the dog Cerberus had to the god Apollo.
