OK, try Perseus next.
Perseus, son of Danae, prophesied to kill his grandfather. Hence gf immured Danae in bronze chamber with small hole for food and drink. Danae visited by Zeus in a shower of gold.
Now I don’t think that the Greeks thought that Zeus just sparkled on Danae for a couple seconds and wafted up through the hole again. Not in character. Zeus liked his ladies; he took bodily form and enjoyed her.
Not a virgin birth. Killing mother’s father, not a Christian element.
It's a bit difficult to take the "shower of gold" claim seriously as an original story since other children of Zeus were born through intercourse. Ancient Greek and Roman mythology has been changed in modern "retellings" to support the idea that virgin births and physical resurrections are present in religions other than Christianity. So. . .unless someone can show the original story had the "shower of gold" in it, and that the other stories of his intercourse to conceive children were false, I just don't buy it.
