The Wikipedia page on Achilles is interesting. He is featured in the Iliad, but the part about him being invulnerable except for his heel was added centuries later, and directly contradicts parts of the Iliad. Also, there’s an alternate version where his mother tried to make him immortal by covering him in ambrosia and burning him.
I guess the ancient Greeks were less strict about the particulars of their religion than anyone in the present day.
