Zeigeist movie claims the Egyptian Horus was crucified and resurrected. Turns out his eye was injured in fight with Seth (or Set), but he never died. He became Egypt’s king of the living, while his father Osiris (who did die, and was later revived by Isis) became king of the dead (or underworld).
Now two more promising candidates for a pre-Christian “crucifixion” and “resurrection” are named by Richard Carrier (the atheist/skeptic, historian grad student featured on “Internet Infidels”). I am working on an article now on those two, plus the response to “the devil imitated the prophecy” from St. Justin Martyr. Hope to finish in a few days.
To get to the punchline, Carrier claims the goddess Inanna (of the ancient Sumerians, or Ishtar of the Akkadians/Babylonians) was crucified and resurrected. Turns out Inanna was killed (in the underworld), and was then “hung on a nail [or stake]” or “hung from a hook on the wall.” She was then revived by sprinkling the “food of life” and “water of life” on the corpse, and “Inanna arose.” This all takes place in the “underworld.” Details in my article when done. The “Descent of Inanna” into the underworld is dated to about 1750 BC and is available online (here’s some commentary). Carrier claims this story was familiar to the ancient Israelites because “the weeping of Tammuz” (Inanna’s lover) is mentioned in Ezekiel 8:14.
Another one Carrier likes to mention is Zalmoxis (or Salmoxis, of the Thracians, about 5th century BC). Turns out Zalmoxis never died, but hid himself in an “underground chamber” for three years, then “appeared” to his followers. So there was no death and resurrection. The teaching of the Thracians (like the Greeks) was of the immortality of the soul, not bodily resurrection. Carrier claims the Thracians “believed in the physical resurrection of Zalmoxis” but I don’t see that in the story related by Herodotus (our main source for Zalmoxis). The entire (short) account is in my article.
