Wow, you're definitely skipping some big ones there.
No, just pointing out that what is lacking is a dying and rising
motif that is being recycled, rather than a force-fitting of myth into a preconceived pattern inspired by Christianity.
Let's see--Osiris died, was resurrected. Had women attending his death and crying over him and everything.
In one legend of the conception of Horus, Osiris is briefly resurrected long enough to have sex with Isis, and then goes back to being dead and becomes lord of the underworld.
Dionysus died, was resurrected. Also attended by women. (And was a virgin birth, too!)
Dionysus was killed by the Titans as a baby by being stabbed to death, and then he was cooked and eaten. He never dies as an adult. His mother was Zeus' lover, so saying it was a virgin birth was a stretch. He did go to the underworld to rescue his dead mother, but he entered the underworld by way of the lake of Lerna, rather than by being killed, so he was as alive as Hades or Persephone in the underworld.
Persian Mithras was not only super popular in Rome at the time, he was buried in a tomb and rose from there.
This is actually simply wrong. Mithras never died.
(By the way, it is probably a mistake to assume continuity between the Persian Mithra and the Roman Mithras. Franz Cumont, who, IIRC, was a groundbreaker in Mithraic studies, had understandably thought that there was continuity, but later scholars found that it didn't pan out. See Manfred Clauss' book
The Roman Cult of Mithras.)
Tammuz, Akkadian, and Damuzi, Sumerian, were two versions of a vegetation deity who dies during summer, and is rescued from the underworld by Ishtar, who brings him back to life.
Tammuz, though, still gets stuck in the underworld for half a year, and for the other half, he is replaced by Ishtar's (or Inanna's) sister, Geshtinanna. This is actually reminiscent of a real motif in pagan myth, bilocation, the most famous example of which is the story of Hades, Demeter, and Persephone.
Atys, Phrygian deity, (a religion well-known in Rome at the time, as Atys's lover, Cybele, was biiig in Rome) had a lot of the resurrection motifs going on, being a deity associated with grain, harvest, sowing, etc.
The evidence for this is actually pretty thin. Some of it comes from a questionable interpretation of the five-day festival of Cybele. Scholars thought that if there was mourning for Attis on the festival's Day of Blood, then the celebration on the subsequent day, the Day of Joy, must have been for Attis' resurrection. The connection of the Day of Joy, according to J. Z. Smith, is based on "a fifth-century biography of Isidore the Dialectician by the Neoplatonic philosopher Damascius, who reports that Isidore once had a dream in which he was Attis and the Day of Joy was celebrated in his honor!" ("Dying and Rising Gods,"
Encyclopedia of Religion) Smith also notes a reference to the work
De errore profanarum religionum, which dates from about the fourth century, by Firmicus Maternus (verse 22.3), but according to him the passage does not name Attis and is probably about a late Osirian ritual. BTW, I have not been able to track down copies of these works of Damascius and Firmicus Maternus.
We can argue all you want about how much influence any of the local myths might have had on the myths of Jesus, but there were definitely a LOT of them in the area at the time, many of them well entrenched and establish long before Christianity.
There are far fewer than are claimed, and of the real ones left, there aren't much in the way of commonalities except for the bare points of dying and rising, which is what you'd expect if one was not dealing with a true motif, but a pattern imposed on the text.
And as a professor I had, in a class on the conflict between Romans and Christians, pointed out--in the climate at the time, this sort of myth was commonplace.
That's not too surprising, since the "dying and rising god" category has been taken seriously for quite a while, even when it hasn't been used in anti-apologetics. It is starting, though, to
show its problems.
