Atlantis would never have lost to Athens…and I say that as a Greek. Ancient Greek wasn’t there during the Atlantis era.
Now, speaking as a magus, according to Thoth, once Atlantis fell, people went to America, Egypt, Greece, Cyprus and other places and made civs there (ofc, the geography wasn’t the same as we have it today, so don’t try to find logic in that).
Also, it’s not a good idea to take Plato’s words literally, the same goes with Thoth’s words.
According to Plato, he got to know Atlantis from an Egyptian priest (if I remember correctly), so there was no record from it in Greece. Then again, Greeks didn’t like non Greek folks, so they kinda never had anything in their records about other civs (other than Egyptians I think, due to some events in history).
Anyways, that doesn’t really matter. Besides, the op wanted to know if Thoth could help him with his quest for knowledge.
@WHamilton3 So, my answer to your question is: absolutely! Ask him and find out what you need.
PS: @DarkestKnight I think the first city was Eridu (if I’m not mistaken), a sumerian city. I always wanted to visit its ruins. You know, to see how the first city was like XD.
