Another detail: it appears that another god was worshipped at Har Timna after Hathor. The pillars of the shrine were defaced and turned upside down when they were incorporated into the new shrine. A shrine to either Baal or Jehovah?
Check Zwickel, Wolfgang. 1999. "Der Solomanishe Tempel". Sorry, but that's all the info I have. There's a picture of the shrine and an archeological report. Also, check out http://www.bibleorig...Tabernacle.html.
Most of the archeological evidence for the Exodus is from Egyptian military/mining expeditions to Sinai. That's what I believe the Sinai part of the trip was. The Bible story is a reworked account of one of these (more than one?) expeditions.
If you're trying to disprove the biblical version of events, don't waste your breath. It wasn't literally true to begin with. And you'll never prove a negative, anyway. The biblical account is a legend that started with historical prototypes and grew from there, like our urban legends. But the prototypes existed and some of them can be demonstrated to have existed. Many of the place names and some the physical evidence is still there. The Temple to Hathor still stands at Gebel Ghorabi. The shrine to Hathor is still under a ledge at Har Timna. There is other evidence, too. Not that would prove the entire biblical account, but enough to show where the story came from. And it is those prototypes that I maintain are the true part of the story.
In land surveying there is a concept that the true property line is the one on the ground. The deed is only a description. That's what we have here. What happened, happened. The Bible is a description, not reality.
