Bab-el-Mandeb, which means gate of tears, is the name given to the strait at the southern end of the Red Sea and identified by some researchers as the location of the Pillars of Heracles referred to by Plato. This idea is advocated by Jacques Hébert, Thérêse Ghembaza and Sunil Prasannan who have respectively located Atlantis at Socotra, Meroë and Sundaland.
A fictional account of the destruction of Atlantis in the Red Sea and its relationship with the biblical Deluge by Orson Scott Card is now available on the Internet(a).

Thérêse Ghembaza is a French researcher who has a website, in French and English, entitled The Great Enigmas of Antiquity(a) in which she discusses matters such as the Hyksos, the identity of Moses and the Kushites. The site also deals with her theory that Atlantis had been situated in Meroë on the Upper Nile, a theory that she developed in another paper(c), which is certainly worth a read.
While at first sight this might be seen as a wild claim, Ghembaza offers a well reasoned theory which was presented to the 2nd Atlantis Conference held in Athens in 2008. She has imaginatively linked aspects of Meroitic geography and history with Plato’s story of Atlantis. For example, she identifies Tyrrhenia with Tyre in Lebanon and claims that Tyrrhenia in Italy was a later colony of Tyre! While some of her ideas are convincing I found others a little threadbare. Nevertheless Ghembaza must be applauded for her efforts to construct a scientific explanation for the Atlantis narrative.
Ghembaza has kindly drawn my attention to two quotations from Pliny the Elder and Ovid that offer possible explanations for Plato’s orichalcum (see Document 091011). The former refers to a Cypriot copper mixed with gold which gave a fiery colour and called pyropus, while Ovid also refers to a cladding of pyropus, a term often translated as bronze. She also mentions auricupride(Cu3Au), an alloy that may be connected with orichalcum.

Panchaea was an island in the Indian Ocean first mentioned by the Greek philosopher Euhemerus in the 4th century BC. It is conventionally assumed to be fictional(b) as it shares many of the characteristics of Plato’s Atlantis.
Nevertheless, Thérêse Ghembaza has boldly proposed(a) that Meroë on the Upper Nile, which can be loosely described as an island, was in fact the Panchaea described by Diodorus Siculus and was, by extension, Plato’s Atlantis.
