The Sahara Desert and in particular its northern regionshas attracted its share of attention from Atlantis investigators. However unlikely it may appear as a possible location for Atlantis it must be kept in mind that the Sahara of prehistory was very different from what we see today. Not only was it wetter at various periods in the past, but also there is clear evidence for the existence of a large inland sea extending across the borders of modern Algeria and Tunisia. This evidence is in the form of the chottsor salt flats in both countries. This proposed sea is considered by some to have been the Lake Tritonis referred to by classical writers. It is suggested that some form of tectonic/seismic activity, common in the region, was responsible for isolating this body of seawater from the Mediterranean and eventually turning it into the salt flats we see today.
An even more extensive inland sea, further south, was proposed by Ali Bey el Abbassi and based on his theory a map was published in 1802 which can be viewed online(c).
A 2013 report in New Scientist magazine(d) revealed that 100,000 years ago the Sahara had been home to three large rivers that flowed northward, which probably provided migration routes for our ancestors.
A September 2008 article in National Geographic pointed out that the Saharan climate has been similar for the past 70,000 years except for a period beginning 12,000 years ago when a number of factors combined to alter this fact. A northerly shift by seasonal monsoons brought additional rain to an area the size of contiguous USA. This period of a greener Sahara lasted until around 4,500 years ago. An interesting question might be; what happened circa 2500 BC to cause this reversal?
In 1868, it was proposed by D.A. Godron, the French botanist, that the Sahara was the location of Atlantis. In 2003, the non-existent archaeologist Dr.Carla Sage announced that she was hoping to lead an international expedition to the Sahara in search of Atlantis. Her contention was that “Atlantis was the capital of a vast North Africanempire with ports on the Gulf of Sidra”. *[This report is now confirmed to have been a hoax! I am indebted to Stel Pavlou for uncovering the origin of this story(e).]*
David Mattingly, an archaeologist at Leicester University has found that an ancient people known as the Garamantes had an extensive civilisation in the Sahara. He has evidence of at least three cities and twenty other settlements. The Garamantes reached their peak around 100 BC and then gradually diminished in influence as fossil water supplies reduced until in the 7th century AD they were subjected to Islamic domination. Some researchers have identified the Garamantes as being linked with the Sea Peoples.
The discovery of the megalithic structures discovered at Nabta Playa (Nabta Lake) in the Egyptian Sahara has provided evidence for the existence of a sophisticated society in that area around 5000 BC. In the same region, near the Dakhleh Oasis, archaeologists have produced data that supports the idea that pre-Pharaonic Egypt had Desert Origins rather than being an importation from Mesopotamia or elsewhere(a).
Nabta Playa is not unique, in fact the largest megalithic ellipse in the world is to be found at Mezorah, 27km from Lixus in Morocco(b). It appears that the construction methods employed at both Mezorah and Nabta Playa are both similar to that used in the British Isles. An even more impressive site is Adam’s Calendar in South Africa which has been claimed as 75,000-250,000 years old.
I think we can expect further exciting discoveries in the Sahara leading to a clearer picture of the prehistoric cultures of the region and what connections there are, if any, with Plato’s Atlantis. In the meanwhile in the Eastern Egyptian Desert, Douglas Brewer, a professor of archaeology at the University of Illinois, has discovered over 1,000 examples of rock art, including numerous depictions of boats although the sites, so far undisclosed, are remote from water.
