pumice and lava
The Red, White and Black stone which Plato said had adorned the buildings of its port city, have led Atlantis seekers to eagerly follow up this apparently obvious clue. However, as with so many aspects of the Atlantis story, this particular detail does not provide us with anything like a clear pointer to any specific location.
Jürgen Spanuth relates[015.125] how the ancient Canarians decorated their temple with red, white and black rock, the colours of tufa, pumice and lava. The cliffs of Santorini are also known to display red, white and black rock. These three materials are frequently found in the vicinity of volcanoes(b) and may be considered a valuable clue to the location of Atlantis.*[However, this combination of rock colours is not exclusive to volcanic localities as Jim Allen has demonstrated at Pampa Augallas in the Andes and Peter Daughtrey at his Silves site in Portugal[0893.120].]*
Although Atlantis was destroyed by an earthquake, volcanoes are often located in the same general region such as in the Central Mediterranean which is both seismically and volcanically very active and, in my opinion, the prime candidate as the home of Atlantis. This view is endorsed by Plato himself who twice (Tim.25b & Crit.114c) told us that the territory of the Atlantean alliance stretched from North Africa as far as Tyrrhenia in Italy. I further propose that this was on a north/south axis.
Jim Allen has found the same three rock colours at his Bolivian site and further afield, Ian Wilson points out that red, white and black bricks were used extensively in Çatal Hüyük. Not to be excluded, Diaz-Montexano has produced photos on his website of pre-Roman structures near Gibraltar that incorporate red, white and black blocks in their construction. Jonas Bergman has indicated that similarly coloured stone is to be found in Morocco. Other locations include the Azores, Algeria and Sardinia.
Some(a) have sought to link the red, white and black of the Nazi swastika with Plato’s reference.
