all we ever needed to do to rediscover that knowledge was to measure the height and base perimeter of the Great Pyramid and multiply by 43,200! How l… - Graham Hancock

At the entrance of one of the Hypogeum's painted rooms, the faint engraved impression of a large human hand, also arbitrarily assigned to the Neolithic, may still be seen. It 'has parallels in similar designs in Palaeolithic sites at Gargas, El Castillo, and particularly with Montespan in the Franco-Cantabrian region.' The impression shows a hand with six fingers [a condition known as Polydactyly that is also seen on at least one of the 'Fat Lady' figures on show in the National Museum of Archaeology].

Traditions, with all their folksy redolences, are relatively safe matters for scholars to speculate about. Maps and nautical charts on the other hand — especially accurate, sophisticated maps of the kind used by Guzarate to chart Vasco da Gama's course from Malindi to Calicut in 1498 — are quite another matter. If maps have indeed come down to us containing recognizable representations of Ice Age topography — as arguably may be the case with the depictions of India and of the long-submerged Sundaland peninsula by Cantino and Reinal and with the depiction of the 'Golden Chersonese' by Ptolemy — then prehistory cannot be as it has hitherto been presented to us.
If they are what they seem, such maps mean a lost civilization. Nothing more. Nothing less.

The Piri Reis map of 1513 features the western shores of Africa and the eastern shores of North and South America and is also controversially claimed to depict Ice Age Antarctica — as an extension of the southern tip of South America.
The same map depicts a large island lying east of the southeast coast of what is now the United States. Also clearly depicted running along the spine of this island is a 'road' of huge megaliths. In this exact spot during the lowered sea levels of the Ice Age a large island was indeed located until approximately 12,400 years ago. A remnant survives today in the form of the islands of Andros and Bimini. Underwater off Bimini I have scuba-dived on a road of great megaliths exactly like those depicted above water on the Piri Reis map.
Again, the implication, regardless of the separate controversy of whether the so-called Bimini Road is a man-made or natural feature, is that the region must have been explored and mapped before the great floods at the end of the Ice Age caused the sea level to rise and submerged the megaliths.
