The suspicion that European travellers in the Indian Ocean in the sixteenth century may from time to time have stumbled across charts and maps containing the remnants of a lost geography (perhaps even the maps of Marinus of Tyre, said to have been superior to those of Ptolemy) is intriguingly enhanced by the first of Alfonso de Albuquerque's two letters. It introduces a 'piece of a map' that Albuquerque has acquired in his travels in the Indian Ocean and that he is sending to King Manuel. The fragment, he explains, is not the original but was 'traced' by Francisco Rodrigues from: 'a large map of a Javanese pilot, containing the Cape of Good Hope, Portugal and the land of Brazil, the Red Sea and the Sea of Persia, the Clove islands [effectively a world map, therefore], the navigation of the Chinese and the Gores [an unidentified people, thought by some to be the Japanese, or the inhabitants of Taiwan and the Ryukyu archipelago] with their rhumbs and direct routes followed by the ships, and the hinterland, and how the kingdoms border on each other. It seems to me, Sir, that this was the best thing I have ever seen, and Your Highness will be very pleased to see it; it had the names in Javanese writing, but I had with me a Javanese who could read and write.

In 1512, in handwritten notes on an enigmatic map that he had prepared showing the newly discovered Americas, the Turkish Admiral Piri Reis offered an intriguing answer to all these questions — at any rate for the particular case of Christopher Colombus, the most recent and most renowned of the ancient Atlantic dreamers. Piri's note, one of many on the same map, is written over the interior of Brazil:
'Apparently a Genoese infidel, by the name of Columbus was the one who discovered these parts. This is how it happened: a book came into the hands of this Colombus from which he found out that the Western Sea [i.e. the Atlantic] has an end, in other words that there is a coast and islands on its western side with many kinds of ores and gems. Having read this book through, he recounted all these things to the Genoese elders and said, 'Come, give me two ships, and I shall go and find these places.' They said, 'Foolish man, is there an end to the Western Sea? It is filled with the mists of darkness.

Columbus therefore cheated on his calculations, as the examining faculty of the University of Salamanca quite correctly pointed out. He used the smallest possible circumference of the Earth and the greatest eastward extension of Asia he could find in all the books available to him, and then exaggerated even those. Had the Americas not been in the way, Columbus’ expeditions would have failed utterly.

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.

If the normal portolano is indeed derived from the lost atlas of Marinus of Tyre, then it follows that other high-quality maps of regions much further afield than the Mediterranean and the Black Sea, and indeed a world map, might also have been preserved by the Arabs — for we know from Ptolemy's testimony that other Marinus maps, including a world map, did once exist. It will therefore do no harm to keep an open mind to the possibility that the portolan world maps that began to appear during the century after the Carta Pisane, might also have been influenced by earlier 'Tyrian sea-fish' maps of Phoenician origin. Christopher Columbus, whose passionate belief in lands across the Atlantic lead to his 'discovery' of the New World, seems to hint at a Phoenician connection when he describes one of the inspirations for his journey:
'Aristotle in his book On Marvellous Things reports a story that some Carthaginian merchants sailed over the Ocean Sea to a very fertile island ... this island some Portuguese showed me on their charts under the name Antilia.'
Antilia first appears on a portolan chart of 1424. It is a mysterious presence there, a riddle.

Behind the maps of the sixteenth century lies another story—the change in geographical conceptions, mapmaking, and map usage that took place in the late Middle Ages. Pietro Vesconte, Cresques Abraham, Fra Mauro, Andrea Bianco, and Henricus Martellus Germanus were among the medieval cartographers who began to reshape the image of the world before Columbus sailed west.

The American who first discovered Columbus made a bad discovery.

In fourteen hundred ninety-two Columbus sailed the ocean blue and discovered America. Now, some have argued Columbus actually discovered the West Indies, or that Norsemen had discovered America centuries earlier, or that you really can't get credit for discovering a land already populated by indigenous people with a developed civilization. Those people are communists. Columbus discovered America.

The earth’s round, like an orange, but this map is like its skin, cut off in ovals, north to south, laid flat and stretched a bit at the top and bottom. A Dutchman called Mercator invented the way to do this accurately twenty years ago. It’s the first accurate world map.

The fact that our public space is dominated by images to the glory of white men, conquerors, and certain colonizers or slavers undoubtedly contributes to the sense that history celebrates the supremacy of the white race. The "discovery" of America by Christopher Columbus, regardless of the explorer's merits, reflects a Eurocentric view of the world. Wasn't it a continent that has essentially been 'discovered' since it was inhabited? His troops plundered the local wealth, enslaved the natives and spread unknown diseases.

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.

[T]he designer of a unified architecture is in a similar situation as the cartographers that set out to draw the first maps of the world, based on the reports of traders and explorers returning from expeditions into uncharted waters and journeys to unknown coasts.

It’s like, how did Columbus discover America when the Indians were already here? What kind of shit is that, but white people’s shit?

On the fourth voyage, Columbus sailed along the coast of Central America trying to find the mouth of the Ganges River. It wasn't there, somehow.
