We can no longer think of the so-called Fertile Crescent of Sumeria as the cradle of civilization. What seems more likely from the large body of evid… - Graham Hancock

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.

We might feel very sure that there is no more to reality that the material world in which we live, but we cannot prove that this is the case. Theoretically there could be other realms, other dimensions, as all religious traditions and quantum physics alike maintain. Theoretically, the brain could be as much a receiver as a generator of consciousness and thus might be fine-tuned in altered states to pick up wavelengths that are normally not accessible to us.

Ancient Egypt, like that of the Olmecs (Bolivia), emerged all at once and fully formed. Indeed, the period of transition from primitive to advanced society appears to have been so short that it makes no kind of historical sense. Technological skills that should have taken hundreds or even thousands of years to evolve were brought into use almost overnight—and with no apparent antecedents whatever. For example, remains from the pre-dynastic period around 3500 BC show no trace of writing. Soon after that date, quite suddenly and inexplicably, the hieroglyphs familiar from so many of the ruins of Ancient Egypt begin to appear in a complete and perfect state. Far from being mere pictures of objects or actions, this written language was complex and structured at the outset, with signs that represented sounds only and a detailed system of numerical symbols. Even the very earliest hieroglyphs were stylized and conventionalized; and it is clear that an advanced cursive script was it common usage by the dawn of the First Dynasty.
