Answer 1

he discovers a Navigation, geography and above all astronomy were the main focus of interest of the Renaissance scientist, at a time when the general population still subscribed to the idea that the Earth was flat. Nicholas of Cusa had dared to suggest that the Earth spun around its own axis. Aeneas Sylvius Piccolomini before he became pope (Pius II) had noted how, while on a visit to Scotland, the day at the winter solstice lasted only four hours, unlike for example in Italy.

But the heliocentric model that would so forcefully be promoted by Bruno and later Galileo was not an invention of the Renaissance scholar; they – and their descendants – looked to Egypt as the homeland of all knowledge, from which they had inherited it. They had merely reacquired this knowledge. Both Johannes Kepler (1571-1630), the discoverer of the laws of planetary motion (which to this day are still the basis for space travel) and Sir Isaac Newton (1642-1727) said that they got their ideas from Egypt. There is actually factual evidence that Newton derived his physics – including gravity – from the Hermetic cosmology. Copernicus, who publicly promoted the heliocentric model in the 16th century, also identified the Hermetic literature as his source of information and inspiration.
