The Oronteus Finaeus map, 1531

One of the oldest known surviving copies of Ptolemy’s world map, which was compiled from his book “Geographia” which was written around 150 A.D.
One of the most intriguing things (as well as a crucial contribution to cartography) about this archaic map is the use of curved longitudinal and latitudinal lines along what seems to be the curved shape of the planet, demonstrating how aware ancient people were that they were living on a circular world, or at least one that wasn’t flat.
