The oldest map in the world is from Iraq, by the Babylonians more than 4000 years ago. The map has been engraved on clay tablets. It shows a region in the form of a circle, these are the areas where King Sargon the Akkadian conquered with his armies. It includes Babylon, Ashur, the mountains in the north and the marshes to the south (2300 B.C). The triangles coming out of the diameter of the circle indicates a number of islands!
