Sumerian Star Chart. Sky Map of Ancient Nineveh. c.3300 BCE. Reproduction of a Sumerian star map or “planisphere” recovered in the late 19th century from the 650 BCE underground library of Ashurbanipal. Long thought to be an Assyrian tablet, computer analysis has matched it with the sky above Mesopotamia in 3300BC and proves it to be more ancient Sumerian origin. The tablet is an “Astrolabe”, the earliest known astronomical instrument.
