An astronomer has traced the origins of the earliest known descriptions of what would become the constellations of today's Zodiac to the region which once held the Assyrian cities of Ninova and Asur.
The descriptions, which include more than 200 astronomical observations, are written in cuneiform on a collection of clay tablets, known as MUL.APIN. The tablets are known to have been made in Babylon in around 687 BC, but archaeologists believe they are only transcriptions of much earlier records.
