Ancient Babylon lies in the part of the world now known as Iraq.
Researcher Mathieu Ossendrjver made the startling discovery while translating cuneiform writing on clay tablets from the ancient cities of Mesopotamia and Uruk. The University of Berlin professor published his findings in this month’s issue of Science.
The tablets date from around 400 to 50 BCE and reference sophisticated calculations used to track the position of Jupiter. Babylonian astronomers computed the planet’s displacement as an area in time-velocity space.
Ossendrjver found detailed instructions and calculations carved into about 400 clay tablets. Basically, “the method relies on determining the area of a trapezium under a graph.”READ MORE: Solo Crash Friday Night Closes Moraga Road, Cuts Power to Hundreds
Historians believed heretofore the method was invented by 14th-century European astronomers.
According to Ossendrjver, the zodiac, another Babylonian concept, was also used to track the planets.
The Babylonians worshiped Jupiter, as did the Egyptians and the Greeks. They considered the giant planet a manifestation of their patron God, Marduk.
