(ORDO NEWS) — Experts have discovered a clay tablet named Si.427 on the territory of Ancient Babylon. Its age is approximately 3700 years.
Presumably, the plate was used earlier by surveyors, because it shows a plan of the field, as well as measurements of the boundaries of the earth.
The tablet was made between 1900 and 1600 BC by the ancient Babylonians. Reported by The Guardian.
The tablet was found by specialists at the end of the 19th century. All this time, it was kept in one of the museums of Istanbul, until Daniel Mansfield accidentally saw it.
Together with colleague Norman Wildberger, they determined that it contains the oldest trigonometric table on the planet. Most likely, this find once had a practical application. It could be used either in geodesy or in construction.
The plate describes information using the well-known Pythagorean triplets. Scientists noted that a clear description of the field is provided, wetlands, the place where grain is to be threshed, and a nearby tower are marked.
The tablet discovered by experts is considered unique, because it shows the methods of calculus, which were then invented by Pythagoras only 1000 years after they were used in Babylon.
