The secret of the 3500-year-old tablet was revealed; The world’s oldest map works like a GPS!

According to National Geographic; For decades, archaeologists considered a 3,500-year-old clay tablet to be merely a rudimentary and imprecise drawing. But new research has revealed a surprising truth: this piece of clay, slightly larger than the palm of an adult human, is actually a detailed and scaled map of the ancient city of Nippur in Mesopotamia, which could be the world’s oldest urban engineering plan. Discovered during 1899 excavations in present-day Iraq, the tablet had puzzled researchers for decades about how to read it.

The turning point of this story took place in the 1970s. At that time, McGuire Gibson, an archaeologist at the University of Chicago, observed aerial photographs of the Nippur region and noticed a striking correspondence between the lines on the tablet and the remains of the city walls. Subsequent excavations at the sites indicated by the tablet revealed the remains of fortifications, and this ancient map was proven to be accurate “to within 10 percent” and covered the entire city with an area of ​​about 1.3 square kilometers.

But how did its creators achieve such accuracy? Augusta McMahon, a professor of Mesopotamian archeology at the University of Chicago, says people of the time were skilled surveyors and used primitive tools like knotted ropes and measuring rods. According to him, probably some kind of basic trigonometry was used to calculate the angles, but making such a map required incremental measurements and patient and exhausting calculations.

The purpose of making this map is another mystery. Historical evidence shows that the city of Nippur was abandoned centuries before the date of making this tablet. Then a new dynasty of kings called the Kassites took over. Johannes Hackl, a professor of Assyrian studies at the Friedrich Schiller University Jena in Germany, where the tablet is kept, explains that the Mesopotamian kings “considered their duty to be constructive.” The Kasi began to rebuild the destroyed parts of Nippur, and there is a strong possibility that this clay tablet was not just a map, but an engineering plan and road map for the reconstruction of the city; The oldest city blueprint ever discovered in the world.
