The circular clay tablet shown was discovered 150 years ago at
Nineveh the capital of ancient Assyria, in what is now Iraq. The tablet shows
drawings of constellations and pictogram-based text known as cuneiform which
was used by the Sumerians, the earliest known civilization in the world. For
decades scientists have failed to decipher the tablet. In 2008 two scientists,
Alan Bond and Mark Hempsell from Bristol University finally cracked the
cuneiform code. By using a computer program that can reconstruct the night sky
thousands of years ago. The two scientists were able to establish the tablet
was a night notebook of Sumerian astronomers and refers to the events in the
sky before dawn on the 29th of June 3123 BC (Julian calendar).
Interesting Fact: What makes this discovery even
more amazing is the tablet also shows a large object travelling along the
constellation of Pisces. The symbols show the trajectory of the object to an
error of one degree to hit Köfels Austria. Köfels is recognized as the area of
the largest rockslide in the crystalline Alps and has given rise to numerous
theories about the cause of the rockslide. There is no crater so to modern eyes
it doesn’t look as a meteor impact site should look. However from the
information gathered from the tablet, the trajectory explains why there is no
crater. The in-coming angle was very low (six degrees) so the scientists
theorize that the asteroid clipped a near by mountain called Gamskogel and this
caused the asteroid to explode before it reached its final impact point. To
explain how they were able to get this much information from this little tablet
is above my pay grade.
