The Decayed Theorem of Ku-enlila Tetumra is a 2128 years old piece made by Ku-enlila Tetumra, a mathematician living in Jerusalem.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with central asian patterns and some symbols pertaining to Yazdanism.
This piece doesn't exist, but as a legend. It is said that in the year -73, Zehra Tetumra, the owner, made use of it in Jerusalem to empower the Tetumra family. Now it is lost, or broken, we will never know.
