The Decayed Abacus of Abdul La flemmille is a 3950 years old piece made by Abdul La flemmille, a merchant living in Akkad.
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 Ancient Mesopotamian religion.
This piece doesn't exist, but as a legend. It is said that in the year -897, Dariush La flemmille, the owner, made use of it in Akkad to empower the La flemmille family. Now it is lost, or broken, we will never know.
