The Decayed Abacus of Ilozumba Pion du cul is a 2092 years old piece made by Ilozumba Pion du cul, a merchant living in Katsina-Ala.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with african patterns and some symbols pertaining to Berber religion.
This piece doesn't exist, but as a legend. It is said that in the year -82, Ilozumba Pion du cul, the owner, made use of it in Katsina-Ala to empower the Pion du cul family. Now it is lost, or broken, we will never know.
