The Decayed History book of Akinyi Isatis is a 3924 years old piece made by Akinyi Isatis, a historian living in Aksum.
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 Ancient Egyptian religion.
This piece doesn't exist, but as a legend. It is said that in the year 1214, Karima Isatis, the owner, made use of it in Istanbul / Constantinople / Byzantium to empower the Isatis family. Now it is lost, or broken, we will never know.
