The Decayed Rock of Gazualum Legrand-Ébut is a 4363 years old piece made by Gazualum Legrand-Ébut, a beggar living in Isfahan.
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 -2160, Publius Legrand-Ébut, the owner, made use of it in Troy to empower the Legrand-Ébut family. Now it is lost, or broken, we will never know.
