The Decayed Mould of Daria Praetorius is a 3105 years old piece made by Daria Praetorius, a brick maker 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 Folk religion.
This piece doesn't exist, but as a legend. It is said that in the year 424, Farid Praetorius, the owner, made use of it in Isfahan to empower the Praetorius family. Now it is lost, or broken, we will never know.
