The Decayed Bottle of Jaakobah Montmirail is a 1579 years old piece made by Jaakobah Montmirail, a con artist living in Mecca.
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 Sufism.
This piece doesn't exist, but as a legend. It is said that in the year 880, Charlotte Montmirail, the owner, made use of it in Barcelona to empower the Montmirail family. Now it is lost, or broken, we will never know.
