The Decayed Door of Yadidatum Kalinou is a 1357 years old piece made by Yadidatum Kalinou, a builder living in Hecatompylos.
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 719, Nethaneel Kalinou, the owner, made use of it in Hecatompylos to empower the Kalinou family. Now it is lost, or broken, we will never know.
