The Grotesque Axe of Dayo Tanchen is a 1801 years old piece made by Dayo Tanchen, a lumberjack living in Ambohimanga.
Considering its age and the quality of the work, people consider it of some 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 348, Thutmose Tanchen, the owner, made use of it in Amud to empower the Tanchen family. Now it is lost, or broken, we will never know.
