The Cathedral of Notre Dame in Paris has many unique and exquisite attributes.
Even before entering the great stone edifice the doors grab attention. Not the doors so much as the hinges.
They are made from wrought iron by Biscornette who was a very mysterious worker. Legend has it no one ever saw him constructing the hinges. Reports went round that he had sold his soul to the devil to get him to help. The design is supposed to represent the Earthly Paradise.
An iron master named Gaegart broke off fragments of the iron to try and figure out how Notre Dame’s hinges were created. Some experts think that they are cast, and then treated with a file; others say they must have been created solely by casting, with no soldering. In any case, the secret will never be divulged, it died with Biscornette.
Do you have a secret method for doing something?
