Hendaye's Cyclical Cross: a coded calendar?

The so-called "Cyclical Cross" is an enigmatic monument located in the Basque town of Hendaye, in the French Pyrenees Atlantiques. Its esoteric symbolism was analyzed in the XNUMXs by Fulcanelli, the "last of the Alchemists", who saw in the Latin inscription on the arms of the cross and in the bas-reliefs on its pedestal the revelation of the Four Ages of humanity and the prophecy of the cataclysm next future that will come to put an end to the deadly Iron Age.
