"The Mysteries of Trhe Great Cross of Hendaye" reveals one of Western occultism's deepest secrets: The alchemical transformation of base metal into gold is also the transformation of the current Iron Age into the Golden Age. Based on the work of the enigmatic 20th-century alchemist Fulcanelli, authors Weidner and Bridges show how the greatest alchemical secret is that of time itself and that coded into an obscure monument in south-western France-the cross in the town square of Hendaye-is the imminent date of the apocalypse. The authors' explorations of this symbolism lead them from the cross of Hendaye to the western facade of the cathedral of Notre Dame in Paris, the Pyrenees, ancient Egypt, and the secret origins of Atlantis in Peru. They reveal that we are indeed living in a "fatal season" and that this season is intimately connected to our solar system's alignment with the galactic centre. The authors' in-depth examination of alchemy's connection with the coming end days also reveals that this astro-alchemical knowledge was part of the sacred science of the Egyptians and the Atlanteans, whose coded messages are, at last, deciphered to guide humanity to its future destiny. This work uses the work of 20th-century alchemist Fulcanelli to predict the date of the fatal season of the apocalypse. It shows how periodic galactic alignments may cause catastrophes on Earth. It examines how the secret of the centre of the galaxy reveals the true location of the lost civilisation of Atlantis. It reveals the alchemical secret of the imperishable Light Body of ancient Egypt deep within our DNA.
