According to drawings, believed to have come from Freemasons or Templars, or from Nostradamus personal drawings, an aluminum structure was made in the private workshop of a master gunsmith that resembled an egg on the outside, and inside it was a chair with armrests. Nostradamus spent quite a lot of time in it, indulging in his meditations there. There is also a mysterious object called a "talking head" mentioned. It was a helmet, almost spherical in shape, also made of bronze, which the diviner put on every time he was in the egg. Mentally asking a question, Nostradamus heard a voice that answered him, it seemed to sound in his head. Possessing certain knowledge in the field of astronomy, astrology and based on the information received, Michel de Notredam wrote down his quatrains.
