The Secret Fire, or Flamma Reconditus, was a Greek translation of an Egyptian text written by Ini-Herit in 700 A.D., in the sunken city of Menouthis. Ini-Herit claimed to have deciphered a version of the Emerald Tablet (the legendary stone that fell from Lucifer's head when he was cast out of heaven) engraved by the magician Hermes Trismegistus (Hermes Thrice-Great).
