"Translated by Dr. M. Doreal Some 38,000 years ago, THOTH, an Atlantean Priest king, autobiographically wrote the legend famous Emerald Tablets. In later time, Thoth became known as the God of Wisdom, the Keeper of the Records, the Mighty Magician, and Hermes, the Thrice born."

"The Emerald Tablet is said to be a tablet of emerald or green stone inscribed with the secrets of the universe. The source of the original Emerald Tablet is unclear; hence it is surrounded by legends. The most common story claims that the tablet was found in a caved tomb under the statue of Hermes in Tyana, clutched in the hands of the corpse of Hermes Trismegistus himself."

"The Emerald Tablet of Thoth, also referred to as the Emerald Tablets of Hermes, is thought to be the work of Hermes Trismegistus ("Hermes the Thrice-Great"), a legendary Egyptian sage or god, variously identified with the Egyptian god Thoth and/or the Greek god Hermes created to chronicle his journeys from the times of Atlantis until the times of Khem (Egypt)."

"Molded out of a single piece of green crystal, the Emerald Tablet carries a prophetic message full of hidden meaning. Although its true origin is lost in legends that go back over 10,000 years, the wondrous artifact was translated into Greek by Alexandrian scholars and actually put on display in Egypt in 330 BC. Around the year 400 AD, it was reportedly buried somewhere on the Giza plateau to protect it from religious zealots who were burning libraries around the world at that time. Many believe the tablet still lies hidden there."
