Manly Palmer Hall (March 18, 1901 – August 29, 1990) was a Canadian-born authorand mystic. He is best known for his 1928 work The Secret Teachings of All Ages.
Manly P Hall refers to Atlantis in his book, The Secret Teachings of All Ages. In it he writes:
In the Critias, Plato describes in detail the divine foundation of the Atlantian empire, originally known as Poseidonis. The golden age preserved in myth an legend, when the gods walked with men, depicts the zenith of Atlantean civilization. The demigods of the ancient world were the Atlantians, to whom every civilized nation owes an incalculable debt of gratitude. In the British Museum there is a remarkable document -known as the Troano manuscript-which was written over 3,500 years ago by the Mayas of Yucatan containing an authentic account of the cataclysm which sank the continent of Atlantis. This priceless document contains the following statement according to the translation by Le Plungeon: “In the year 6 Kan on the 11th Mulac in the month Zac, there occurred terrible earthquakes, which continued without interruption until the 13th Chuen. The country of the hills of Mud, the land of Mu, was sacrificed; being twice upheaved it suddenly disappeared during one night, the basin being continually shaken by volcanic forces, Being confined, these caused the land to sink and to rise several times and in various places. At last the surface gave away and ten countries were torn asunder and scattered; unable to stand the force that caused the land to sink and to rise several times and in various places. At last the surface gave away and ten countries were torn asunder and scattered; unable to stand the force of the convulsions, they sank with their 64,000,000 inhabitants.” Before the Atlantean continent was submerged, the initiates of the Atlantean Mysteries, carrying with them the secret doctrines entrusted to their keeping, immigrated into Egypt and other parts of the earth where they would be safe from the impending catastrophe. Thus their secret teaching-with its priceless value of subsequent ages-was preserved. They established centers of learning and promulgated the code, clothed in the language of symbolism, to such as they deemed worthy to receive it. – Manley P. Hall, The Teaching of the Ages, page XLI.
