Atlantis – Manly P. Hall

From Wikipedia:

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.

Atlantis – Diodorus Siculus

Per Wikipedia:

Diodorus Siculus (/?da???d??r?s ?s?kj?l?s/Greek: Δι?δωρος Σικελι?τηςDiodoros Sikeliotes) or Diodorus of Sicily was a Greekhistorian. He is known for writing the monumental universal historyBibliotheca historica, much of which survives, between 60 and 30 BC. It is arranged in three parts. The first covers mythic history up to the destruction of Troy, arranged geographically, describing regions around the world from Egypt, India and Arabia to Greece and Europe. The second covers the Trojan War to the death of Alexander the Great. The third covers the period to about 60BC. The title Bibliotheca, meaning ‘library’, acknowledges that he was drawing on the work of many other authors.

I’ve found a passage in Diodorus Siculus’ Library of History that describes a large land mass beyond the Pillars of Heracles that could be ancient Atlantis or America.  Here is what he said:

For there lies out in the deep off Libya an island of considerable size, and situated as it is in the ocean it is distant form Libya a voyage of a number of days to the west.  Its land is fruitful, much of it being mountainous and not a little being a level plain of suprassing beauty. Through it flow navigable rivers which are used for irrigation, and the island contains many parks planted with trees of every variety and gardens in great multitudes which are traversd by streams of sweet water; on it also are private villas of costly construction, and throughout the gardens banqueting houses have been construcred in a setting of flowers, and in them the inhabitants pass their time during the summer season, since the land supplies in abundance everything which contributes to enjoyment and luxury.

And, speaking generally, the climate of this island is so altogether mild that it produces in abundance the fruits of the trees and the other seasonal fruits for the larger part of the year, so that it would appear that the island, because of its exceptional felicity, were a dwelling-place of a race of gods and not of men. – Diodorus Siculus, The Library of History Book 3, pages 145-146.

I don’t believe this describe ancient America.  I believe it describes an ancient memory of Atlantis.

Atlantis – Plato

Per Wikipedia:

Plato (/?ple?to?/;[1]GreekΠλ?τωνPlát?n “broad”pronounced [plá.t??n] in Classical Attic; 428/427 or 424/423 – 348/347 BC) was a philosopher and mathematician in Classical Greece, and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, especially the Western tradition.[2]Unlike nearly all of his philosophical contemporaries, Plato’s entire oeuvre is believed to have survived intact for over 2500 years, and he is arguably one of the greatest, if not the greatest, writer in the entire Western canon.[3][4]

From Plato’s writing, we see a description of Atlantis:

At that time, as we said, Atlantis was an island larger than Libya and Asia put together, though it was subsequently over whelmed by earthquakes and is the source of the impenetrable mud which prevents the free passage of those who sail out of the straits into the open sea.  – Plato, Timaeus and Critias, page 131.
