Guillermo Dupaix (1750-1817/8) was born in the Duchy of Luxembourg and became a captain in the service of the King of Spain made made three Royal expeditions to Mexico in 1805, 1806 & 1807 to study the monuments of that country. He was accompanied by José Luciano Castañeda a professor of drawing and architecture with the National Museum, whose drawings in the expeditions’ reports were considered more valuable than Dupaix’s text.
Dupaix concluded that the monuments at Monte Alban, El Tajin and Palenque had been built by the citizens of Atlantis.
Jean-Frédérick Waldeck (1766-1875) was a French explorer and artist. He spent time in Central America recording Mayan temples and glyphs in a style that suggested possible links with various ancient European and Asian civilisations. It is also claimed that he linked the Maya with both Egypt and Atlantis.
Waldeck was always secretive regarding aspects of his life and by his own estimate was 109 when he died, the image here claims to have been taken when he was 107 years old!
Charles Etienne Brasseur de Bourbourg (1814-1874) was born in Bourbourg, near Dunkirk, France. He entered the priesthood and in 1845 he left for Canada and was for a short time professor of ecclesiastical history at Quebec. He worked as a missionary in Mexico and Central America where he developed an intense interest in the native South Americans and their origins. In 1859 he published a history of the Aztecs.
Hubert H. Bancroft (1832-1918), the American historian, noted[1319.125-132] that initially Brasseur was highly sceptical of the reality of Atlantis, but as his studies deepened he became an enthusiastic believer.
Brasseur de Bourbourg’s ability to track down rare manuscripts was legendary. He studied the thoroughly flawed interpretation of Mayan hieroglyphics by Bishop Diego de Landa, produced in the 16th century. He concluded that the Maya were originally from Atlantis, based on Plato’s description of Atlantean culture. This view was expressed in his 1868 book, Quatre Lettres sur le Méxique.
Brasseur also translated local languages into Roman script and perhaps his most important contribution was a French translation of the Popul Vuh, sacred book of the Quiché branch of the Maya, which was published in 1861. An English translation is now available on the Internet(a).
Nigel Davies has revealed that Brasseur, as well as Lord Kingsborough (1795-1829), concluded that the native Americans were in fact the Ten Lost Tribes of Israel. This idea had been suggested by centuries earlier by Diego de Landa (1524- 1579), the Franciscan bishop of Yucatán.
Iin the mid-19th century, Brasseur proposed that Atlantis had existed on a large landmass in the Atlantic of which Hispaniola is a remnant. He believed that this vast peninsula extended to the vicinity of the Canaries. This idea was based on his own, largely incorrect, interpretation of Mayan glyphs. The American Hyde Clarke and the Guatemalan doctor Paul Felix Cabrera shared similar location theories.
Jason Colavito has pointed out that Brasseur was probably the first to suggest the possibility that some form of Pole Shift led to the destruction of Atlantis(b). This idea was published in 1873 and is available in an English translation by Colavito(c).
After what he thought was reference to a flooded land called Mu, one of his last conclusions was that Mu and Atlantis were the same and that Mu was the correct name for the flooded land. This fantasy led Augustus le Plongeon to revise this theory, suggesting that refugees from both Mu and Atlantis were the founders of the Mayan civilisation.
Paul Felix Cabrera was an 18th century Guatemalan doctor who proposed in 1796 that Hispaniola was the site of Atlantis and that the Phoenicians had settled the Caribbean and Mesoamerica. He proposed that the ruins at Palenque are support for this assertion. The entire text is available on-line at the Oliver Cowdery link below(a) .
