Christian O’Brien, (1915-2001) was a geologist and head of the Iranian oil industry until his retirement in 1970. He was convinced that Atlantis had been located in the Azores and has suggested a possible geographical outline of Atlantis based on the bathymetric data available for the region(c).
The O’Briens supported hyperdiffusion and proposed that ‘the Shining Ones’ better known as the Elohim in the Bible were responsible for the sudden development of agriculture, city states and monumental building some time before 8000 BC. Eventually, they developed colonies, spreading their knowledge which in due course was responsible for the great civilisations of Egypt, Asia and America.
>In The Megalithic Odyssey  O’Brien offers an overview of the many megalithic stone circles and cairns on Cornwall’s Bodmin Moor. However, from chapter 6 until the end, he takes his hobby-horse for a ride, offering a convoluted account involving an order of Sumerian ‘Sages’ who brought advanced knowledge to Egypt, Britain and Ireland and further afield. Along the way, they or their leaders are remembered by different names, Osiris, Tuatha dé Danann, Druids or in Mexico as Quetzalcoatl. O’Brien attributes the megaliths of Bodmin Moor to the influence of some of these Sages, probably the Tuatha dé Danann on their way to or from Ireland!<
Included in O’Briens contention was the idea that the biblical Garden of Eden, designated by him as ‘Kharsag’, had been located in what is now southern Lebanon. A paper(b) outlining this idea includes a criticism of Zechariah Sitchin’s translation of Sumerian texts.
O’Brien’s work is now carried on by Edmund Marriage, his nephew, through an extensive website(a).
