Christian O'Brien

Born in Fulham, O'Brien was educated at Tiffin Boys School, Kingston-upon-Thames and then went to Cambridge University where he read natural sciences, graduating in 1935.

He happened to be in England when the Second World War started, and so joined up in the Royal Engineers, eventually becoming a major after service in Italy and Tunisia.

After his retirement in 1970, O'Brien began researching and writing about ancient civilisations, taught himself how to read cuneiform,[2] and published three books on the subject.

"The Wandlebury-Hatfield Heath Astronomical Complex" described his surveying and discovering what he calls the Wandlebury Enigma or Line A Loxodrome, a claim which has not gained much acceptance.

In the book he presents his view that 13 stone circles and 86 ridge-top cairns were designed and built for complex observational astronomy by a group of itinerant sages with links to Sumer.
