Graham Hancock (born 2 August 1950) is a British writer and journalist. Hancock specialises in unconventional theories involving ancient civilisations, stone monuments or megaliths, altered states of consciousness, ancient myths and astronomical/astrological data from the past. One of the main themes running through many of his books is a posited global connection with a "mother culture" from which he believes all ancient historical civilisations sprang.
Hancock describes himself as an "unconventional thinker who raises controversial questions about humanityâ€™s past". Prior to 1990 his works dealt mainly with problems of economic and social development. Since 1990 his works have focused mainly on speculative connections he makes between various archaeological, historical, and cross-cultural phenomena.
His books have sold more than five million copies worldwide and have been translated to 27 languages.
