Freeman, Lawrence
Lawrence Freeman is the American author of Beyond The Pillars: a search for Antediluvian civilizations(a) in which he reviews almost every civilisation and prehistoric mystery that you ever heard of. He refers to Atlantis throughout the book, but in rather sceptical tones, with the nearest to a conclusion being that – “Atlantis may well have never existed, but if it did exist, then it was likely only as part of a worldwide antediluvian civilization that is now coming to light.”
