Thurlings, Lambertus (Bert)
Lambertus (Bert) Thurlings is a Dutch electrical engineer who is particularly interested in the study of ancient mysteries from a technological point of view. This led to the writing of a two book set, in Dutch, entitled Verborgen Geheimen van de Mensheid (Hidden Secrets of Mankind). Unfortunately Thurlings, like von Däniken, is keen to suggest prehistoric astronauts as the source of ancient technologies, rather than of the inherent ingenuity of man. He expands on this in a short e-book(b).
He also proposes 7910 BC as the date of the destruction of Atlantis. He promotes his ideas with a Dutch/English website(a).
