Bernd Grathwohl was born in Spaichingen on 25 June 1972 and grew up in southern Germany. By profession he is a training manager in electronics and IT professions. Already during his childhood his interest in archaeology developed and grew with more than fifteen trips to Greece since the 1990s. These trips and the study of many books on the subject, but above all the inexplicable mysteries of the past ultimately inspired him to write books. His research focuses territorially on historical Greece and technically on satellite image research, its measurement and calculation. He programs tables to determine distances and geometries. This is his third book among many small publications and articles.
