Jay Stuart Wakefield (1943) is a zoologist who has worked as a newsletter and book editor, and in

property management. Like Reinoud, his interest in megalithic prehistory was inspired by childhood reading of Heyerdahl’s books. His father Richard’s high school graduation address in 1932 entitled The Antiquity of Man in North America began a lifetime of father-son reading, and archaeological exploration. Their coastal and offshore sailing experience has been helpful in this research.

Jay and Reinoud have visited sites together and worked together on this manuscript for four years in their respective libraries on opposite sides of the world. This is the first time any of this material has been printed in English. The authors are clearly indebted to those who

precede them, particularly Mrs. E. Shee Twohig. whose magnificent out-of -print catalogue of European petroglyphs has been indispensable, and her figures frequently used in this work. The authors also wish to acknowledge Dr. Gerard F. IJzereef, Professor of Archaeology of the University of Amsterdam, for his support.

From the data we have derived from these sites. the thinking and achievements of prehistoric man are being brought to light. Now it may be possible to further sort out the profuse stories and legends of the latpre historical period. There is a lot of work to be done both in literature and in the field.
