Foster, Mark James
Mark James Foster runs a small London design agency(a) and is also an historical researcher who had an interesting website that is principally concerned with ancient Egypt. His first book was as co-author with Simon Cox on an A–Z of Atlantis. This small volume offers nothing new and is just a re-working of well-known material. Foster has also worked with Ralph Ellis on a number of articles(c).
*W.M. Flinders Petrie (1853-1942) investigated what he described as ‘trial passages’ near Giza’s Great Pyramid. Foster has written an extensive article on them and in November 2017 he updated this article(d) in the light of the claimed discovery of previously unknown voids in the GP.*
