Countryman, Jack
Jack Countryman is the author of many books with Christian themes. He also wrote Atlantis and the Seven Stars[1312] in which he expressed qualified support for some of Ignatius Donnelly’s theories,*although, he identifies Atlantis as the biblical Tarshish.
However, for me, his book is marred by his promotion of the idea of genetic manipulation by extraterrestrials from the Pleiades (the seven stars in the book title).*
