About the book (from Google):
This volume deals with the myths and legends of Babylonia and Assyria, and as these reflect the civilization in which they developed, a historical narrative has been provided, beginning with the early Sumerian Age and concluding with the periods of the Persian and Grecian Empires. Over thirty centuries of human progress are thus passed under review.
About the author (from Wikipedia):
Donald Alexander Mackenzie (1873 – 2 March 1936) was a Scottish journalist and folklorist and a prolific writer on religion, mythology and anthropology in the early 20th century.
He believed specifically that Buddhists colonised the globe in ancient antiquity and were responsible for spreading the swastika. In his Buddhism in Pre-Christian Britain (1928)’ he developed the theory that Buddhists were in Britain and Scandinavia long before the spread of Christianity.
