The mysteries of Freemasonry are many. One mystery is a clear and accurate account of its history and origin. One theory is that Freemasonry was passed down from the obscure Eleusinian Mysteries and Rites. This classic 1919 work by British Freemason, Dudley Wright explores the nature and customs of the Eleusinian Mysteries. This is a valuable work for any Freemason with a hunger to learn more of the many orders and rites which many play parts in the development of modern Freemasonry. Introduction by Joseph Fort Newton.
