Book: The Mysteries Of Mithra by Franz Cumont
Cumont's work is generally considered to be the quintessential work on the Mithraic cult. His book presents a well researched and easily readably description of this religion. Mostly he focuses upon how the religion was spread in the Roman Empire, where it originated and some of its basic dogmas. However, if you are looking for a description of the secret initiation rituals you will have to look elsewhere. While he does mention these rituals in brief, there is no extensive description or analysis on them.The colorful Mithraic religion originated in Persia, enjoyed enormous popularity in Europe, and was ultimately destroyed by Christianity. This definitive treatment of Mithra by a leading authority on classical religions pieces together its mysteries: the principle characteristics of the god Mithra, the rituals, the teachings, the liturgy and much more.
