The Mysteries of Mithra. Echoes from the Gnosis
An early twentieth-century theosophical account of Mithraism, its origins, mysteries, symbolism and initiatory traditions, published as the fifth volume of Mead’s Echoes from the Gnosis series.
The New Mithraeum
The fifth volume in the Echoes from the Gnosis series of eleven volumes edited by Mead and published by the Theosophical Publishing Co. The series of small volumes "was drawn from, or based upon, the mystic, theosophic and gnostic writings of the ancients" so as to make available to a wider audience "some echoes of the mystic experiences and initiatory lore of their spiritual ancestry."
