Hermetic Brotherhood of Light

The Hermetic Brotherhood of Light was a Fraternity that descended from the Fratres Lucis in the late 18th century (in turn, derived from the German Order of the Golden and Rosy Cross), and was the seed from which Ordo Templi Orientis (O.T.O.) ('Order of the Temple of the East' or 'Order of Oriental Templars') was created.
