The wide range of subject matter presented here testifies to the vitality and growth of the Order during our last century. Some of the essays in the present volume offer accounts of O.T.O. history--covering prominent figures such as British Columbia Lodge No. 1 founder Charles Stansfeld Jones (Frater Achad), violinist Leila Waddell, and book publisher Albert W. Ryerson. Others discuss more modern history such as a look at the development of the UK Grand Lodge. One paper describes the influence of Aleister Crowley's magick--and C. S. Jones' interpretation of it--on Malcolm Lowry's novel Under the Volcano. Another tracks some six hundred performances of Crowley's dramatic ritual cycle of The Rites of Eleusis by O.T.O. bodies worldwide. There is an extensive history and analysis of the teachings and structure of the Universal Brotherhood (UB), which attracted Frater Achad during a spiritual crisis and in which he served for three decades. A meditation on the recent past and development of O.T.O. under the leadership of Hymenaues Beta is offered by the National Grand Master of Australia, while the Frater Superior's Representative in Canada discusses the development of the magical memory. Other essays consider what the writings and experiences of O.T.O.'s founders tell us about topics ranging from political and ethical considerations in the New Aeon, the early history of A\A\ and O.T.O. before their adoption of the Law of Thelema, and the importance of the relationship between these two allied orders.
