Career
In London while still a young man, he inspired The Hermetic Brotherhood of Luxor in 1884, but seemed to have little to do with the day-to-day running of the organisation, or indeed its actual teachings (Chanel et al, Hermetic Brotherhood of Luxor). There is some dispute over whether Théon taught Blavatsky at some stage. The Mother in The Agenda says he did, Chanel et al. considers this unlikely, while K. Paul Johnson speculates in The Masters Revealed that the Theosophical adept Tuitit Bey might be based on Théon.
The Hermetic Brotherhood of Luxor claimed to have originated in Egypt in 1870 and been brought to England by Théon in 1884.
In 1885 Theon married Mary Chrystine Woodroffe Ware (Madame Alma Théon), and the following year the couple moved to Paris. However Theon would still go on frequent visits to Paris.
Theon gathered a number of students, including Louis Themanlys and Charles Barlet, and they established the "Cosmic Movement". This was based on material, called the Cosmic Tradition, received or perhaps channelled by T Théon"s wife.
They established the journal Cosmic Review, for the "study and re-establishment of the original Tradition".
The Mother mentions that Sri Aurobindo and Theon had independently and at the same time arrived at some similar conclusions about evolution of human consciousness without having met each other. The Mother"s design of Sri Aurobindo"s symbol is very similar to that of Theon"s, with only small changes in the proportions of the central square (Mother"s Agenda, volume 3, p 454, dated December 15, 1962). He fell into a deep depression, and cancelled the Cosmic Movement.
During this time he was cared for by his followers.
He recovered somewhat but never retained his former status. Théon died at Tlemcen on 4 March 1927.
