Salve Dominique and thank you for all the additional parallels you mentioned. Since I wrote this little article, I have indeed found new examples here and there. Quite a fascinating subject, isn't it? I hadn't heard much about the links between Mithraism and Monachism, though. I have read about survivals of Mithraism in the Middle Ages. Certainly
Richard Veymiers has written about it. I think there is even a filmed conference on the web where he explores the subject in depth, but I would love to know more about Monachism and Mithraism if you have more of it.
