Short Treatise on (Modes of Use of) the Calendar

Madame Blavatsky (The Roots of Ritualism in Church and Masonry) Alesister Crowley (The Book of Lies) and Marcelo Ramos Motta (Letter to a Brazilian Mason) praised in the highest Jean-Marie Ragon's La Messe et ses Mystères Comparés aux Mystères Anciens (The Mass and its Mysteries Compared to the Ancient Mysteries). In that book Ragon had repeatedly cited his 1842 e.v. pamphlet Notice Historique sur le Calendrier as necessary to understanding that great work. This pamphlet important to understanding the esoteric side of Freemasonry has been translated into English and presented together with the original French text.
