While most commonly known for his commentaries on the Thelemic canon of Holy Books, Marcelo Motta authored a series of epistles entitled ÒTracts on Aquarian MasonryÓ, which form the corpus of his conception of the social application of Thelema. It is in these pamphlets that he tackles issues often talked about, but rarely studied by other Thelemites. Rarer than his Equinox V series, and even rarer than his Oriflamme series, these simple staplebound pamphlets fetch exorbitant fees on the antiquarian market. It is for this reason I have sought to reissue them here, with improved layout and typography.
