Introduction to the Elements of Millettarian Symbology is the sixty-ninth instalment in the Little Blue Book Series and comprises the seventh discourse of the Tridoxy, which is itself the third disquisition of the Omnidoxy, the founding treatise of Astronism. Within this single-discourse publication, there exists an extensive list of items regarding the terminology of Astronic symbology (which includes both Millettarian and Astronist symbology). 
 
The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
