The Great God Pan
What is now the first chapter of the novella was published in 1890 in a magazine called "The Whirlwind", while what is now the third chapter of the book was published in the same magazine the following year as a standalone short story called "The City of Resurrections". Machen only viewed the two works as connected after they were finished. Once he decided the two stories were connected, Machen wrote the rest of "The Great God Pan" in a single evening save for its final chapter. Machen did not think of an ending for the tale for months, and in that time believed that the novella would remain unfinished forever. The last chapter was completed in June 1891. Machen sent the novella to the publisher Blackwood, who rejected it, deeming it a clever story that "shrink[s]...from the central idea." It was accepted by John Lane and published in 1894. When published as a book, "The Great God Pan" was accompanied by another Machen tale called "The Inmost Light" which also features a mad scientist and elements of science fiction. The book's cover was illustrated by Aubrey Beardsley.
TAN Books
TAN Books was founded in 1967, as "TAN Books and Publishers," in Rockford, Illinois by Thomas A. Nelson (not to be confused with the founder of the Bible-publishing firm Thomas Nelson) to keep in print books teaching the traditional Catholic faith in the wake of the upheaval in the Church that followed the Second Vatican Council. The company's name was formed from the initials of its founder. Over the next 40 years, TAN published hundreds of new and classic titles on theology, Scripture, Church history, traditional devotions (including St. Louis de Montfort's "Secret of the Rosary", printing more than 4 million copies), and the lives of the saints, many of which were reprints of titles published by such notable American Catholic publishers as Benziger Brothers and B. Herder Book Company.
