Arthur Machen
Around 1890 Machen began to publish in literary magazines, writing stories influenced by the works of Robert Louis Stevenson, some of which used gothic or fantastic themes. This led to his first major success, "The Great God Pan". It was published in 1894 by John Lane in the noted Keynotes Series, which was part of the growing aesthetic movement of the time. Machen's story was widely denounced for its sexual and horrific content and consequently sold well, going into a second edition.

He also published works on the "Last Days of the Life of Jesus", on "Judaism in the Time of Christ", on "John of Damascus" (1879) and an "Examination of the Vatican Dogma in the Light of Patristic Exegesis of the New Testament". But he is chiefly famous for his "Geschichte der Römischen Kirche" ("History of the Church of Rome to the Pontificate of Innocent III") (4 vols, 1881–1893), a work of sound scholarship, based directly upon the authorities, the most important sources being woven carefully into the text. He also contributed largely to the "internationale theologische Zeitschrift", a review started in 1893 by the Old Catholics to promote the union of several National Churches on the basis of the councils of the Undivided Church, and admitting articles in German, French and English.
