Question: Which individual founded a religion throughout their lifetime, Aleister Crowley or John Millington Synge?
Context: The Magical Revival is a book written by British occultist Kenneth Grant, first published in 1972.  It is the first of his "Typhonian Trilogy", which comprises this work and two others—"Aleister Crowley and the Hidden God" (1973) and "Cults of the Shadow" (1975).  In this work, he first introduced his theory that American horror author H. P. Lovecraft's Cthulhu mythos was psychic revelation presented as fiction, an idea which he would elaborate and extend further in his later works.  This idea - that what is ostensibly presented as fiction is often a vehicle masking deeper realities - has precedence in the inclusion by Aleister Crowley of many works of fiction in the official reading syllabus of his mystical and magical order, the Argentum Astrum ; Grant's recognition of Lovecraft's value may be seen as simply a detailed continuation, an "updating" of this basic idea using material which Crowley simply hadn't had the opportunity to read.  Grant also claimed in this work that there was an unconscious connection between Lovecraft and occultist Aleister Crowley, arguing that both of them channeled their work from the same occult forces, although Lovecraft was not consciously aware of the alleged otherworldly sources of his literary inspirations. Edmund John Millington Synge ( ; 16 April 1871 – 24 March 1909) was an Irish playwright, poet, prose writer, travel writer and collector of folklore.  He was a key figure in the Irish Literary Revival and was one of the co-founders of the Abbey Theatre.  He is best known for his play "The Playboy of the Western World", which caused riots in Dublin during its opening run at the Abbey Theatre. Aleister Crowley ( ; born Edward Alexander Crowley; 12 October 1875 – 1 December 1947) was an English occultist, ceremonial magician, poet, painter, novelist, and mountaineer.  He founded the religion of Thelema, identifying himself as the prophet entrusted with guiding humanity into the Æon of Horus in the early 20th century.  A prolific writer, he published widely over the course of his life. (William) Denis Johnston (18 June 1901 – 8 August 1984) was an Irish writer.  Born in Dublin, he wrote mostly plays, but also works of literary criticism, a book-length biographical essay of Jonathan Swift, a memoir and an eccentric work on cosmology and philosophy.  He also worked as a war correspondent, and as both a radio and television producer for the BBC.  His first play, "The Old Lady Says "No!"" , helped establish the worldwide reputation of the Dublin Gate Theatre; his second, "The Moon in the Yellow River", has been performed around the globe in numerous productions featuring such actors as Jack Hawkins, Claude Rains and Errol Flynn, although not all in the same production.  He played a role in the 1935 film version of John Millington Synge's "Riders to the Sea". The Playboy of the Western World is a three-act play written by Irish playwright John Millington Synge and first performed at the Abbey Theatre, Dublin, on 26 January 1907.  It is set in Michael James Flaherty's public house in County Mayo (on the west coast of Ireland) during the early 1900s.  It tells the story of Christy Mahon, a young man running away from his farm, claiming he killed his father. Tramp Press is a publishing company founded in Dublin in 2014 by Lisa Coen and Sarah Davis-Goff.  It is an independent publisher that specialises in Irish fiction.  The company is named after John Millington Synge's tramp, a reference to the bold outsider. Riders to the Sea is a play written by Irish Literary Renaissance playwright John Millington Synge.  It was first performed on 25 February 1904 at the Molesworth Hall, Dublin, by the Irish National Theater Society.  A one-act tragedy, the play is set in the Aran Islands, Inishmaan, and like all of Synge's plays it is noted for capturing the poetic dialogue of rural Ireland.  The plot is based not on the traditional conflict of human wills but on the hopeless struggle of a people against the impersonal but relentless cruelty of the sea. The Confessions of Aleister Crowley : An Autohagiography, by Aleister Crowley (1875–1947), is a partial autobiography by poet and occultist Crowley.  It covers the early years of his life up until the mid-late 1920s but does not include the latter part of Crowley's life and career between then and his death in 1947. The Playboy of the Western World is a 1962 film version of the 1907 play written by John Millington Synge.  It was directed and co-written by Brian Desmond Hurst and stars Gary Raymond and Siobhán McKenna.  Filmed in County Kerry, the film features many of the Abbey Players.  The film was produced by the Four Provinces company created in 1952 by Hurst and Michael Morris, 3rd Baron Killanin who had previously produced John Ford’s "The Rising of the Moon" and "Gideon's Day". Deirdre of the Sorrows is a three-act play written by Irish playwright John Millington Synge, first performed at the Abbey Theatre by the Irish National Theatre Society in 1910.  The play is based on Irish mythology, in particular the myths concerning Deirdre and Conchobar.  The work was unfinished at the author's death in 1909, but was completed by William Butler Yeats and Synge's fiancée, Molly Allgood.
