  "Machen, however, showed literary promise, publishing in 1881 a long poem "Eleusinia" on the subject of the Eleusinian Mysteries."  

 I'm new to Wiki Editing so I hope this goes through. I just want to suggest that it'd be worthwhile to note that Eleusinia was self-published - this information can be found in any of the top biographies: Reynolds & Charlton; Sweetser; Valentine, as well as in 'Far Off Things.'    

 Further, citations are required for the following passage:  "He was deeply suspicious of science, materialism, commerce, and Puritanism, all of which were anathema to Machen's conservative, bohemian, mystical, and ritualistic temperament. Machen's virulent satirical streak against things he disliked has been regarded as a weakness in his work, and rather dating, especially when it comes to the fore in works such as Dr Stiggins. Similarly, some of his propagandistic First World War stories also have little appeal to a modern audience"  
 In the first instance the only critic I know of to suggest what has been termed "Machen's virulent satirical streak against things he disliked" is by S. T. Joshi in "Philosophy and Fiction." Discovering Classic Horror Fiction 1  p. 6. Unfortunatly Joshi's work is polemical at best, not really a strong source upon which to base such an assertion.  
 Second, a source that can demonstrate that his First World War stories are 'propagantistic' and that they have little appeal to a modern audience is required, two sources if need be the case.
