Machen’s popularity in 1920s America has been noted, and his work was an influence on the development of the pulp horror found in magazines like Weird Tales and on such notable fantasy writers as James Branch Cabell, Clark Ashton Smith, Robert E. Howard, [11] Frank Belknap Long (who wrote a tribute to Machen in verse, "On Reading Arthur Machen"), [12] Donald Wandrei, [13] David Lindsay[10] and E. Charles Vivian.
