Throughout his collective writings, the author H. P. Lovecraft makes frequent use of the words "obscene" and "blasphemous" in order to convey a sense that something is the object of disgust or that it is debased in some fashion.
As an example, in his 1936 novella At the Mountains of Madness he uses the word "blasphemous" (or its derivatives) ten times both to describe things that unsettled the narrator due to their basic nature, and things which the narrator came to believe were devolved forms of art and culture that had once existed at a higher level.
there was something vaguely but deeply unhuman in all the contours, dimensions, proportions, decorations, and constructional nuances of the blasphemously archaic stonework. [Chapter 6]
Is there any greater meaning that may be gleaned from Lovecraft's choice of these words, either in the context of Lovecraft's view of the world, or in the context of the use of these words in the time in which Lovecraft lived? Or where they purely stylistic in choice?
