Read "Minatory" at The Eldritch Dark:
This poem from Clark Ashton Smith (CAS) really invokes the power of his chosen art form, rendered in quite a visceral fashion, beginning with the unambiguous title. It's interesting that he chooses to render the world of the Muse in such stark terms:
Dim Summanus, lord of night,
Is her moiling minister,
Demogorgon toils for her
In the darkling Infinite.
It's an unsettling vision, but I appreciate the warning embedded in these lines, that those who dismiss the Muse of literature and poetry will suffer the loss of some of the genuine richness of the human experience.
