Read "Decadence" at The Eldritch Dark:
Clark Ashton Smith (CAS) seemed to be quite attracted to the notion of the world-weary artist, and that particular topical vein is at the heart of this poem. The closing lines are worth repeating:
How wearily, how humbly shall you crave
From the low Earth an everlasting grave,
And from the dust its ancient anodyne!
What else can the world-weary artist do but long for the sweet oblivion of death? It may be something of a cliché, but few writers have tackled it with the same eloquence that CAS brought to the task.
