Read "The Nevermore-To-Be" at The Eldritch Dark:
This poem from Clark Ashton Smith (CAS) is a darkly beautiful paean to a (presumably) brief dalliance:
Lady, let us pluck delight
Only from a forfeit night,
From the bedded myrtles strewn
'Neath a never-risen moon.
The use of tetrameter with strong end rhymes reminds me of the witches' chants from Macbeth ("Double, double, toil and trouble; / Fire burn and cauldron bubble."). That association, along with the repetition of the word "sorcery" in the first and last stanzas, lends "The Nevermore-To-Be" a touch of the supernatural, giving it CAS' own distinct artistic stamp.
