Read "Wizard's Love" at The Eldritch Dark
http://www.eldritchdark.com/writings/poetry/660/wizard%27s-love
This poem from Clark Ashton Smith (CAS) was unpublished in his lifetime, but saw print the year after his passing in one of Roy Squires' beautiful letterpress editions, The Hill of Dionysus: A Selection (1962).
It's not a standout among CAS' poems, although it is steeped with the fantastic and supernatural imagery that are so characteristic of his work:
In desperate, forgotten wizardries,
With signs and sigils of dead goeties,
And evocations born of blood and pain
But deemed for ever vain.
It's a fun read, but ultimately somewhat forgettable given the many superior verses to be found throughout CAS' poetic corpus.
