Read "In Thessaly" at The Eldritch Dark:
This poem from Clark Ashton Smith (CAS) was first published in the November 1935 issue of Weird Tales magazine.
In Greek myth, the region of Thessaly has a number of legendary associations, including a reputation for being the haunt of witches. CAS draws powerfully on this vein, particularly in the last stanza:
And the black lote in Thessaly
Its juices dripped unceasingly
Above the rotting mouth of me;
And worm and mould and graveyard must
And roots of cypress, darkly thrust,
Transformed the dead to utter dust.
By placing this poem in the realm of Greek myth, and by invoking Apuleius' ancient Roman novel Metamorphoses, CAS elevates a rather simple concept to something imbued with the flavor of dark legend and the thaumaturgical mysteries of the early historical era.
