This poem from Clark Ashton Smith (CAS) was unpublished in his lifetime, and is not available on The Eldritch Dark, so here's the complete text:
from a garden of darkest amaranth:
the pools of sunset, coloring
my fevered fantasy like some rich wine;
The author also wrote a Spanish version of this poem with the title "Memoria Rosa".
CAS is well known for his extensive English vocabulary, and "Red Memory" is something of an exercise in words and phrases that suggest red coloration:
- rich wine
- talismanic rubies
- hyacinthine eyes
- Vermillion splendor
- the blood / a god was bleeding
- sanguine trees
- a god's ichor
("Amaranth" often suggests the flower of the same name that features blooms tending towards the purple, but it is also a name for red dye).
My point in highlighting the phrases above is not to demonstrate that CAS was capable of using a thesaurus, but rather that in constructing a poem focused on a particular color, he needed to avoid simply repeating the word "red" over-and-over, else risk creating a work that would be quite tedious to read.
He rose to the challenge with phrases like "a god's ichor" which preserve the color-sense he is conveying while enriching the poem with additional associations that expand its scope.
