This poem from Clark Ashton Smith (CAS) includes the wonderful description "faint castanets": a perfect verbal rendition of the sound made by the rattles of the deadly venomous snake.
Also particularly effective is the phrase "stirless brake", capturing the perfect stillness preceding a potential moment of high drama. Taken together, these elements create an almost cinematic palette, reminiscent of the best moments of the stylish western genre films of years past.
