Read "Estrangement" at The Eldritch Dark:
It seems that this poem from Clark Ashton Smith (CAS) is a second version of the poem I read yesterday, "In Autumn". Some of the lines from that poem show up verbatim in "Estrangement", making me suspect that the first poem was really a draft of this one.
And it's all to the good, since "Estrangement" is much the superior work, with the closing stanza particularly notable for its lyric beauty:
In vain the falling leaves caress
A lute among the roses lost;
And the frail touch of petals tossed
Will leave it mute and tremorless.
The image of the musical instrument abandoned and silent speaks volumes.
