Silk in poetry

Be in my hands heavenly silk,
Intricate light of the sun and the moon, Clear, dim or dark silk
Starless night, sun and moon,
I would silk spread out at your feet,

But I - poor, and only my dreams,
And I have spread my dreams under your feet,
Go easy, you tread on my dreams ...

William Butler Yeats, from the source, "He dreams of celestial silks"
