This is a derangement (an exercise from Wingbeats II) of a fragment from Edna St. Vincent Millay.
In memory
No more the broken bird beats
golden; the once-ivory box is
spoken: all your words are lovely.
Restore the secret of earth:
chemistry shall never talk
but of your music.
– from Edna St. Vincent Millay, “Memorial to D.C.: Elegy”
