And the eyes of all look upward seeing sign-word drawing nigh,
The stony wings of Egypt coming back across the sky; We hear the clinking tamborine of Miriam anew;
We believe in every miracle since Lindbergh flew the blue — The wonder of the long draw when the bowstring is a thread —
The beauty of a courage that can raise the wings of lead.
Venus Invisible and Other Poems (1928) - The Wings of Lead
