Robert von Ranke Graves (July 24, 1895 – December 07, 1985)
The butterfly, the cabbage white,
(His honest idiocy of flight)
Will never now, it is too late,
Master the art of flying straight,
Yet has — who knows so well as I? —
A just sense of how not to fly:
He lurches here and here by guess
And God and hope and hopelessness.
Even the aerobatic swift
Has not his flying-crooked gift.
