“The Lucky,” by W. H. Auden (Part XV. of “The Quest”)

Suppose he’d listened to the erudite committee,
He would have only found where not to look;
Suppose his terrier when he whistled had obeyed,
It would not have unearthed the buried city;
Suppose he had dismissed the careless maid,
The cryptogram would not have fluttered from the book.

“It was not I,” he cried as, healthy and astounded,
He stepped across a predecessor’s skull;
“A nonsense jingle simply came into my head
And left the intellectual Sphinx dumbfounded;
I won the Queen because my hair was red;
The terrible adventure is a little dull.”

Hence Failure’s torment: “Was I doomed in any case,
Or would I not have failed had I believed in Grace?”
