They were coming very near the upper air,
And a sudden madness seized him, madness of love,
A madness to be forgiven if Hell but knew
How to forgive; he stopped in his tracks, and then,
Just as they were just about to emerge
Out into the light, suddenly, seized by love,
Bewildered into heedlessness, alas!,
His purpose overcome, he turned, and looked
Back at Eurydice. And then and there
His labor was spilled and flowed away like water.
—From "Orpheus and Eurydice," Virgil, Georgics, IV, II trans. David Ferry
