King Candaules by Théophile Gautier

Gyges, trembling and distracted with passion, had retired, following exactly the instructions of Candaules; and if Nyssia, through some unfortunate chance, had not turned her head ere taking her place upon the couch, and perceived him in the act of taking flight, doubtless she would have remained for ever unconscious of the outrage done to her charms by a husband more passionate than scrupulous.

Accustomed to the winding corridors of the palace, the young warrior had no difficulty in finding his way out. He passed through the city at a reckless pace like a madman escaped from Anticyra, and by making himself known to the sentinels who guarded the ramparts, he had the gates opened for him and gained the fields beyond. His brain burned, his cheeks flamed as with the fires of fever; his breath came hotly panting through his lips; he flung himself down upon the meadow-sod humid with the tears of the night; and at last hearing in the darkness, through the thick grass and water-plants, the silvery respiration of a Naiad, he dragged himself to the spring, plunged his hands and arms into the crystal flood, bathed his face, and drank several mouthfuls of the water in the hope to cool the ardour which was devouring him. Any one who could have seen him thus hopelessly bending over the spring in the feeble starlight would have taken him for Narcissus pursuing his own shadow; but it was not of himself assuredly that Gyges was enamoured.
