Tennyson has given the title of Oenone to a poem in which the deserted wife tells the story of the judgment of Paris. Hither came at noon Mournful Oenone, wandering forlorn Of Paris, once her playmate on the hills. Her cheek had lost the rose, and round her neck Floated her hair, or seemed to float in rest. She, leaning on a fragment twined with vine, Sang to the stillness, till the mountain-shade Sloped downward to her seat from the upper cliff. --Tennyson.
