The _Epipsychidion_ tells us of the poet's love adventures and gives us his beautiful dream of love. In _Alastor_ he had depicted his longing for love; the poem was written in 1815 at the time he was living with Harriet Westbrook; it shows how lonely he felt and how he longed for love. In _Epipsychidion_, where he speaks of his lying "within a chaste, cold bed," he says that he had not the full measure of love from his second wife. Hence he took refuge in building a fanciful isle where he satisfies his love with Emilia Viviani. In this great poem Shelley gives us a glimpse into his polygamously inclined unconscious. He states his philosophy of free love in the poem. As physical desire was a strong factor in Keats's one solitary love, the trait most characteristic of Shelley was his polygamous instinct. This is present in the unconscious of the male, and society has tried to eradicate it by marriage. We all know that there has never been complete success in this direction. The instinct which is repressed bursts forth especially when the marriage has not been successful, or when the man does not love his wife in full measure, though as the world is aware it breaks out even in cases where he does love. Neither of Shelley's two marriages gave him the real love he sought. He wanted other women to live in his household. He invited Miss Titchener to live with him and Harriet Westbrook, and he had Jane Clairmont, his wife's half sister, who fell in love with him, live with them. He thought he would be happy with Miss Viviani, but was disillusioned with her soon, and then his polygamous instinct made Mrs. Jane Williams the object of his affections. Yet Shelley led a chaste, upright life and did not satisfy his instincts for polygamy; instead, he wrote poetry. He created fantasies because of his repressions, and gave us the beautiful day dream closing the _Epipsychidion_. Mrs. Williams inspired some of the greatest lyrics in the language. The painful poem to her husband beginning with the words, "The serpent is shut out from paradise," tells how he flies because Mrs. Williams's looks stir griefs that should sleep and hopes that cannot die. The world owes to Shelley's attachment for Mrs. Williams such poems as, _Rarely, Rarely, Comest Thou, Spirit of Delight_, _One Word Is too Often Profaned_, _When the Lamp is Shattered_, _Oh, World! Oh, Hope! Oh, Time!_ _Rough Wind, That Moanest Loud_, _With a Guitar, To Jane_, _To Jane--the Invitation_, _To Jane--the Recollection_, _Remembrance_, _Lines Written in the Bay of Lerici_, and _The Magnetic Lady to Her Patient_. Here are a dozen poems that every lover of Shelley knows, yet they are the outpourings of the poet's love for another man's wife, written because he could not attain that love and satisfy his polygamous instincts. Had these instincts been satisfied, these beautiful poems would have been lost to the world.
