The best-known lines in the latter poem are: "Most wretched men Are cradled into poetry by wrong; They learn in suffering what they teach in song." The reader may think that it is utterly insignificant whether the Julian poem was written about the first Harriet instead of the second, but this is just as important as to know that, let us say, Arthur Hallam, and not some one else, is the person mourned by Tennyson in _In Memoriam_. And we are enabled to learn the influence upon his work and ideas when we understand the nature of the earliest sex repression in the poet's life. This affair in Shelley's nineteenth year was of vast import; it made the Shelley we know, the enemy of society and the reformer. He hated intolerance, religion and monarchy because by his heterodoxy and the offence it gave to Harriet Grove's parents, he lost her; not to mention that he also lost his mother's love for his radical views. He saw the world steeped in error, and he believed this condition made him lose the love of his betrothed and of his mother. He wrote to Hogg that he would never forgive intolerance. "It is the only point on which I allow myself to encourage revenge; every moment shall be devoted to my object which I am able to spare." Here in the words of this youth we see the main factor which led to writing _Prometheus Unbound_ and _The Revolt of Islam_. His plans shaped themselves at the time of the jilting, and he never swerved from them. And in the opening stanzas of the eleventh canto of the Islam poem he again describes the agonies of his lost love, with Harriet Grove in mind, no doubt. This poem was written in the summer of 1817. Shelley then became an uncompromising reformer because he had suffered in love for his radical ideas; hence he would make it his aim to spread the views which he held so that in the future other lovers should not lose their sweethearts because of liberal notions. And in the _Ode to the West Wind_ Shelley's prayer is to spread his ideas over the universe. Though the poet wrote a few good poems to Harriet Westbrook and dedicated _Queen Mab_ to her, she had little or no influence on his life except to bring him sorrow because of her suicide. One of the few references to her in his later work is in the _Epipsychidion_, "And one was true--oh! why not true to me?" Stopford Brooke thinks this refers to Harriet Grove, but this is not likely, as Shelley continues, "there shone again deliverance," and he speaks of one who was to him like the Moon. The Moon was, of course, his second wife, Mary Godwin, who immediately succeeded Harriet Westbrook. II
