The Lucy poems [SEP] Introduction
The Lucy poems are a series of five poems composed by the English Romantic poet William Wordsworth (1770–1850) between 1798 and 1801. All but one were first published during 1800 in the second edition of "Lyrical Ballads", a collaboration between Wordsworth and Samuel Taylor Coleridge that was both Wordsworth's first major publication and a milestone in the early English Romantic movement. In the series, Wordsworth sought to write unaffected English verse infused with abstract ideals of beauty, nature, love, longing and death. The poem was written during a short period while the poet lived in Germany. Although they individually deal with a variety of themes, as a series they focus on the poet's longing for the company of his friend Coleridge, who had travelled with him to Germany but took up residence separately in the university town of Göttingen, and on his increasing impatience with his sister Dorothy, who had travelled with him abroad.
