Wordsworth, Dorothy, and Coleridge then traveled to Germany in the autumn of 1798. The main effect on Wordsworth was that he became homesick. But he began to work on the important autobiographical piece "The Prelude". He also wrote a number of famous poems, including "the Lucy poems." He and his sister moved back to England, now to "Dove Cottage" in Grasmere in the Lake District, and this time with the poet Robert Southey nearby. Wordsworth, Coleridge, and Southey came to be known as the "Lake Poets". Through this period, many of his poems speak of death, endurance, separation, and grief.
