The year 1793 saw the first publication of poems by Wordsworth, in the collections An Evening Walk and Descriptive Sketches. In 1795 he received a legacy of 900 pounds from Raisley Calvert and became able to pursue a career as a poet.
It was also in 1795 that he met Samuel Taylor Coleridge in Somerset. The two poets quickly developed a close friendship. In 1797, Wordsworth and his sister Dorothy moved to Alfoxton House, Somerset, just a few miles away from Coleridge's home in Nether Stowey. Together Wordsworth and Coleridge (with insights from Dorothy) produced Lyrical Ballads (1798), an important work in the English Romantic movement. The volume gave neither Wordsworth's nor Coleridge's name as author. One of Wordsworth's most famous poems, "Tintern Abbey", was published in this collection, along with Coleridge's "The Rime of the Ancient Mariner". The second edition, published in 1800, had only Wordsworth listed as the author, and included a preface to the poems. It was augmented significantly in the next edition, published in 1802. In this preface, which some scholars consider a central work of Romantic literary theory, Wordsworth discusses what he sees as the elements of a new type of verse, one that is based on the "real language of men" and avoids the poetic diction of much 18th-century verse. Wordsworth also gives his famous definition of poetry as "the spontaneous overflow of powerful feelings: it takes its origin from emotion recollected in tranquility", and calls his own poems in the book "experimental". A fourth and final edition of Lyrical Ballads was published in 1805.
