British literature time, Blake was generally unrecognised during his lifetime, but is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age. Among his most important works are "Songs of Innocence" (1789) and "Songs of Experience" (1794) "and profound and difficult 'prophecies' " such as "Visions of the Daughters of Albion" (1793), "The First Book of Urizen" (1794), and "Jerusalem: the Emanation of the Giant Albion" (1804–?20). After Blake, among the earliest Romantics were the Lake Poets, a small group of friends, including William Wordsworth (1770–1850), Samuel Taylor Coleridge (1772–1834), Robert Southey (1774–1843)
Robert Southey of Robespierre", Southey published his first collection of poems in 1794. The same year, Southey, Coleridge, Robert Lovell and several others discussed creating an idealistic community ("pantisocracy") on the banks of the Susquehanna River in America: Southey was the first to reject the idea as unworkable, suggesting that they move the intended location to Wales, but when they failed to agree the plan was abandoned. In 1799 Southey and Coleridge were involved with early experiments with nitrous oxide (laughing gas), conducted by the Cornish scientist Humphry Davy. Southey married Edith Fricker at St. Mary Redcliffe, Bristol, on 14 November 1795.
