tales in Danish from 1835, these German works were at least mainly based on collected folk tales, and the Grimms remained true to the style of the telling in their early editions, though later rewriting some parts. One of the brothers, Jacob, published in 1835 Deutsche Mythologie, a long academic work on Germanic mythology. Another strain is exemplified by Schiller's highly emotional language and the depiction of physical violence in his play The Robbers of 1781. Great Britain In English literature, the key figures of the Romantic movement are considered to be the group of poets including William Wordsworth, Samuel Taylor Coleridge, John Keats, Lord Byron, Percy Bysshe Shelley and the much older William Blake, followed later by the isolated figure of John Clare; also such novelists as Walter Scott from Scotland and Mary Shelley, and the essayists William Hazlitt and Charles Lamb.

The majority of the poems were by Wordsworth, and many dealt with the lives of the poor in his native Lake District, or his feelings about nature—which he more fully developed in his long poem The Prelude, never published in his lifetime. The longest poem in the volume was Coleridge's The Rime of the Ancient Mariner, which showed the Gothic side of English Romanticism, and the exotic settings that many works featured. In the period when they were writing, the Lake Poets were widely regarded as a marginal group of radicals, though they were supported by the critic and writer William Hazlitt and others. In contrast, Lord Byron and Walter Scott achieved enormous fame and influence throughout Europe with works exploiting the violence and drama of their exotic and historical settings; Goethe called Byron "undoubtedly the greatest genius of our century". Scott achieved immediate success with his long narrative poem The Lay of the Last Minstrel in 1805, followed by the full epic poem Marmion in 1808. Both were set in the distant Scottish past, already evoked in Ossian; Romanticism and Scotland were to have a long and fruitful partnership. Byron had equal success with the first part of Childe Harold's Pilgrimage in 1812, followed by four "Turkish tales", all in the form of long poems, starting with The Giaour in 1813, drawing from his Grand Tour, which had reached
