Nationality words link to articles with information on the nation's poetry or literature (for instance, Irish or France). Events This year is known as the "Year Without a Summer" after Mount Tambora had erupted in the Dutch East Indies the previous year and cast enough ash into the atmosphere to block out the sun and cause abnormal weather across much of Northern Europe and the Northeastern United States. This pall of darkness inspires Byron to write his poem "Darkness" in July. Lord Byron separates from his wife and in April leaves England to tour continental Europe (never returning), settling in the summer in Switzerland, at the Villa Diodati by Lake Geneva; in late May he meets, and soon becomes friends with, the poet Percy Bysshe Shelley, and Shelley's wife-to-be Mary Godwin. Regular conversation with Byron has an invigorating effect on Shelley's poetry. While on a boating tour the two take together, Shelley is inspired to write his Hymn to Intellectual Beauty. Shelley, in turn, influences Byron's poetry. This new influence shows itself in the third part of Childe Harold's Pilgrimage, which Byron is working on, as well as in Manfred, which he writes in the autumn of this year. In late August Percy Bysshe Shelley and Mary Wollstonecraft Godwin return to England from Switzerland, taking with them some of Byron's manuscripts for his publisher. Shelley is introduced to John Keats in Hampstead towards the end of the year by their mutual friend, Leigh Hunt, who is to transfer his enthusiasm from Keats to Shelley. December 30 — Shelley marries his mistress Mary Wollstonecraft Godwin in London following the suicides on October 9 of her half-sister, Fanny Imlay (by laudanum in Swansea), and on December 10 of his pregnant estranged first wife, Harriet (by drowning in The Serpentine).
