Percy Bysshe Shelley

“ He wrote to me several letters from Switzerland, which were subsequently published, together with a Six Weeks' Tour, written in the form of a journal by the lady with whom his fate was thenceforward indissolubly bound... In the early summer of 1816, the spirit of restlessness again came over him, and resulted in a second visit to the Continent... During his absence he wrote me several letters, some of which were subsequently published by Mrs. .Shelley; others are still in my possession... During his stay in Switzerland he became acquainted with Lord Byron. ”
