Don Juan is one of Byron's most outstanding achievements in his life. This long narrative poem with great momentum, superb views and outstanding art is rare in the history of world literature. This long poem perfectly combines romanticism and realism. The story begins in a broad social and historical background and ends with a series of conspiracy events. The poet commented extensively on the disadvantages of Europe and exposed the disadvantages of civilized society. There are descriptions of nature, incisive comments on various phenomena in the world, and satire and ridicule of reality. The whole poem is magnificent, smooth and ups and downs, and contains rich thoughts in exquisite artistic form. Shelley once praised: "There has never been such a work in English." Goethe even thought Don Juan was a masterpiece of genius.
