Don Juan is a satiric poem by Lord Byron, based on the legend of Don Juan, which Byron reverses, portraying Juan not as a womanizer but as someone easily seduced by women. It is a variation on the epic form. Byron himself called it an "Epic Satire" (Don Juan, c. xiv, st. 99). Modern critics generally consider it Byron's masterpiece, with a total of more than 16,000 lines of verse. Byron completed 16 cantos, leaving an unfinished 17th canto before his death in 1824. Byron claimed he had no ideas in his mind as to what would happen in subsequent cantos as he wrote his work. When the first two cantos were published anonymously in 1819, the poem was criticized for its 'immoral content', though it was also immensely popular. Byron was a rapid as well as a voluminous writer. Nevertheless, the composition of his great poem, Don Juan, was coextensive with a major part of his poetical life. He began the first canto of Don Juan in the autumn of 1818, and he was still at work on a seventeenth canto in the spring of 1823. The poem was issued in parts, with intervals of unequal duration. Interruptions in the composition and publication of Don Juan were due to the disapproval and discouragement of friends as well as the publisher's hesitation and procrastination. Canto I. was written in September 1818; Canto II. in December-January, 1818-1819. Both were published on 15 July 1819. Cantos III. and IV. were written in the winter of 1819-1820; Canto V., after an interval of nine months, in October-November 1820, but the publication of Cantos III., IV., V. was delayed till 8 August 1821. In June 1822, Byron began to work at a sixth, and by the end of March, 1823, he had completed a sixteenth canto. But the publication of these later cantos, which had been declined by John Murray, and was finally entrusted to John Hunt, was spread over a period of several months. Cantos VI., VII., VIII., with a Preface, were published on 15 July; Cantos IX., X., XI on 29 August; Cantos XII., XIII., XIV., on 17 December 1823; Cantos XV., XVI. on 26 March 1824. It has been said that the character of Donna Inez (Don Juan's mother) was a thinly veiled portrait of Byron's own wife, Annabella Milbanke (daughter of Sir Ralph Milbanke). Many of Byron's remarks and reflections on the motive behind his poem are humorous paradoxes, provoked by advice and opposition. For instance, writing to Thomas Moore, he says, "I have finished the first canto of a poem in the style and manner of Beppo, encouraged by the good success of the same. It is meant to be a little quietly facetious upon every thing. But I doubt whether it is not-at least as far as it has gone-too free for these very modest days." Critical opinion aligned itself with the opinion that the poem was "too free," however, a month after the two first cantos had been issued, Byron wrote to Murray, "You ask me for the plan of Donny Johnny; I have no plan-I had no plan; but I had or have materials.... You are too earnest and eager about a work never intended to be serious. Do you suppose that I could have any intention but to giggle and make giggle?-a playful satire, with as little poetry as could be helped, was what I meant." After the completion but before the publication of Cantos III., IV., V., in a further letter to Murray, he writes, "The Fifth is so far from being the last of Don Juan, that it is hardly the beginning. I meant to take him the tour of Europe, with a proper mixture of siege, battle, and adventure, and to make him finish as Anacharsis Cloots in the French Revolution.... I meant to have made him a Cavalier Servente in Italy, and a cause for a divorce in England, and a Sentimental 'Werther-faced' man in Germany, so as to show the different ridicules of the society in each of these countries, and to have displayed him gradually gate and blase, as he grew older, as is natural. But I had not quite fixed whether to make him end in Hell, or in an unhappy marriage, not knowing which would be the severes
