The object of the poem is to describe the progress of a libertine through life, not an unprincipled prodigal, whose profligacy, growing with his growth, and strengthening with his strength, passes from voluptuous indulgence into the sordid sensuality of systematic debauchery, but a young gentleman, who, whirled by the vigour and vivacity of his animal spirits into a world of adventures, in which his stars are chiefly in fault for his liaisons, settles at last into an honourable lawgiver, a moral speaker on divorce bills, and possibly a subscriber to the Society for the Suppression of Vice.  The author has not completed his design, but such appears to have been the drift of it, affording ample opportunities to unveil the foibles and follies of all sorts of men—and women too.  It is generally supposed to contain much of the author’s own experience, but still, with all its riant knowledge of bowers and boudoirs, it is deficient as a true limning of the world, by showing man as if he were always ruled by one predominant appetite.

In the character of Donna Inez and Don José, it has been imagined that Lord Byron has sketched himself and his lady.  It may be so; and if it were, he had by that time got pretty well over the lachrymation of their parting.  It is no longer doubtful that the twenty-seventh stanza records a biographical fact, and the thirty-sixth his own feelings, when,

Poor fellow! he had many things to wound him,
Let’s own, since it can do no good on earth;
It was a trying moment that which found him
Standing alone beside his desolate hearth,
Where all his household gods lay shiver’d round him:
No choice was left his feelings or his pride,
Save death or Doctors’ Commons.

It has been already mentioned, that while the poet was at Dr Glennie’s academy at Dulwich, he read an account of a shipwreck, which has been supposed to have furnished some of the most striking incidents in the description of the disastrous voyage in the second canto in Don Juan.  I have not seen that work; but whatever Lord Byron may have found in it suitable to his purpose, he has undoubtedly made good use of his grandfather’s adventures.  The incident of the spaniel is related by the admiral.

In the licence of Don Juan, the author seems to have considered that his wonted accuracy might be dispensed with.

The description of Haidee applies to an Albanian, not a Greek girl.  The splendour of her father’s house is altogether preposterous; and the island has no resemblance to those of the Cyclades.  With the exception of Zea, his Lordship, however, did not visit them.  Some degree of error and unlike description, runs indeed through the whole of the still life around the portrait of Haidee.  The fête which Lambro discovers on his return, is, however, prettily described; and the dance is as perfect as true.
