Canto XV
The company of women. Lady Adeline is at risk of losing her honour, because of her apparent relation with Don Juan, whose passive, seductive manner is deceptive, because he never seems anxious to consummate the seduction; and, being personally modest, Don Juan neither brooks nor claims superiority. To thwart the social disgrace suggested by the appearance of sexual impropriety, Lady Adeline advises marriage to Don Juan, with which suggestion he agrees, but acknowledges that he usually is attracted to married women. In effort to deduce a suitable match for him, Lady Adeline deliberately omits mention of Aurora Raby, who is a Catholic, sixteen-year-old girl most suitable to pair and marry with Don Juan. Although attracted to Aurora, because she is purer of heart than the other women Lady Adeline mentioned, the adolescent girl reminds Don Juan of Haidée, the daughter of the pirate Lambro, who sold Juan into slavery at Constantinople The narrator then describes the elaborate dinner at which Don Juan is seated between Aurora and Lady Adeline. Initially laconic, Aurora soon warms to the spirit of the occasion, and contributes conversation during dinner.
Canto XVI
Seduced by a ghost. Smitten by her beauty, Don Juan thinks of Aurora when retiring to his rooms; that night, he walks the hall outside his rooms, viewing the paintings that decorate the walls. Hearing footfalls in the hallway, he sees a friar in cowl and beads, and asks if it be ghost or dream; despite the figure's pacing, the hood hides the face from Don Juan. In the morn, Don Juan's pale face turns Lady Adeline pale. Noticing the response of her hostess, the Duchess of Fitz-Fulke gives a hard-eyed look to Don Juan, whilst the adolescent Aurora looks at him "with a kind of calm surprise".
Lady Adeline asks if he is ill; Lord Henry says that Don Juan saw the “Black Friar” pace the hallway at night, and then tells of the “spirit of these walls”, who was often seen in the past, but not of late. That on honeymoon with Lady Adeline, he saw the ghost of the Black Friar haunt the halls of the house. Accompanying herself with a harp, Lady Adeline sings the story of the ghost of the Black Friar; Aurora is silent, whilst Lady Fitz-Fulke appears mischievous. The narrator suggests that Lady Adeline sang to dispel Don Juan's dismay.
Canto XVII
Truncated story. When Lord Byron died in 1824, the epic satire Don Juan was incomplete, and the concluding canto XVII featured little mention of the protagonist, Don Juan, and many mentions of the literary rivals, enemies, and critics who moralistically objected to Byron’s perspectives of people, life, and society; the critical gist was: “If you are right, then everybody's wrong!” In self-defence, Byron the poet lists people who were considered revolutionaries in their fields of endeavour — such as Martin Luther (1483–1546) and Galileo (1564–1642) — whose societies saw them as being outside the cultural mainstream of their times. Canto XVII concludes at the brink of resuming the adventures of Don Juan, last found in a “tender moonlit situation” with the Duchess of Fitz-Fulke, at the end of canto XVI.
