How we cite our quotes: (Canto.Stanza)
Quote #1
His classic studies made a little puzzle,
Because of the filthy loves of gods and goddesses,
Who in the earlier days raised a bustle,
But never put on pantaloons or bodices (1.41)
Don Juan's mother isn't sure if she wants her son reading the classics of Western literature because the classics are often filled with sex and violence. Little does she know that by shielding her son from sexual knowledge, she's making him more likely to act on his budding desires.
Quote #2
Here ends this canto. —Need I sing, or say,
How Juan, naked, favoured by the night,
Who favours what she should not, found his way,
And reached his home in an unseemly plight? (1.188)
This classic scene shows Don Juan escaping naked into the night after Alfonso has found him (Juan) with his wife, Julia. Juan is obviously naked because he and Julia have been having adulterous sex.
Quote #3
Haidée and Juan were not married, but
The fault was theirs, not mine: it is not fair,
Chaste reader, then, in any way to put
The blame on me, unless you wish they were (3.12)
Byron admits that he has been writing about a sexual relationship where Juan and Haidée are not married, which would have been immoral during his time. But here he asks the audience not to blame him, since it was Don Juan and Haidée who made the decision to have sex.
