Classicly

The novel formally inverts Don Quixote: as the don mistakes himself for the knightly hero of a Romance, so Arabella mistakes herself for the maiden love of a Romance. While the don thinks it his duty to praise the Platonically pure damsels he meets (such as the woman he loves), so Arabella believes it is in her power to kill with a look and it is the duty of her lovers to suffer ordeals on her behalf.
