"Là Ci Darem La Mano", Wixel/Freni/Davis, Covent Garden

In his exhaustive study Musical Allusions in the Works of James Joyce, Zack Bowen posits that nearly every one of Leopold Bloom's personality traits is reinforced with some kind of musical reference throughout the novel. His masochism, Bowen claims, is underscored by the 9 different references to 'Là Ci Darem La Mano'. He writes:

...it becomes in Bloom's mind symbolic of the liaison of Boylan and Molly. As Giovanni has lured the almost willing Zerlina, so Boylan will succeed with Molly. If Blazes is the amorous Don, and Molly is Zerlina, then Bloom must assume the role of the jealous and avenging Masetto.

(That's one approach!)
