What is the theme in The House of Bernarda Alba by Federico Garcia Lorca?

One of the themes is beauty. Beauty—specifically the beauty of Adela, Bernarda's youngest daughter—is a source of conflict in the play. Beauty becomes corrupted, Lorca suggests, in an environment where people are not permitted to pursue their desires and passions. Pepe el Romano is passionate for Adela, but is bound by economic necessity to court Angustias instead. "If he were coming because of Angustias' looks, for Angustias as a woman, I'd be glad too," Magdalena comments, "but he's coming for her money. Even though Angustias is our sister, we're her family here and we know she's old and sickly, and always has been the least attractive one of us!" The daughters are all in such a state of repressed isolation that they will resent both Angustias, for having a suitor, and the beautiful Adela, for possessing Pepe as a lover.
