Alsemero

Alsemero is a nobleman from Valencia who falls in love with Beatrice. He immediately postpones his voyage to Malta to declare his love for her. Alsemero is an honorable man. When he finds out that Beatrice is betrothed to Alonzo but would sooner marry him, Alsemero, he wants to challenge Alonzo to a duel. But Beatrice refuses to allow this. When Jasperino informs him that he and Diaphanta have overheard suspicious conversations between De Flores and Beatrice, Alsemero gives her a potion that is supposed to reveal whether a woman is a virgin. Not a jealous man by nature, he does not want to think ill of his new bride and is relieved when she passes the test. When Beatrice is finally forced into confessing her crime to him, he is horrified and rejects her utterly.
