Found the following article online, use it to answer the question: What is the name of the person that Rinaldo drew his sword to attack?  The Crusader army under Goffredo is laying siege to Jerusalem, where the Saracen king Argante is confined with his troops. With Goffredo are his brother Eustazio, his daughter Almirena, and the knight Rinaldo. As Goffredo sings of the coming victory, Rinaldo declares his love for Almirena, and Goffredo confirms that she will be Rinaldo's bride when Jerusalem falls. Almirena urges Rinaldo to fight boldly and assure victory. As she departs, a herald announces the approach of Argante from the city. Eustazio surmises that the king fears defeat; this seems to be confirmed when Argante, after a grandiose entrance, requests a three-day truce to which Goffredo graciously assents. After Goffredo leaves, Argante ponders his love for Armida, the Queen of Damascus who is also a powerful sorceress, and considers the help her powers might bring him. As he muses, Armida arrives from the sky in a fiery chariot. She has divined that the Saracens' only chance of victory lies in vanquishing Rinaldo, and has the power, she claims, to achieve this. The scene changes to a garden, with fountains and birds, where Rinaldo and Almirena are celebrating their love. They are interrupted as Armida appears, and wrests Almirena from Rinaldo's embrace. Rinaldo draws his sword to defend his lover, but a black cloud descends to envelop Armida and Almirena, and they are borne away. Rinaldo mourns the loss of his loved one. When Goffredo and Eustazio arrive they comfort Rinaldo, and propose they visit a Christian magician who may have the power to save Almirena. Rinaldo, left alone, prays for strength.
