Outside Cleopatra's palace a youth and maiden are observed. They are evidently very much in love with each other. While conversing, the gates open, Cleopatra and Mark Antony come forth, accompanied by soldiers, dancing girls. Etc. He bids farewell to Cleopatra and, accompanied by a bodyguard, starts on his journey. The youth takes no further notice of his sweetheart, but gazes fascinated at Cleopatra, who, after waving farewell to Antony, re-enters the palace. The youth continues to gaze after Cleopatra, pushes his affianced aside, falls to his knees and kisses the step where Cleopatra stood. He then goes into the grounds, underneath her bedchamber, writes on a scroll of his ardent love, wraps the paper around his arrow and shoots it through the window. Inside the chamber Cleopatra and her servants are startled, take the arrow and read the note. Looking outside, nobody can be seen. Shortly afterward Cleopatra goes outside to the bathing pool, poises on the brink, when, looking toward a clump of bushes, she spies the lovesick youth. He is brought out and Cleopatra imperiously demands what his presence means. He is not abashed, but kneels and tells of his love. Cleopatra orders her attendants away, takes the youth and leads him off. When alone he again reiterates his love. Cleopatra orders her servants to bring wine, fruit, perfumes, etc. Dancing girls appear, execute a few manoeuvres, then leave. Cleopatra then rises and dances before the youth. A servant enters, delivers a message to the mistress, then departs. Cleopatra hands a goblet to the young man, who drinks its contents, then falls dead. Cleopatra bows over his body a moment, then springs up and sits on the throne as Mark Antony comes down the steps. He salutes and embraces Cleopatra, observes the corpse and demands an explanation. Cleopatra carelessly replies: "Just another slave l was experimenting on with poison."
