The book begins with an argument between Cleopatra, Queen of Egypt, and Julius Caesar. As a triumphant invader, Caesar belittles the Egyptian people and suggests that Egypt, as a realm, is past its best. Infuriated, Cleopatra makes a wager with Caesar promising to build a new palace in Alexandria within three months. Cleopatra summons Edifis, who claims to be the best architect in Egypt. She promises Edifis that if he builds the palace on time he will be covered with gold; if he fails, he will be a meal for the sacred crocodiles.
