<em>Columbus arrives as a supplicant at the court of Queen Isabella of Spain, hoping for cash and three tall ships. When the Queen asks him what he desires, he bows over her hand and murmurs, "Consummation." The Queen is offended. Columbus becomes known at Isabella's court for his colorful clothes and excessive drinking. The Queen plays with Columbus, permitting him familiarities, then banishing him to the stables and piggeries for forty days. "The search for money and patronage," Columbus says, "is not so different from the quest for love." Isabella claims Granada, the last redoubt of Arab Spain. Columbus gives up hope. He departs the court, passing long columns of Jews, who are being expelled from Spain. He dreams that Isabella is herself having a dream, in which she sees that all the known world is hers, but that she will never be satisfied by the possession of the known. Isabella's heralds arrive and tell Columbus that she has summoned him for his voyage--she saw a vision, and it scared her.</em>
