Tales about undiscovered cities filled with vast riches were prevalent in medieval times and several of them remain today. The story of Cibola, the seven cities of gold, originated in 713 AD when the Moors were invading Spain and Portugal and the Iberian peninsula was under Arab control. Portuguese bishops carried away gold and priceless religious artifacts from the city of Oporto and sailed away to a secret location that was only accessible by boat. But no one knew where this mysterious place could be. When explorers set foot in the Americas and observed the natives with gold trinkets, it renewed interest in the old Cibola legends. Perhaps, the lost cities of gold were located in the Americas.
