"The later Spanish tales were largely caused by reports given by the four shipwrecked survivors of the failed Narváez expedition, <u>which included Álvar Núñez Cabeza de Vaca</u> and a black moorish slave named Esteban Dorantes, or Estevanico. Eventually returning to New Spain, the adventurers said they had heard stories from natives about cities with great and limitless riches.
