context) and the island of Sete Cidades, were usual geographic references that persisted in the proto-geography of the Atlantic. With the advent of the Age of Discovery, the visual references and number of voyages of discovery multiplied. One of the more consistent maps presented to King Afonso V of Portugal was from the Azorean, Fernão Teles (in 1473). This map showed a long coastline, with various islands, bays and rivers which the author declared were part of the fabled land of Sete Cidades. In reality, the map easily follows the northern coast of Brazil, between Maranhão and Ceará, with the Rio Parnaíba delta. The King, himself, was not totally convinced of the discovery, or did not consider Fernão Teles sufficiently creditable, and that the map only represented a reference that required proofs. Unhappy with the outcome, Teles insisted on the validity of Sete Cidades. He consulted a Genovese cosmographer Paolo del Pozzo Toscanelli (1398–1492), who declared that Antilla and the island of Sete Cidades existed along the margins of the Atlantic. In his famous letter, Toscanelli placed the mythical lands of Sete Cidades near the Azores: "The island of Antillia was discovered by the Portuguese, and now when it is sought it is not found. In this island are people who speak the Spanish tongue, and who in the time of King Roderick are believed to have fled to this island from the barbarians who at the time invaded Spain. Here dwelt an archbishop with six other bishops, each of whom had its own particular city. Wherefore this island is called by many 'seven cities.' These people live most piously in the full enjoyment of all the riches of this time." In 1476, the Teles's petition of royal authentication was accepted, but no expeditions were sent by the donatario. Of the better documented expeditions, the Fleming Ferdinand van Olm (also known in Azorean history as Fernando de Ulmo or Fernão Dulmo) captained an expedition to rediscover the lost kingdoms of Sete Cidades. Ironically, Fernando de Ulmo was then married to one of the daughters of Fernão Teles and lived on one of the islands of the Azores when, in 1486, he received authorization from King João II of Portugal to begin his expedition. In partnership with Afonso do Estreito, a Madeirense, he organized his voyage, with the co-financing of the Royal Court, in order to conquer and subjugate the islands.
