In 1501–1502, one of these Portuguese expeditions, led by Gonçalo Coelho (and/or André Gonçalves or Gaspar de Lemos), sailed south along the coast of South America to the bay of present-day Rio de Janeiro. Amerigo Vespucci's account states that the expedition reached the latitude "South Pole elevation 52° S", in the "cold" latitudes of what is now southern Patagonia (possibly near the Strait), before turning back. Vespucci wrote that they headed toward the southwest and south, following "a long, unbending coastline" (apparently coincident with the southern South American coast). This seems controversial, since he changed part of his description in the subsequent letter, stating a shift, from about 32° S (Southern Brazil), to south-southeast, to open sea; maintaining, however, that they reached 50°/52° S (if it was by his own decision or by D. Manuel's censors who had to pressure him to alter his account, because he had revealed far too much to Lorenzo de' Medici and into the public domain, is unknown).
