 In 1506, the "Gymnasium" obtained a French translation of the Soderini Letter, a booklet attributed to Amerigo Vespucci that provided a sensational account of four alleged Vespucci voyages to explore the coast of lands recently discovered in the western Atlantic.The "Gymnasium" surmised that this was the "new world" or the "antipodes" hypothesized by classical writers.The Soderini Letter gave Vespucci credit for discovery of this new continent and implied that newly obtained Portuguese maps were based on his explorations.
