opening of the text introduces a lecture that Garcia Redondo delivered before a distinguished audience at the Instituto Historico e Geographico de São Paulo in 1911. He reflects on his previous travels and how he was inspired to explore the history of discoveries made by the Portuguese. He references another author, Faustino da Fonseca, whose work asserts that Columbus and Pedro Alvares Cabral were not the first to discover these new lands, but were merely publicizing discoveries made by earlier Portuguese explorers. Garcia Redondo's goal in this conference is to advocate for the recognition of Portuguese priority in these significant historical events and to pay tribute to the exploration efforts of Portuguese navigators.
