a session of the Brazilian Historic and Geographic Institute, when he asked if the discovery might have been intentional. Until the 1854 conference, the widespread presumption was that the discovery had been an accident. Early works on the subject supported this view, including História do Descobrimento e Conquista da Índia (History of the Discovery and Conquest of India, published in 1541) by Fernão Lopes de Castanheda, Décadas da Ásia (Decades of Asia, 1552) by João de Barros, Crônicas do Felicíssimo Rei D. Manuel (Chronicles of the most fortunate D. Manuel, 1558) by Damião de Góis, Lendas da Índia (Legends of India, 1561) by Gaspar Correia, História do Brasil (History of Brazil, 1627) by friar Vicente do Salvador and História da América Portuguesa (History of Portuguese America, 1730) by Sebastião da Rocha Pita. The first work to advocate the idea of intentionality was published in 1854 by Joaquim Noberto de Sousa e Silva, after Pedro II had opened the debate. Since then, several scholars have subscribed to that view, including Francisco Adolfo de Varnhagen, Capistrano de Abreu, Pedro Calmon, Fábio Ramos and Mário Barata. Historian Hélio Vianna affirmed that "although there are signs of the intentionality" in Cabral's discovery, "based mainly in the knowledge or previous suspicion of the existence of lands at the edge of the South Atlantic", there are no irrefutable proofs to support it. This opinion is also shared by historian Thomas Skidmore. The debate on whether it was a deliberate voyage of discovery or not is considered "irrelevant" by historian Charles R. Boxer. Historian Anthony Smith concludes that the conflicting contentions will "probably never be resolved". Forerunners Cabral was not the first European to stumble upon areas of present-day Brazil, not to mention other parts of South America. Norsemen reached North America and even established settlements, though these ended in failure sometime before the end of the 15th century. Christopher Columbus, on his third voyage to the New World in 1498, traveled along part of what would later become Venezuela. In the case of Brazil, it was once considered probable that the Portuguese navigator Duarte Pacheco Pereira had made a voyage to the Brazilian coast in 1498. This belief has since been dismissed, however, and it is now thought that he voyaged to North America instead. There is more certain evidence that two Spaniards, Vicente Yáñez Pinzón and Diego de Lepe, traveled along the northern coast of
