VALDEVIEIRA, Miguel (val-day-ve-ay'-e-rah), Portuguese soldier, born in Portugal about 1480; died in Sao Vicente, Brazil, in 1540. He was a soldier in Cabral's expedition to Brazil in 1500, and for mutinous conduct was abandoned with one companion near the present site of Porto Seguro. They were adopted by the Tupi Indians, and afterward rendered great services to explorers. Valdevieira, who had reformed, entered the Franciscan order, and assisted in the foundation of Sgo Vicente, where he died. He left a valuable manuscript, "Viagem da provincia da Vera Cruz," in which he recounts his adventures with the Indians during his exile in the territory of Vera Cruz, as Cabral named the country at its discovery.
