1460-1526. Portuguese explorer. He set sail from Lisbon for the East Indies Mar 1500, and accidentally reached Brazil by taking a course too far W. He claimed the country for Portugal 25 Apr, as Spain had not followed up Vicente Pinzon's (c. 1460-1523) landing there earlier in the year. Continuing around Africa, he lost seven of his fleet of 13 ships (the explorer Bartolomeu Diaz being one of those drowned), and landed in Mozambique. Proceeding to India, he negotiated the first Indo-Portuguese treaties for trade, and returned to Lisbon July 1501.
