Ferdinand Magellan (1480-1521). Bold + stupid = ?
If there's a lesson to be learned from Magellan's life, it's that bold doesn't pair well with stupid.
Bruce Barcott, "They Get Around: A history of voyages around the world, starting in the 16th century", The New York Times Book Review, Dec. 30, 2012 (noting that "[w]hile stopping in the Phillipines, Magellan responded to a chieftain's insult with a rash show of force" and that he "died in the ensuing battle, run through with bamboo spears").
Bonus: "Drake realized he could travel light and pick up provisions along the way. And by pick up I mean steal."
