Columbus didn’t set out to prove the earth was round.
Forget those myths perpetuated by everyone from Washington Irving to Bugs Bunny. There was no need for Columbus to debunk the flat-earthers—the ancient Greeks had already done so. As early as the sixth century B.C., the Greek mathematician Pythagoras surmised the world was round, and two centuries later Aristotle backed him up with astronomical observations. By 1492 most educated people knew the planet was not shaped like a pancake.
Columbus was likely not the first European to cross the Atlantic Ocean.
That distinction is generally given to the Norse Viking Leif Eriksson, who is believed to have landed in present-day Newfoundland around 1000 A.D., almost five centuries before Columbus set sail. Some historians even claim that Ireland’s Saint Brendan or other Celtic people crossed the Atlantic before Eriksson. While the United States commemorates Columbus—even though he never set foot on the North American mainland—with parades and a federal holiday, Leif Eriksson Day on October 9 receives little fanfare.
Nina and Pinta were not the actual names of two of Columbus’ three ships.
In 15th-century Spain, ships were traditionally named after saints. Salty sailors, however, bestowed less-than-sacred nicknames upon their vessels. Mariners dubbed one of the three ships on Columbus’s 1492 voyage the Pinta, Spanish for “the painted one” or “prostitute.” The Santa Clara, meanwhile, was nicknamed the Nina in honor of its owner, Juan Nino. Although the Santa Maria is called by its official name, its nickname was La Gallega, after the province of Galicia in which it was built.
