On August 3, 1492, Christopher Columbus set out on his first voyage to what came to be known as the New World. With three ships and a crew of ninety, Columbus hoped to find a western route to the Far East. Instead, the Nina, the Pinta, and the Santa Maria landed in the Bahaman Islands.
Christopher Columbus set sail in an era of maritime advances, charting his route with the aid of a mariner's compass, an astrolabe, a cross-staff, and a quadrant. The most popular map for mariners at the time was Ptolemy's Geography or Cosmography, printed in 1482 but originally compiled by the Alexandrian geographer, astronomer, and mathematician Claudius Ptolemy in the second century A.D.
