Bartholomew Columbus (Spanish: Bartolomé Colón; Italian: Bartolomeo Colombo; c. 1461 - 1515) was the younger brother of explorer Christopher Columbus. In the 1470s Bartolomeo was a mapmaker in Lisbon, the principal center of cartography of the time, and conceived with his brother the "Enterprise of the Indies," a scheme to break the Portuguese grip on the remunerative Oriental trade by sailing west to reach East Asia.
