During the Age of Exploration, there were many remarkable explorers and sailors. Possibly the most famous explorer of that time was Christopher Columbus. He was the Italian explorer who "discovered" America. His voyage(s) would launch centuries of European expansion.
Ferdinand Magellan was a Portuguese explorer and the first person to complete a circumnavigation of the globe. This helped give the first true record of oceans and continents.
Amerigo Vespucci was an Italian explorer and the first European to sail across the equator in the “New World’s” waters. He also determined that the Earth was 25,000 miles around.
Aside from the explorers that I just mentioned, there were many more explorers who were really important and had impressive and history-changing accomplishments. Some of those explorers were John Cabot, Vasco da Gama, Francis Drake, etc.
All, or at least most, explorers wanted the 3 G's- gold, glory, and god. Each were desired by explorers back in the Age of Exploration. They wanted to get gold, receive glory, and spread religion.
There were many different ships and tools that were important and were used in the Age of Exploration. I think that the most important tool was the compass. It was super helpful to basically all explorers.
