Renaissance inspires exploration as early as the 1400s.
God: Desire to spread Christianity
Glory: Desire to become a hero for discovering new places
Gold: Desire to become rich and powerful (individually & nationally)
Advances in technology made the voyages of discovery possible
Biggest Problem: European ships could not sail against the wind
Shipbuilders built new vessels: Caravel
Adopted triangular sails from the Arabs: this allowed the ships to sail against the wind
Ship became sturdier and shallower (allowing them to sail closer into shore)
Astrolabe: an instrument sailors used to determine their location at sea (told how far north or south they were from the equator
Sextant: replaced the astrolabe in the 1700s, sailors could determine both latitude and longitude
Compass: an instrument which allowed sailors to track direction accurately (adopted from the Chinese)
Navigation Schools: created by Prince Henry, Portugal, in 1419 – map and instrument makers, shipbuilders, scientists, and
sea captains all attended his school
