Here are some key points:
* Early Influences: The Portuguese had been sailing for centuries before their famous Age of Exploration. They were influenced by the Phoenicians, Greeks, Romans, and Arabs, learning shipbuilding, navigation techniques, and trade routes.
* Prince Henry the Navigator (1394-1460): While not directly establishing a school, Prince Henry was a crucial figure in the development of Portuguese navigation and exploration. He established a school in Sagres, which focused on astronomy, cartography, and navigation. This attracted scholars and skilled sailors, fostering innovation and knowledge sharing.
* Navigational Innovations: Portuguese explorers and cartographers made significant advancements in navigation techniques. They perfected the astrolabe, developed the compass, and created detailed charts.
* Royal Patronage: Portuguese monarchs, particularly King John II, actively supported the development of sailing and exploration. They provided funding for expeditions, established maritime institutions, and encouraged the advancement of navigation skills.
Therefore, rather than a single founder, the Portuguese sailing school was a product of a cumulative effort involving royal patronage, the work of scholars and sailors, and the constant pursuit of knowledge and advancement in navigation.
