New Map of the world in Europe

1450 - 1480

By mid 1400 a new physical view/ representation of the world is created. It was far more precise than before but it was also still incorrect. Based on his view of the map the world was way to small and Asia was to big. This caused some confusing for travelers because when travelers thought they were turning the corner of Portugal they were expecting to just end up in Asia. Turns out they were very wrong and showed that Asia wasn't as big as Ptolemy thought. At the time Europeans maps were dominated by religious views. They created a T-O maps. In this map format, Jerusalem was depicted at the center and east was oriented toward the map top. Viking explorations in the North Atlantic gradually were incorporated into the world view beginning in the 12th century.

But from that he discovered other parts of the world that no one knew about.

The invention of the caravel was important for trade to happen. It was not only a faster, more convenient way to get spices around it was also meant you had much more storage space to fit all your trading products. The caravel was first invented by Prince Henry of Portugal before it made its way to Europe.
