In 1440, Portuguese shipbuilders developed the caravel, a highly maneuverable sailing ship ideal for coastal exploration and long voyages. The caravel's design allowed for greater speed and agility, facilitating the Age of Discovery as explorers navigated uncharted waters along the African coast and beyond. This innovation played a crucial role in expanding European maritime capabilities and establishing trade routes.

The introduction of the caravel ship in Portuguese exploration facilitated the Age of Discovery, inspiring epic poems like Camões' 'The Lusiads' celebrating Portuguese maritime achievements. This literary movement influenced numerous poets to explore themes of adventure and exploration in their own works.
