Juan Sebastián Elcano completed the first circumnavigation of the Earth in 1522, following Ferdinand Magellan's death during the voyage. This monumental expedition provided unprecedented insights into global geography and the interconnectedness of the world. Elcano's journey not only demonstrated the vastness of the Earth but also opened new trade routes and fostered cultural exchanges between distant lands.

Ferdinand Magellan's expedition, which completed the circumnavigation of the globe in 1522, proved the Earth's roundness and inspired epic poetry about adventure and discovery. Poets like John Milton later drew on these themes, exploring the human spirit's quest for knowledge and understanding of the world.
