Answer» The earliest reliably documented MENTION of the spherical Earth concept dates from around the 6th century BC when it appeared in ANCIENT Greek philosophy but remained a matter of speculation until the 3rd century BC, when Hellenistic astronomy established the spherical SHAPE of the Earth as a physical given. The paradigm was gradually ADOPTED THROUGHOUT the Old World during Late Antiquity and the Middle Ages.A practical demonstration of Earth's sphericity was achieved by Ferdinand Magellan and Juan Sebastián Elcano's expedition's circumnavigation(1519–1522). |
