Spherical Earth
- abstract: The concept of a spherical Earth dates back to ancient Greek philosophy from around the 6th century BC, but remained a matter of philosophical speculation until the 3rd century BC when Hellenistic astronomy established the spherical shape of the earth as a physical given. The Hellenistic paradigm was gradually adopted throughout the Old World during Late Antiquity and the Middle Ages.
