4 unusual facts about Spherical Earth


Spherical Earth

Bishop Isidore of Seville (560–636) taught in his widely read encyclopedia, The Etymologies, that the Earth was round.

Knowledge of the sphericity of the Earth survived into the medieval corpus of knowledge by direct transmission of the texts of Greek antiquity (Aristotle), and via authors such as Isidore of Seville and Beda Venerabilis.

Learned Christian authors such as Basil of Caesarea, Ambrose and Augustine of Hippo were clearly aware of the sphericity of the Earth.

In constructing a map on any projection, a sphere is normally chosen to model the earth when the extent of the mapped region exceeds a few hundred kilometers in length in both dimensions.


Leo Ferrari
