From Rome to the Antipodes: the medieval form of the world
  Here we discuss how some medieval scholars in the Western Europe viewed the form of the world and the problem of the Antipodes, starting from the Natural History written by Pliny and ending in the Hell of Dante Alighieri. From the center of the Earth, Dante and Virgil came to the Antipodes: eventually, their existence was accepted. Among the others, we will discuss the works of the Venerable Bede and Sylvester the Second.
