Though he never actually crossed it, the Greek mathematician Pythagoras is sometimes credited with having first conceived of the Equator, calculating its location on the Earth’s sphere more than four centuries before the birth of Christ. Aristotle, who never stepped over it either and knew nothing about the landscape surrounding it, pictured the equatorial region as a land so hot that no one could survive there: the ‘Torrid Zone’. For the Greeks, the inhabited world to the north — what they called the oikumene — existed opposite an uncharted region called the antipodes. The two areas were cut off from one another by the Equator, an imaginary line often depicted as a ring of fire populated by mythical creatures. (via Kurt Hollander - The Equator)
