Geographischer und astrologischer Zonenbegriff in der Antike

The five (or seven) zones are treated during Greek‐Roman antiquity in geography and theoretical astrology as well. Although there is no use of them in astrological prognostication, they occur in the ascending scale of the twelve planetary houses. The common planetary order (moon ‐ Mercury ‐Venus ‐ sun ‐ Mars ‐ Jupiter ‐ Saturn) owes its widespread success primarily to its symmetry on both sides of the central sun, but the twofold vertical mesotes‐pattern in the heaven seems to be invented according to the horizontal symmetry of the five geographical zones surrounding the terrestrial equator.
