F. J. (Frederick John) Church translation
Ptolemy, the mediæval authority on geography, divided the known world into κλίματα, zones of slope towards the pole, or belts of latitude, eight of which from the equinoctial to the mouths of the Tanais and the Riphæan mountains. The seventh "clima" passed over the mouths of the Borysthenes. See Mercator's map in Bertius' Theatrum Geographiæ Veteris (1618), art. "Ptolemy" in Smith's Dictionary of Biography, p. 577.
