Note 107 — PHOTIUS BIBLIOTHECA OR MYRIOBIBLON[6]
John Henry Freese translation
Before the earth was regarded as spherical, its surface was supposed to “slope” (κλίνω) from S. to N., and this slope was called κλίμα. Later, the word was used for belts or zones of its surface, and then for the temperature of those zones. According to Cosmas, the two “climates” were between the latitudes of Alexandria and Rhodes, and Rhodes and Constantinople (about 635 miles).
