Zonal map, thirteenth-century. Size of the original: square frame, 18.5 x 18.5 cm (7 1/4" x 7 1/4"); diameter of circular world, 17 cm (6 3/4") The map,
which illustrates a manuscript of the Etymologies by Isidore of Seville, shows the earth divided into five zones: frigid zones in the north (right) and south
(left); two temperate zones--the southern one being unknown, the northern one containing the three known continents; and a central perusta zona, separat-
ing the habitable zones with its heat and ocean. At the map's corners are four classical deities associated with the sea: Triton, Neptune, Thetis, and Aeolus.
