The Ptolemaic world map is a bold woodcut on the traditional modified conical projection with all regions above 65° north (just north of the British Isles) covered by the inscription Mare Congelatum or 'Frozen Sea'. The continents represented follow the Ptolemaic outline although the wood cutter has not felt he could sustain the concept of a land-locked Indian Ocean and so has omitted the strip of land normally linking southern Africa to Asia. The map itself is bordered by the ususal markings of latitude and longitude and the climates. Outside this is a vigorous surround of clouds with twelve characteristic windheads representing the classical winds blowing from each direction. (Shirley)
