Conventional name for a manuscript made at Colmar c.1200 of a late Roman world‐map, itself a 4th‐cent. modification of a 2nd‐cent. and perhaps even earlier design. The most valuable document of ancient cartography (see maps), it is also an important source for ancient topography. It represents the inhabited world from Spain and Britain (all but a fragment of which are missing) to India, though the Mediterranean world occupies five‐sixths of the whole (and Italy a third) of the scroll. The elongated form precludes constant scale or recognizable visual form for most land‐masses and seas; but the dense and topologically correct network of roads (with posting‐stations and distances) has a practical value. Major cities have pictorial images, middle‐ranking ones conventional signs. Important rivers, mountains, and some other features of historical significance are included.
