We do not know very much about Byzantine maps and Byzantine cartographic science in general. The material record is scant, many objects having been lost, destroyed, removed from their proper context (most often, to the West), or discarded when no longer useful, as is probably the case with Byzantine portolans between the second half of the 13th century and the Fall of Constantinople.

Nevertheless, there is a distinct possibility that more Byzantine manuscripts and specifically maps will be uncovered in libraries with significant historical collections, such as the Vatican Library, the Bodleian at Oxford, the National Library of Greece, and the Ataturk Library.
