1911 Encyclopædia Britannica/Agathodaemon
AGATHODAEMON, of Alexandria, map designer, probably lived in the 2nd century A.D. Some MSS. of the Geography of Ptolemy contain twenty-seven maps, which are stated to have been drawn by Agathodaemon of Alexandria, who “delineated the whole world according to the eight books of Ptolemy's geography.” As Ptolemy speaks of Πίνακες to accompany his treatise, these maps were probably the work of a contemporary acting under his instructions. About 1470 Nicolaus Doris, a Benedictine monk, brought out a revised edition of them, the names being inserted in Latin instead of Greek.
