(Κνωπίας), of Alorus, an officer who, having seen some active service under Demetrius II. and Antigonus Doson, was one of those employed by Agathocles and Sosibius, ministers of Ptolemy IV. (Philopator) to superintend the provision of arms and the choice and training of the troops when Egypt was threatened with war by Antiochus the Great in B. C. 219. Cnopias is said by Polybius to have performed the duty entrusted to him with ability and zeal. (5.63-65.)
