Melancomas
Mela'ncomas
(Μελαγκόμας), an Ephesian, and NICO'MACHUS (Νικόμαχος), a Rhodian, were the two men whom Achaeus, the rebellious general of Antiochus the Great, employed to carry on his negotiations with Ptolemy IV. (Philopator), as well as all his other transactions with foreign powers. It was chiefly through recommendatory letters from Melancomas and Nicomachus that Bolis, of whose treachery they had no suspicion, was enabled to gain, to a great extent, the confidence of Achaeus, and so to betray him to Antiochus. in B. C. 214. (Plb. 8.17, 18, 20. 21.) [E.E]
