Miltiaides an early ecclesiastical writer, noted for his able defence of the orthodox Church against the Montanists, is supposed to have flourished towards the close of the 2d century. Eusebius and Jerome mention his writings, but there is now no trace of these supposed valuable productions. He is said to have lived under Marcus Aurelius (161-180), and under his son and successor Commodus (180-192). Miltiades was an able polemic, and waged war successfully, not only against the Montanists, but also combated Judaism and heathenism in its various phases. See Eusebius, Hist. Eccles. 5:17.
