Hermas - (Easton's Bible Dictionary)
Mercury, a Roman Christian to whom Paul sends greetings (Rom. 16: 14). Some suppose him to have been the author of the celebrated religious romance called The Shepherd, but it is very probable that that work is the production of a later generation.

hur'-mas (Hermas): An abbreviated form of several names, e.g. Hermagoras, Hermeros, Hermodorus, Hermogenes, etc.; the name of a Roman Christian to whom Paul sent greetings (Ro 16:14). Origen and some later writers have identified him with the author of The Pastor of Hermas, but without sufficient reason. According to the Canon of Muratori, the author of The Pastor wrote when his brother Pius was bishop of Rome (140-55 AD). He speaks of himself, however, as a contemporary of Clement of Rome (chapter 4) (circa 100 AD). The name Hermas is very common, and Origen's identification is purely conjectural.
