We know nothing of Rhodo except what is contained in this chapter. Jerome gives a very brief account of him in his de vir. ill. 37, but it rests solely upon this chapter, with the single addition of the statement that Rhodo wrote a work Against the Phrygians. It is plain enough, however, that he had for his account no independent source, and that he in this statement simply attributed to Rhodo the work quoted by Eusebius as an anonymous work in chap. 16. Jerome permits himself such unwarranted combinations very frequently, and we need not be at all surprised at it. With him a guess is often as good as knowledge, and in this case he doubtless considered his guess a very shrewd one. There is no warrant for supposing that he himself saw the work mentioned by Eusebius, and thus learned its authorship. What Eusebius did not learn from it he certainly could not, and his whole account betrays the most slavish and complete dependence upon Eusebius as his only source. In chap. 39 Jerome mentions Rhodo again as referring, in a book which he wrote against Montanus, Prisca, and Maximilla, to Miltiades, who also wrote against the same heretics. This report is plainly enough taken directly from Eusebius, chap. 17, where Eusebius quotes from the same anonymous work. Jerome’s utterly baseless combination is very interesting, and significant of his general method. Rhodo’s works are no longer extant, and the only fragments we have are those preserved by Eusebius in this chapter.
