Irenæus (Adv. Hær. III. 12. 8) says that this Eunuch returned to Ethiopia and preached there. But by no one else, so far as I know, is the origin of Christianity in Ethiopia traced back to him. The first certain knowledge we have of the introduction of Christianity into Ethiopia is in the fourth century, under Frumentius and Ædesius, of whom Rufinus, I. 9, gives the original account; and yet it is probable that Christianity existed there long before this time. Compare Neander’s Kirchengeschichte, I. p. 46. See also H. R. Reynolds’ article upon the “Ethiopian Church” in Smith and Wace’s Dictionary of Christian Biography, II. 232 sqq.
