I read μετὰ τοῦτον with the majority of the mss., with Burton, Routh, Schwegler, Heinichen, &c., instead of μετὰ τοῦτο, which occurs in some mss. and in Rufinus, and is adopted by Valesius, Crusè, and others. As Burton says, the copyists of Eusebius, not knowing to whom Proclus here referred, changed τοῦτον to τοῦτο; but if we had the preceding context we should find that Proclus had been referring to some prophetic man such as the Montanists were fond of appealing to in support of their position. Schwegler suggests that it may have been the Quadratus mentioned in chap. 37, but this is a mere guess. As the sentence stands isolated from its connection, τοῦτον is the harder reading, and could therefore have more easily been changed into τοῦτο than the latter into τοῦτον.
