Of this Asterius Urbanus we know only what we can gather from this reference to him. Valesius, Tillemont, and others supposed that the words ἐν τῷ αὐτῷ λόγῳ τῷ κατὰ ᾽Αστέριον Οὐρβανόν were a scholium written on the margin of his copy by Eusebius himself or some ancient commentator to indicate the authorship of the anonymous work from which the fragments in this chapter are taken (and so in the Ante-Nicene Fathers, Vol. VII., these fragments are given as from the work of Asterius Urbanus). But Eusebius himself evidently did not know the author, and it is at any rate much easier to suppose the words a part of the text, and the work of Asterius a work which our anonymous author has been discussing and from which he quotes the words of Maximilla, just below. Accepting this most natural interpretation of the words, we learn that Asterius Urbanus was a Montanist who had written a work in defense of that sect.
