This Quadratus had considerable reputation as a prophet, as may be gathered from Eusebius’ mention of him here, and also from the reference to him in the anonymous work against the Montanists (see below, Bk. V. chap. 16). We know nothing about this Quadratus except what is told us in these two passages, unless we identify him, as many do, with Quadratus the apologist mentioned below, in Bk. IV. chap. 3. This identification is possible, but by no means certain. See Bk. IV. chap. 3, note 2.
