Of this cynic philosopher Crescens we know only what is told us by Justin and Tatian, and they paint his character in the blackest colors. Doubtless there was sufficient ground for their accusations; but we must remember that we have his portrait only from the pen of his bitterest enemies. In the Acta Crescens is not mentioned in connection with the death of Justin,—an omission which is hardly to be explained, except upon the supposition of historical truthfulness. Eusebius’ report here seems to rest solely upon the testimony of Tatian (see §§8 and 9, below), but the passage of Tatian which he cites does not prove his point; it simply proves that Crescens plotted against Justin; whether his plotting was successful is not stated, and the contrary seems rather to be implied (see note 13, below).
