Clement’s three principal works, the Exhortation to the Greeks (see below, note 5), the Instructor (note 6), and the Stromata, form a connected series of works, related to one another (as Schaff says) very much as apologetics, ethics, and dogmatics. The three works were composed in the order named. The Stromata (Στρωματεῖς) or Miscellanies (said by Eusebius in this passage to bear the title τῶν κατὰ τὴν ἀληθῆ φιλοσοφίαν γνωστικῶν ὑπομνημ€των στρωματεῖς) are said by Eusebius and by Photius (Cod. 109) to consist of eight books. Only seven are now extant, although there exists a fragment purporting to be a part of the eighth book, but which is in reality a portion of a treatise on logic, while in the time of Photius some reckoned the tract Quis dives salvetur as the eighth book (Photius, Cod. 111). There thus exists no uniform tradition as to the character of the lost book, and the suggestion of Westcott seems plausible, that at an early date the logical introduction to the Hypotyposes was separated from the remainder of the work, and added to some mss. of the Stromata as an eighth book. If this be true, the Stromata consisted originally of only seven books, and hence we now have the whole work (with the exception of a fragment lost at the beginning). The name Στρωματεῖς, “patchwork,” sufficiently indicates the character of the work. It is without methodical arrangement, containing a heterogeneous mixture of science, philosophy, poetry, and theology, and yet is animated by one idea throughout,—that Christianity satisfies the highest intellectual desires of man,—and hence the work is intended in some sense as a guide to the deeper knowledge of Christianity, the knowledge to be sought after by the “true Gnostic.” It is full of rich thoughts mingled with worthless crudities, and, like nearly all of Clement’s works, abounds in wide and varied learning, not always fully digested. The date at which the work was composed may be gathered from a passage in Bk. I. chap. 21, where a list of the Roman emperors is closed with a mention of Commodus, the exact length of whose reign is given, showing that he was already dead, but also showing apparently that his successor was still living. This would lead us to put the composition at least of the first book in the first quarter of the year 193. It might of course be said that Pertinax and Didius Julianus are omitted in this list because of the brevity of their reigns, and this is possible, since in his own list he gives the reigns of the emperors simply by years, omitting Otho and Vitellius. The other list which he quotes, however, gives every emperor, with the number of years, months, and even days of each reign, so that there is no reason, at least in that list, for the omission of Pertinax and Didius Julianus. It seems probable that, under the influence of that exact list, and of the recentness of the reigns of the two emperors named, Clement can hardly have omitted them if they had already ruled. We can say with absolute certainty, however, only that the work was written after 192. Clement left Alexandria in 202, or before, and this, as well as the rest of his works, was written in all probability before that time at the latest. The standard edition of Clement’s works is that of Potter, Oxford, 1715, in two vols. (reprinted in Migne’s Patr. Gr., Vols. VIII. and IX.). Complete English translation in the Ante-Nicene Fathers, Amer. ed., Vol. II. On his writings, see especially Westcott’s article in the Dict. of Christ. Biog. and for the literature on the subject Schaff’s Ch. Hist. II. 781.
