On the life of Clement, see Bk. V. chap. 11, note 1. He was a very prolific writer, as we can gather from the list of works mentioned in this chapter. The list is repeated by Jerome (de vir. ill. c. 38) and by Photius (Cod. 109–111), the former of whom merely copies from Eusebius, with some mistakes, while the latter copies from Jerome, as is clear from the similar variations in the titles given by the last two from those given by Eusebius, and also by the omission in both their lists of one work named by Eusebius (see below, note 10). Eusebius names ten works in this chapter. In addition to these there are extant two quotations from a work of Clement entitled περὶ προνοίας. There are also extant two fragments of a work περί ψυχῆς. In the Instructor, Bk. II. chap. 10, Clement refers to a work On Continence (ὁ περὶ ἐγκρατείας) as already written by himself, and there is no reason to doubt that this was a separate work, for the third book of the Stromata (to which Fabricius thinks he refers), which treats of the same subject, was not yet written. The work is no longer extant. In the Instructor, Bk. III. chap. 8, Clement speaks of a work which he had written On Marriage (ὁ γαμικὸς λόγος). It has been thought possible that he may have referred here to his discussion of the same subject in Bk. II. chap. 10 of the same work (see the Bishop of Lincoln’s work on Clement, p. 7), but it seems more probable that he referred to a separate work now lost. Potter, p. 1022, gives a fragment which is possibly from this work. In addition to these works, referred to as already written, Clement promises to write on First Principles (περὶ ἀρχῶν; Strom. III. 3, IV. 1, 13, V. 14, et al.); on Prophecy (Strom. I. 24, IV. 13, V. 13); on Angels (Strom. VI. 13); on the Origin of the World (Strom. VI. 18),—perhaps a part of the proposed work on First Principles, and perhaps to be identified with the commentary on Genesis, referred to below by Eusebius (see note 28),—Against Heresies (Strom. IV. 13), on the Resurrection (Instructor, I. 6, II. 10). It is quite possible that Clement regarded his promises as fulfilled by the discussions which he gives in various parts of the Stromata themselves, or that he gave up his original purpose.
