Clement of Alexandria I: Protrepticus and Paedagogus

[...Clement] was known, who shared the name with the one who led the church of the Romans long ago, a student of the apostles. He himself mentions Pantaenus as his teacher by name in the Hypotyposes which he compiled (cf. Zahn, op. cit. p. 65), and it seems to me that he hints at this same person in the first book of the Stromata, when he identifies the most prominent figures of the apostolic succession he has encountered, saying the same:
(follows Stromata I 11). H. E. III 23, 2: "It is sufficient to confirm the account by two witnesses, and these would be faithful who have served the ecclesiastical orthodoxy, if indeed Irenaeus and Clement of Alexandria are such." IV 26, 4: "Clement of Alexandria mentions this discourse" (Melito’s book on Easter) "in his own discourse on the Passover, which he says he compiled due to the occasion of Melito’s writing."
VI 6: "Clement succeeded Pantaenus1 as head of the catechetical school in Alexandria, holding the position up to that time, so that Origen became one of his students. Clement, in his commentary on the Stromata, laying out a chronological record in his first book, limits the times to the death of Commodus, so it is clear that his studies were carried out under Severus, whose times the present history reports." VI 13, 14: "All eight of Clement’s Stromata are preserved by us, which he also deemed worthy of such a title: 'Titus Flavius Clement’s Miscellanies of Gnostic Notes according to the True Philosophy.'"
"Equal in number to these are his books titled Hypotyposes, in which he mentions Pantaenus by name as his teacher, and writes down his teachings and expositions. He also has a discourse to the Greeks, the Protrepticus, and the three books of the so-called Paedagogus, and Who is the Rich Man Being Saved?, another of his discourses so titled; as well as the work On the Passover, and Lectures on Fasting and On Slander, and the Exhortation to Patience or To the Newly Baptized, and the work entitled Ecclesiastical Canon or Against the Judaizers, which he dedicated to the aforementioned Bishop Alexander."
"In the Stromata he has made a compilation not only of the divine scripture but also of the writings of the Greeks, if anything seemed useful to have been said by them, and he mentions the opinions held by the majority, unfolding both the Greeks' and the barbarians' views, and furthermore correcting the false doctrines of the heresiarchs, spreading out much history and providing us with a subject of deep, learned education. To all these he mixes in the doctrines of the philosophers."
