6.6.1
VI. Πάνταινον δὲ Κλήμης διαδεξάμενος, τῆς κατ’ Ἀλεξάνδρειαν κατηχήσεως εἰς ἐκεῖνο τοῦ καιροῦ καθηγεῖτο, ὡς καὶ τὸν Ὠριγένην τῶν φοιτητῶν γενέαθαι αὐτοῦ. τήν γέ τοι τῶν Στρωματέων πραγματείαν ὁ Κλήμης ὑπομνηματιζόμενος, κατὰ τὸ πρῶτον σύγγραμμα χρονικὴν ἐκθέμενος γραφήν, εἰς τὴν Κομόδου τελευτὴν περιγράφει τοὺς χρόνους, ὡς εἶναι σαφὲς ὅτι κατὰ Σευῆρον αὐτῷ πεπόνητο τὰ σπουδάσματα, οὗ τοὺς χρόνους ὁ παρὼν ἱστορεῖ λόγος.
VI. Pantaenus was succeeded by Clement, who directed the instruction at Alexandria at this time, so that Origen also was one of his pupils. In fact Clement, when compiling his Stromateis, in the first book displays a chronological table, using the death of Commodus as a terminus in measuring his dates; so that it is clear that the work was composed by him under Severus, whose time this present account is describing.
