Theophilus of Antioch, To Autolycus 30
Cain also fathered a son named Enoch, and he built a city which he named after his son Enoch (Genesis 4:17). From that point onward the building of cities began, and this occurred before the flood; not as Homer falsely says, 'For not yet had a city been built for mortal men.'
To Enoch was born a son named Gaidad; Gaidad fathered Meel, Meel fathered Mathusala, and Mathusala fathered Lamech. Lamech took two wives, Ada and Sella, and from that time the practice of bigamy and the origin of music began. Lamech had three sons: Obel, Jubal, and Tubel. Obel became a man who lived in tents and raised livestock; Jubal was the one who introduced the psaltery and the harp; and Tubel became a metalworker, forging copper and iron.
Thus the line of Cain had a recorded catalog up to this point, but afterward his genealogy fell into oblivion because he had murdered his brother. In place of Abel, God gave Eve to conceive and bear a son named Seth, from whom the rest of humanity descends to this day. For anyone who wishes and loves to learn, it is easy to demonstrate every generation through the holy scriptures. A partial account has already been given in another work, as we noted above, outlining the genealogy in the first book of histories. The Holy Spirit teaches us all these things through Moses and the other prophets, so that our sacred writings are shown to be more ancient and also more true than those of any other writers and poets.
Some have foolishly claimed that Apollo invented music, while others say Orpheus discovered it from the sweet song of birds. Their claims are empty and vain, for these figures lived many years after the flood.
The account of Noah, who is also called Deucalion by some, has been presented in the book mentioned earlier; if you wish, you may examine it as well.
Greek
Ὁ οὖν Κάϊν καὶ αὐτὸς ἔσχεν υἱόν, ᾧ ὄνομα Ἐνώχ. Καὶ ᾠκοδόμησεν πόλιν, ἣν ἐπωνόμασεν ἐπὶ τῷ ὀνόματι τοῦ υἱοῦ αὐτοῦ Ἐνώχ. Ἀπὸ τότε ἀρχὴ ἐγένετο τοῦ οἰκοδομεῖσθαι πόλεις, καὶ τοῦτο πρὸ κατακλυσμοῦ· οὐχ ὡς Ὅμηρος ψεύδεται λέγων· Οὐ γάρ πω πεπόλιστο πόλις μερόπων ἀνθρώπων. Τῷ δὲ Ἐνὼχ ἐγενήθη υἱὸς ὀνόματι Γαϊδάδ· ἐγέννησεν τὸν καλούμενον Μεήλ, καὶ Μεὴλ τὸν Μαθουσάλα, καὶ Μαθουσάλα τὸν Λάμεχ. Ὁ δὲ Λάμεχ ἔλαβεν ἑαυτῷ δύο γυναῖκας, αἷς ὀνόματα Ἀδᾶ καὶ Σελᾶ. Ἔκτοτε ἀρχὴ ἐγένετο τῆς πολυμιξίας, ἀλλὰ καὶ τῆς μουσικῆς. Τῷ γὰρ Λάμεχ ἐγένοντο τρεῖς υἱοί, Ὠβὴλ Ἰουβὰλ Θοβέλ. Καὶ ὁ μὲν Ὠβὴλ ἐγένετο ἀνὴρ ἐν σκηναῖς κτηνοτροφῶν, Ἰουβὰλ δέ ἐστιν ὁ καταδείξας ψαλτήριον καὶ κιθάραν, Θοβὲλ δὲ ἐγένετο σφυροκόπος χαλκεὺς χαλκοῦ καὶ σιδήρου. Ἕως μὲν οὖν τούτου ἔσχεν τὸν κατάλογον τὸ σπέρμα τοῦ Κάϊν· καὶ τὸ λοιπὸν εἰς λήθην αὐτοῦ γέγονεν τὸ σπέρμα τῆς γενεαλογίας, διὰ τὸ ἀδελφοκτονῆσαι αὐτὸν τὸν ἀδελφόν. Εἰς τὸν τόπον δὲ τοῦ Ἄβελ ἔδωκεν ὁ θεὸς συλλαβεῖν τὴν Εὔαν καὶ τεκεῖν υἱὸν, ὃς κέκληται Σήθ· ἀφ᾿ οὗ τὸ λοιπὸν γένος τῶν ἀνθρώπων ὁδεύει μέχρι τοῦ δεῦρο. Τοῖς δὲ βουλομένοις καὶ φιλομαθέσιν καὶ περὶ πασῶν τῶν γενεῶν εὔκολόν ἐστιν ἐπιδεῖξαι διὰ τῶν ἁγίων γραφῶν. Καὶ γὰρ ἐκ μέρους ἡμῖν γεγένηται ἤδη λόγος ἐν ἑτέρῳ λόγῳ, ὡς ἐπάνω προειρήκαμεν, τῆς γενεαλογίας ἡ τάξις ἐν τῇ πρώτῃ βίβλῳ τῇ περὶ ἱστοριῶν. Ταῦτα δὲ πάντα ἡμᾶς διδάσκει τὸ πνεῦμα τὸ ἅγιον, τὸ διὰ Μωσέως καὶ τῶν λοιπῶν προφητῶν, ὥστε τὰ καθ᾿ ἡμᾶς τοὺς θεοσεβεῖς ἀρχαιότερα γράμματα τυγχάνει, οὐ μὴν ἀλλὰ καὶ ἀληθέστερα πάντων συγγραφέων καὶ ποιητῶν δείκνυται ὄντα.Ἀλλὰ μὴν καὶ τὰ περὶ τῆς μουσικῆς ἐφλυάρησάν τινες εὑρετὴν Ἀπόλλωνα γεγενῆσθαι· ἄλλοι δὲ Ὄρφεα ἀπὸ τῆς τῶν ὀρνέων ἡδυφωνίας φασὶν ἐξευρηκέναι τὴν μουσικήν. Κενὸς δὲ καὶ μάταιος ὁ λόγος αὐτῶν δείκνυται· μετὰ γὰρ πολλὰ ἔτη τοῦ κατακλυσμοῦ οὗτοι ἐγένοντο. Τὰ δὲ περὶ τοῦ Νῶε, ὅς κέκληται ὑπὸ ἐνίων Δευκαλίων, ἐν τῇ βίβλῳ ᾗ προειρήκαμεν ἡ διήγησις ἡμῖν γεγένηται· ᾗ, εἰ βούλει, καὶ σὺ δύνασαι ἐντυχεῖν.
