Plutarch, De Iside et Osiride 49

μεμιγμένη γὰρ ἡ τοῦδε τοῦ κόσμου γένεσις καὶ σύστασις ἐξ ἐναντίων, οὐ μὴν ἰσοσθενῶν, δυνάμεων, ἀλλὰ τῆς βελτίονος τὸ κράτος ἐστίν· ἀπολέσθαι δὲ τὴν φαύλην παντάπασιν ἀδύνατον, πολλὴν μὲν ἐμπεφυκυῖαν τῷ σώματι, πολλὴν δὲ τῇ ψυχῇ τοῦ παντὸς καὶ πρὸς τὴν βελτίονα ἀεὶ δυσμαχοῦσαν. ἐν μὲν οὖν τῇ ψυχῇ νοῦς καὶ λόγος ὁ τῶν ἀρίστων πάντων ἡγεμὼν καὶ κύριος Ὄσιρίς ἐστιν· ἐν δὲ γῇ καὶ πνεύματι καὶ ὕδατι καὶ οὐρανῷ καὶ ἄστροις τὸ τεταγμένον καὶ καθεστηκὸς καὶ ὑγιαῖνον, ὥραις καὶ κράσεσι καὶ περιόδοις Ὀσίριδος ἀπορροὴ καὶ εἰκὼν ἐμφαινομένη· Τυφὼν δὲ τῆς ψυχῆς τὸ παθητικὸν καὶ τιτανικὸν καὶ ἄλογον καὶ ἔμπληκτον τοῦ δὲ σωματικοῦ τὸ ἐπίκηρον καὶ νοσῶδες καὶ ταρακτικὸν ἀωρίαις καὶ δυσκρασίαις, καὶ κρύψεσιν ἡλίου καὶ ἀφανισμοῖς σελήνης, οἷον ἐκδρομαὶ καὶ ἀφανισμοὶ Τυφῶνος· καὶ τοὔνομα κατηγορεῖ τὸ Σήθ, ᾧ τὸν Τυφῶνα καλοῦσι· φράζει μὲν γὰρ τὸ καταδυναστεῦον καὶ καταβιαζόμενον, φράζει δὲ τὴν πολλάκις ἀναστροφὴν καὶ πάλιν ὑπερπήδησιν. Βέβωνα δὲ τινὲς μὲν ἕνα τῶν τοῦ Τυφῶνος ἑταίρων γεγονέναι λέγουσιν, Μανεθὼς δʼ αὐτὸν τὸν Τυφῶνα καὶ Βέβωνα καλεῖσθαι· σημαίνει δὲ τοὔνομα κάθεξιν ἢ κώλυσιν, ὡς τοῖς πράγμασιν ὁδῷ βαδίζουσι καὶ πρὸς ὃ χρὴ φερομένοις ἐνισταμένης τῆς τοῦ Τυφῶνος δυνάμεως

The fact is that the creation and constitution of this world is complex, resulting, as it does, from opposing influences, which, however, are not of equal strength, but the predominance rests with the better. Yet it is impossible for the bad to be completely eradicated, since it is innate, in large amount, in the body and likewise in the soul of the Universe, and is always fighting a hard fight against the better. So in the soul Intelligence and Reason, the Ruler and Lord of all that is good, is Osiris, and in earth and wind and water and the heavens and stars that which is ordered, established, and healthy, as evidenced by seasons, temperatures, and cycles of revolution, is the efflux of Osiris and his reflected image. But Typhon is that part of the soul which is impressionable, impulsive, irrational and truculent, and of the bodily part the destructible, diseased and disorderly as evidenced by abnormal seasons and temperatures, and by obscurations of the sun and disappearances of the moon, outbursts, as it were, and unruly actions on the part of Typhon. And the name Seth, by which they call Typhon, denotes this; it means the overmastering and overpowering, and it means in very many instances turning back, and again overpassing. Some say that one of the companions of Typhon was Bebon, but Manetho says that Bebon was still another name by which Typhon was called. The name signifies restraint or hindrance, as much as to say that, when things are going along in a proper way and making rapid progress towards the right end, the power of Typhon obstructs them.
