Φέρε οὖν, ὅπως ἂν οἷοί τε ὦμεν, ὑμνήσωμεν αὐτοῦ τὴν ἑορτήν, ἣν ἡ βασιλεύουσα πόλις ἐπετησίοις ἀγάλλει θυσίαις. ἔστι μὲν οὖν, εὖ οἶδα, χαλεπὸν καὶ τὸ ξυνεῖναι περὶ αὐτοῦ μόνον, ὁπόσος τίς ἐστιν ὁ ἀφανὴς [132] ἐκ τοῦ φανεροῦ λογισαμένῳ, φράσαι δὲ ἴσως ἀδύνατον, εἰ καὶ τῆς ἀξίας ἔλαττον ἐθελήσειέ τις. ἐφικέσθαι μὲν γὰρ τοῦ πρὸς ἀξίαν εὖ οἶδα ὅτι τῶν ἁπάντων οὐδεὶς ἂν δύναιτο, τοῦ μετρίου δὲ μὴ διαμαρτεῖν ἐν τοῖς ἐπαίνοις τὸ κεφάλαιόν ἐστι τῆς ἀνθρωπίνης ἐν τῷ δύνασθαι φράζειν δυνάμεως. ἀλλ᾽ ἔμοιγε τούτου παρασταίη βοηθὸς ὅ τε λόγιος(624) Ἑρμῆς ξὺν ταῖς Μούσαις ὅ τε Μουσηγέτης Ἀπόλλων,(625) [B] ἐπεὶ καὶ αὐτῷ προσήκει τῶν λόγων, καὶ δοῖεν δὲ εἰπεῖν ὁπόσα τοῖς θεοῖς φίλα λέγεσθαί τε καὶ πιστεύεσθαι περὶ αὐτῶν. τίς οὖν ὁ τρόπος ἔσται τῶν ἐπαίνων; ἢ δῆλον ὅτι περὶ τῆς οὐσίας αὐτοῦ καὶ ὅθεν προῆλθε καὶ τῶν δυνάμεων καὶ τῶν ἐνεργειῶν διελθόντες, ὁπόσαι φανεραὶ ὅσαι τ᾽ ἀφανεῖς, καὶ περὶ τῆς τῶν ἀγαθῶν δόσεως, ἣν κατὰ πάντας ποιεῖται τοὺς κόσμους, οὐ παντάπασιν ἀπᾴδοντα ποιησόμεθα τῷ θεῷ τὰ ἐγκώμια; [C] ἀρκτέον δὲ ἐνθένδε. (Come then, let me celebrate, as best I may, his festival which the Imperial city(626) adorns with annual sacrifices.(627) Now it is hard, as I well know, merely to comprehend how great is the Invisible, if one judge by his visible self,(628) and to tell it is perhaps impossible, even though one should consent to fall short of what is his due. For well I know that no one in the world could attain to a description that would be worthy of him, and not to fail of a certain measure of success in his praises is the greatest height to which human beings can attain in the power of utterance. But as for me, may Hermes, the god of eloquence, stand by my side to aid me, and the Muses also and Apollo, the leader of the Muses, since he too has oratory for his province, and may they grant that I utter only what the gods approve that men should say and believe about them. What, then, shall be the manner of my praise? Or is it not evident that if I describe his substance and his origin, and his powers and energies, both visible and invisible, and the gift of blessings which he bestows throughout all the worlds,(629) I shall compose an encomium not wholly displeasing to the god? With these, then, let me begin.)
