Εὐθὺς μὲν οὖν ἐννοήσας τις τὰ γιγνόμενα ἡγήσατ’ ἂν φύσει βασιλικόν τι κάλλος εἶναι, ἄλλως τε καὶ ἂν μετ’ αἰδοῦς καὶ σωφροσύνης, καθάπερ Αὐτόλυκος τότε, κεκτῆταί τις αὐτό. πρῶτον μὲν γάρ, ὥσπερ ὅταν φέγγος τι ἐν νυκτὶ φανῇ, πάντων προσάγεται τὰ ὄμματα, οὕτω καὶ τότε τοῦ Αὐτολύκου τὸ κάλλος πάντων εἷλκε τὰς ὄψεις πρὸς αὐτόν· ἔπειτα τῶν ὁρώντων οὐδεὶς οὐκ ἔπασχέ τι τὴν ψυχὴν ὑπ’ ἐκείνου. οἱ μέν γε σιωπηρότεροι ἐγίγνοντο, οἱ δὲ καὶ ἐσχηματίζοντό πως. πάντες μὲν οὖν οἱ ἐκ θεῶν του κατεχόμενοι ἀξιοθέατοι δοκοῦσιν εἶναι· ἀλλ’ οἱ μὲν ἐξ ἄλλων πρὸς τὸ γοργότεροί τε ὁρᾶσθαι καὶ φοβερώτερον φθέγγεσθαι καὶ σφοδρότεροι εἶναι φέρονται, οἱ δ’ ὑπὸ τοῦ σώφρονος ἔρωτος ἔνθεοι τά τε ὄμματα φιλοφρονεστέρως ἔχουσι καὶ τὴν φωνὴν πρᾳοτέραν ποιοῦνται καὶ τὰ σχήματα εἰς τὸ ἐλευθεριώτερον ἄγουσιν. ἃ δὴ καὶ Καλλίας τότε διὰ τὸν ἔρωτα πράττων ἀξιοθέατος ἦν τοῖς τετελεσμένοις τούτῳ τῷ θεῷ.
(Xenophon, Symp. 1.8-10)
A person who took note of what happened would have come at once to the conclusion that beauty is something naturally regal, especially when, as in the present case of Autolycus, its possessor joins with it modesty and self-control. For in the first place, just as the sudden glow of a light at night draws all eyes to itself, so now the beauty of Autolycus compelled everyone to look at him. And second, there was not one of the onlookers who did not feel his soul stirred by the boy; some of them grew quieter than before, others even assumed some kind of a pose. Now it is true that all who are possessed by any kind of the gods seem well worth gazing at; but whereas in the case of other gods they have a tendency to look bugeyed, making terrifying sounds, and behave more vehemently, those who are inspired by chaste Eros have a more affectionate look, make their voices more gentle, and carry themselves in a way most befitting free men. Such was the demeanor of Callias at this time under the influence of Eros; and therefore he was an object well worth the gaze of those initiated into the worship of this god. (tr.
