Eunapius, Live of the Philosophers 2.2.4
“Even though I have recorded these things faithfully, I do recognize that some things have probably escaped me. And if, although I have applied great thought and effort trying to compose a continuous and clear history of the lives of the best philosophers and rhetoricians, I did not obtain my goal, I have suffered much the same kind of thing as those who love madly and obsessively. For they, when they see the one they love and witness her overwhelming beauty in real life, they look down, too weak and dazed to gaze upon the one they desire.”
Καὶ ταῦτά γε εἰς μνήμην ἐγὼ τίθεμαι, τοῦτο συνορῶν, ὅτι τὰ μὲν ἔλαθεν ἴσως ἡμᾶς, τὰ δὲ οὐκ ἔλαθεν. ἐκείνου δὲ καίπερ πολλὴν ποιούμενος φροντίδα καὶ σπουδήν, τοῦ συνεχῆ καὶ περιγεγραμμένην εἰς ἀκρίβειαν ἱστορίαν τινὰ λαβεῖν τοῦ φιλοσόφου καὶ ῥητορικοῦ βίου τῶν ἀρίστων ἀνδρῶν, εἶτα οὐ τυγχάνων τῆς ἐπιθυμίας, ταὐτόν τι τοῖς ἐρῶσιν ἐμμανῶς καὶ περιφλέκτως ἔπαθον. καὶ γὰρ ἐκεῖνοι, τὴν μὲν ἐρωμένην αὐτὴν ὁρῶντες καὶ τὸ περίψυκτον ἐν τῷ φαινομένῳ κάλλος, κάτω νεύουσιν, ὃ ζητοῦσιν ἰδεῖν ἐξασθενοῦντες, καὶ περιλαμπόμενοι•
