As a breeze or an echo rebounds from the smooth rocks and returns whence it came, so does the stream of beauty, passing through the eyes which are the windows of the soul, come back to the beautiful one.
οἷον πνεῦμα ἤ τις ἠχὼ ἀπὸ λείων τε καὶ στερεῶν ἁλλομένη πάλιν ὅθεν ὡρμήθη φέρεται, οὕτω τὸ τοῦ κάλλους ῥεῦμα πάλιν εἰς τὸν καλὸν διὰ τῶν ὀμμάτων ἰόν
