Treats rough and smooth breathing on rho and vowels: examples (Ῥαρίδος, Ῥαρία, Ῥαριάς, Ῥάριον), rule for double rho in middle of word (first smooth, second rough), initial breathing always shown, medial rarely, and assimilation where a preceding smooth becomes rough before a following rough-initial vowel; notes Aeolic dialect exception.
«᾿Ραρίδος Δηοῦς» καὶ ᾿Ραρία γῆ καὶ ᾿Ραριάς, σημαίνει δὲ τὴν Δήμητρα, καὶ ᾿Ράριον πεδίον ἐν Ἐλευσῖνι, ἐπὶ τούτων γάρ φασι τὸ μὲν πρῶτον 'ρ' ψιλοῦσθαι, τὸ δὲ δεύτερον δασύνεσθαι. ἀλλὰ τὰ δύο 'ρρ' ψιλωτέον ἐπὶ τούτων καὶ κατὰ τὴν πρώτην συλλαβὴν καὶ κατὰ τὴν δευτέραν. Τὸ 'ρ', ἐὰν δισσὸν γένηται ἐν μέσῃ λέξει, τὸ μὲν πρῶτον ψιλοῦται, τὸ δὲ δεύτερον δασύνεται οἷον συῤῥάπτω. * Τὸ πνεῦμα κατὰ τὴν ἀρχὴν ἀεὶ φαίνεται, καὶ μέσον ὀλιγάκις. * Ἐπὶ τῶν σχετλιαστικῶν ἔσθ´ ὅτε τὸ δασὺ πνεῦμα ἀλόγως ἐν τῇ ληγούσῃ συλλαβῇ ὁρᾶται, ὡς ἔχει τὸ εὐοἵ, εὔἁν, εὐαἵ. * Δασυνομένου φωνήεντος ἐπιφερομένου τὸ προηγούμενον ψιλὸν τρέπεται εἰς τὸ ἀντίστοιχον δασύ, κατὰ ἡμῶν καθ´ ἡμῶν. τὸ δὲ ἀνάπαλιν οὔ, εἰ μὴ κατὰ διάλεκτον τραπῇ. τὸ γὰρ ἀμπέχεσθαι Αἰολικόν ἐστιν.
“᾿Ραρίδος Δηοῦς” and ᾿Ραρία γῆ and ᾿Ραριάς: it signifies Demeter, and the ᾿Ράριον plain in Eleusis; for in these cases, they say that the first ρ is to be pronounced with smooth breathing, but the second with rough breathing. But in these cases the two ρρ must be given smooth breathing, both in the first syllable and in the second. The letter ρ, if it becomes double in the middle of a word, the first is given smooth breathing and the second rough breathing, as in συῤῥάπτω. The breathing at the beginning is always evident, and in the middle only rarely. In exclamatory expressions it sometimes happens that the rough breathing is seen irrationally on the final syllable, as in εὐοἵ, εὔἁν, εὐαἵ. When a vowel with rough breathing follows, the preceding smooth is changed into the corresponding rough, as in καθ᾿ ἡμῶν for κατ᾿ ἡμῶν. But the reverse does not occur, unless it is changed according to dialect; for ἀμπέχεσθαι is Aeolic.
