§4.104.1Ἀγάθυρσοι δὲ ἁβρότατοι ἀνδρῶν εἰσι καὶ χρυσοφόροι τὰ μάλιστα, ἐπίκοινον δὲ τῶν γυναικῶν τὴν μῖξιν ποιεῦνται, ἵνα κασίγνητοι τε ἀλλήλων ἔωσι καὶ οἰκήιοι ἐόντες πάντες μήτε φθόνῳ μήτε ἔχθεϊ χρέωνται ἐς ἀλλήλους.
The Agathyrsi are the most luxurious of men and wear gold to the highest degree; and they make their intercourse with women common to all, so that they may be brothers to one another and, being all kinsmen, may feel neither envy nor malice toward one another.
τὰ δὲ ἄλλα νόμαια Θρήιξι προσκεχωρήκασι.
In their other customs they have come close to the Thracians.
