Passage 5.16.4
ἐπανάγουσι δὲ καὶ τῶν παρθένων τὸν ἀγῶνα ἐς τὰ ἀρχαῖα, Ἱπποδάμειαν τῇ Ἤρᾳ τῶν γάμων τῶν Πέλοπος ἐκτίνουσαν χάριν τάς τε ἑκκαίδεκα ἀθροῖσαι γυναῖκας λέγοντες καὶ σὺν αὐταῖς διαθεῖναι πρώτην τὰ Ἡραῖα· μνημονεύουσι δὲ καὶ ὅτι Χλῶρις νικήσειεν Ἀμφίονος θυγάτηρ μόνη λειφθεῖσα τοῦ οἴκου. σὺν δὲ αὐτῇ καὶ ἕνα περιγενέσθαι φασὶ τῶν ἀρσένων· ἃ δὲ ἐς τοὺς Νιόβης παῖδας παρίστατο αὐτῷ μοι γινώσκειν, ἐν τοῖς ἔχουσιν ἐς Ἀργείους ἐδήλωσα.
They also trace the maidens' contest back to ancient times, saying that Hippodameia, to express her gratitude to Hera for her marriage to Pelops, gathered together sixteen women and with them first established the Heraea games. They also recall that Chloris, the daughter of Amphion, was victorious, the one woman alone who remained alive of her household. Along with her, they claim, a single male from the family also survived. Whatever I was able to discover about the children of Niobe, I have detailed in my account concerning the Argives.
