Passage 3.21.2
προϊόντι δὲ ὡς ἐπὶ τὴν Πελλάναν Χαράκωμά ἐστιν ὀνομαζόμενον καὶ μετὰ τοῦτο Πελλάνα πόλις τὸ ἀρχαῖον. Τυνδάρεων δὲ οἰκῆσαί φασιν ἐνταῦθα, ὅτε Ἱπποκόωντα καὶ τοὺς παῖδας ἔφευγεν ἐκ Σπάρτης. θέας δὲ ἄξια αὐτόθι ἰδὼν Ἀσκληπιοῦ τε οἶδα ἱερὸν καὶ τὴν πηγὴν Πελλανίδα. ἐς ταύτην λέγουσιν ὑδρευομένην ἐσπεσεῖν παρθένον, ἀφανισθείσης δὲ τὸ κάλυμμα ἀναφανῆναι τὸ ἐπὶ τῆς κεφαλῆς ἐν ἑτέρᾳ πηγῇ Λαγκίᾳ.
Proceeding towards Pellana, there is a place called Characoma, and after this lies Pellana, a city from ancient times. They say that Tyndareus lived here when he fled from Sparta because of Hippocoön and his sons. Among the notable sights that I know to be there are a sanctuary of Asclepius and the spring named Pellanis. They say that once a maiden, while drawing water, fell into this spring and disappeared; afterward, her veil was found appearing in another spring called Langia.
