Passage 6.25.4
τοῖς δὲ Ἠλείοις καὶ Τύχης ἐστὶν τὸ ἱερὸν· ἐν στοᾷ δὲ τοῦ ἱεροῦ μεγέθει μέγα ἄγαλμα ἀνάκειται, ξόανον ἐπίχρυσον πλὴν προσώπου καὶ χειρῶν τε ἄκρων καὶ ποδῶν, ταῦτα δέ οἵ ἐστι λίθου λευκοῦ. ἐνταῦθα ἔχει τιμὰς καὶ ὁ Σωσίπολις ἐν ἀριστερᾷ τῆς Τύχης, ἐν οἰκήματι οὐ μεγάλῳ· κατὰ δὲ ὄψιν ὀνείρατος γραφῇ μεμιμημένος ἐστὶν ὁ θεός, παῖς μὲν ἡλικίαν, ἀμπέχεται δὲ χλαμύδα ποικίλην ὑπὸ ἀστέρων, τῇ χειρὶ δὲ ἔχει τῇ ἑτέρᾳ τὸ κέρας τῆς Ἀμαλθείας.
The Eleans also have a sanctuary dedicated to Fortune. In the portico of the sanctuary stands a very large image, a wooden statue covered with gold, except on the face, the extremities of the hands, and the feet, which are made of white marble. Sosipolis is also honoured here, situated at the left side of Fortune within a small chamber. The god is depicted according to the appearance he had in a dream: as a child in age, he is clothed in a cloak spangled with stars and holds in one hand the horn of Amaltheia.
