Passage 2.22.9
καὶ τὸ ἔχθος τὸ Ἀπόλλωνι διαμένον ἐς τοὺς αὐλητὰς ἔτι ἀπὸ Μαρσύου καὶ τῆς ἁμίλλης τοῦ Σιληνοῦ παυθῆναι διὰ τοῦτον δοκεῖ τὸν Σακάδαν. ἐν δὲ τῷ γυμνασίῳ τῷ Κυλαράβου καὶ Πανία ἐστὶν Ἀθηνᾶ καλουμένη καὶ τάφον Σθενέλου δεικνύουσι, τὸν δὲ αὐτοῦ Κυλαράβου. πεποίηται δὲ οὐ πόρρω τοῦ γυμνασίου πολυάνδριον τοῖς μετὰ Ἀθηναίων πλεύσασιν Ἀργείοις ἐπὶ καταδουλώσει Συρακουσῶν τε καὶ Σικελίας.
The longstanding hostility Apollo bore toward flute-players ever since Marsyas' contest, the silenus, is believed to have ceased because of this Sacadas. In the gymnasium of Cylarabus there is also an image of Athena called Pania, and the tomb of Sthenelus is shown there, as well as that of Cylarabus himself. Not far from the gymnasium stands a common tomb of those Argives who sailed with the Athenians against Sicily, aiming to reduce Syracuse and the whole island under their power.
