Pausanias Analysis

ἐπεθύμησεν ἡ Καλλιρόη τῆς Ἐριφύλης οἱ γενέσθαι τὸν ὅρμον καὶ διʼ αὐτὸ ἐς τὴν Φηγίαν τὸν Ἀλκμαίωνα ἔστειλεν ἄκοντα, καὶ αὐτὸν ὑπὸ Φηγέως τῶν παίδων Τημένου καὶ Ἀξίονος δολοφονηθέντα ἐπέλαβεν ἡ τελευτή.

The sentence has coordinated narrative predicates; the infinitival phrase after ἐπεθύμησεν is textually difficult, especially οἱ, while the final accusative participial clause describes Alcmaeon being murdered before death overtook him.

τοῦ Φηγέως δὲ οἱ παῖδες τῷ Ἀπόλλωνι ἀναθεῖναι τῷ ἐν Δελφοῖς λέγονται τὸν ὅρμον.

The impersonal passive λέγονται takes the accusative subject τὸν ὅρμον with infinitival complement ἀναθεῖναι; τοῦ Φηγέως modifies παῖδες, and the repeated dative article τῷ introduces a substantivized/elliptical recipient phrase, with ἐν Δελφοῖς modifying it.

καὶ ἐπὶ τούτων βασιλευόντων ἐν Φηγίᾳ τότε ἔτι καλουμένῃ τῇ πόλει Φηγίᾳ στρατεῦσαί φασιν Ἕλληνας ἐς Τροίαν·

Infinitival στρατεῦσαι is the complement of φασιν, with Ἕλληνας as its accusative subject; the genitive absolute ἐπὶ τούτων βασιλευόντων gives the temporal setting. The participle καλουμένῃ agrees with τῇ πόλει; the repeated Φηγίᾳ is an appositional/locative place-name, with slightly uncertain attachment.

σφᾶς δὲ οἱ Ψωφίδιοι τοῦ στόλου φασὶν οὐ μετασχεῖν, ὅτι αὐτῶν τοῖς βασιλεῦσιν οἱ Ἀργείων ἀπηχθάνοντο ἡγεμόνες, κατὰ γένος τε τῷ Ἀλκμαίωνι οἱ πολλοὶ προσήκοντες καὶ τῆς ἐπιστρατείας αὐτῷ κοινωνήσαντες τῆς ἐς Θήβας.

The infinitive μετασχεῖν is the complement of φασίν with σφᾶς as its accusative subject; ὅτι introduces the reported causal content. In the subordinate clause, ἡγεμόνες is the subject of ἀπηχθάνοντο, with οἱ Ἀργείων modifying it; the participles προσήκοντες and κοινωνήσαντες are coordinated supplements referring to οἱ πολλοί, while τῷ Ἀλκμαίωνι and αὐτῷ are dative complements. The second αὐτῶν is genitive possessive with τοῖς βασιλεῦσιν.
