Passage 1.42.6
ἔστι δὲ καὶ Δήμητρος ἱερὸν Θεσμοφόρου. κατιοῦσι δὲ ἐντεῦθεν Καλλιπόλιδος μνῆμά ἐστιν Ἀλκάθου παιδός. ἐγένετο δὲ καὶ ἄλλος Ἀλκάθῳ πρεσβύτερος υἱὸς Ἰσχέπολις, ὃν ἀπέστειλεν ὁ πατὴρ Μελεάγρῳ τὸ ἐν Αἰτωλίᾳ θηρίον συνεξαιρήσοντα. ἀποθανόντος δὲ ἐνταῦθα πρῶτος τεθνεῶτα ἐπύθετο ὁ Καλλίπολις, ἀναδραμὼν δὲ ἐς τὴν ἀκρόπολιν--- τηνικαῦτα δὲ ὁ πατήρ οἱ τῷ Ἀπόλλωνι ἐνέκαεν--- ἀπορρίπτει τὰ ξύλα ἀπὸ τοῦ βωμοῦ· Ἀλκάθους δὲ ἀνήκοος ὢν ἔτι τῆς Ἰσχεπόλιδος τελευτῆς κατεδίκαζεν οὐ ποιεῖν ὅσια τὸν Καλλίπολιν καὶ εὐθέως ὡς εἶχεν ὀργῆς ἀπέκτεινε παίσας ἐς τὴν κεφαλὴν τῶν ἀπορριφέντων ἀπὸ τοῦ βωμοῦ ξύλῳ.
There is also a temple of Demeter Thesmophoros here. Descending from this place, there is the tomb of Callipolis, the son of Alcathous. Alcathous also had another son, older than this one, named Ischepolis, whom his father sent to assist Meleager in overcoming the beast in Aetolia. When Ischepolis died there, Callipolis was the first to hear of his brother's death, and, running up to the acropolis—his father was at that moment offering a burnt sacrifice to Apollo—he scattered the wood from the altar. Alcathous, still ignorant of the death of Ischepolis, judged that Callipolis had acted impiously, and, immediately driven by anger, killed him by striking his head with one of the logs that had fallen from the altar.
