Pindar, Isthmian 4.60-64
For him, we offer a feast before the Alektran gates and leave
a pile of newly-made wreaths on his altars
as fires for the eight bronze-speared dead
—the sons whom Megara, Kreon’s daughter bore.
τῷ μὲν Ἀλεκτρᾶν ὕπερθεν
δαῖτα πορσύνοντες ἀστοί
καὶ νεόδματα στεφανώματα βωμῶν αὔξομεν
ἔμπυρα χαλκοαρᾶν ὀκτὼ θανόντων,
τοὺς Μεγάρα τέκε οἱ Κρεοντὶς υἱούς·
Schola BD on Pindar, 4.104g
When it comes to the sons Herakles had with Megara, Lysimakos says that some people claim they were not murdered by Herakles but by some foreigners. Others Claim that king Lykos killed them. Sokrates says that they were murdered by Augeas.
There are also debates about the number of the children. Dionysios in the first book of his Cycle says that they were Thêrimakhos and Dêikoôn. To these, Euripides adds Aristodêmos. But the Argive Deinias says that the sons were Thêrimakhos, Kreontiadês, Dêikoôn, and Deion. But Pherecydes claims in his second book that they are Antimakhos, Klumenos, Glênos, Thêrimakhos, Kreontiadês, claiming that they were thrown into a fire by their father.
Batôn records in the second book of his Attic History that the sons’ names were Poludôros, Anikêtos, Mêkistophonos, Patroklês, Toxokleitos, Menebrontes, and Khersibios. Herodoros claims that Herakles went insane twice. He was purified first by Sikalos, according to Menekratês, who says that he had eight sons, and that they were not called Heraclids—for he was not yet named Herakles, but Alkaiads.”
τῶι μὲν ᾽Αλεκτρᾶν ὕπερθεν δαῖτα πορσύνοντες ἀστοὶ καὶ νεόδματα στεφανώματα βωμῶν αὐξομεν ἔμπυρα χαλκοαρᾶν ὀκτὼ θανόντων, τοὺς Μεγάρα τέκε οἱ Κρεοντὶς υἱούς] περὶ τῶν ῾Ηρακλέος ἐκ Μεγάρας παίδων Λυσίμαχός φησί τινας ἱστορεῖν μὴ ὑπὸ ῾Ηρακλέος ἀλλ᾽ ὑπό τινων δολοφονηθῆναι ξένων· οἱ δὲ Λύκον τὸν βασιλέα φασὶν αὐτοὺς φονεῦσαι· Σωκράτης δὲ ὑπὸ Αὐγέου φησὶν αὐτοὺς δολοφονηθῆναι. καὶ περὶ τοῦ ἀριθμοῦ δὲ διαλλάττουσι. Διονύσιος μὲν ἐν πρώτωι Κύκλου Θηρίμαχον καὶ Δηικόωντα· Εὐριπίδης δὲ προστίθησιν αὐτοῖς καὶ ᾽Αριστόδημον· Δεινίας δὲ ὁ ᾽Αργεῖος Θηρίμαχον Κρεοντιάδην Δηικόωντα Δηίονα. Φερεκύδης δὲ ἐν δευτέρωι ᾽Αντίμαχον Κλύμενον Γλῆνον Θηρίμαχον Κρεοντιάδην, λέγων αὐτοὺς εἰς τὸ πῦρ ὑπὸ τοῦ πατρὸς ἐμβεβλῆσθαι. Βάτων δὲ ἐν δευτέρωι ᾽Αττικῶν ῾Ιστοριῶν Πολύδωρον ᾽Ανίκητον Μηκιστόφονον Πατροκλέα Τοξόκλειτον Μενεβρόντην Χερσίβιον. ῾Ηρόδωρος δὲ καὶ δίς φησι μανῆναι τὸν ῾Ηρακλέα. ἐκαθάρθη δὲ ὑπὸ Σικάλου, ὥς φησι Μενεκράτης, λέγων αὐτοῦ τοὺς υἱοὺς εἶναι ὀκτώ, καὶ καλεῖσθαι οὐχ ῾Ηρακλείδας—οὐδέπω γὰρ ῾Ηρακλῆς ὠνομάζετο—ἀλλ᾽ ᾽Αλκαίδας.
