τὸν μὲν ἔπειτ᾽ εἴασε Διὸς ταλακάρδιος υἱός,
αὐτὸς δὲ βροτολοιγὸν Ἄρην προσιόντα δοκεύσας,
δεινὸν ὁρῶν ὄσσοισι, λέων ὣς σώματι κύρσας,
ὅς τε μάλ᾽ ἐνδυκέως ῥινὸν κρατεροῖς ὀνύχεσσι
σχίσσας ὅττι τάχιστα μελίφρονα θυμὸν ἀπηύρα:
ἐμ μένεος δ᾽ ἄρα τοῦ γε κελαινὸν πίμπλαται ἦτορ:
γλαυκιόων δ᾽ ὄσσοις δεινὸν πλευράς τε καὶ ὤμους
οὐρῇ μαστιόων ποσσὶν γλάφει, οὐδέ τις αὐτὸν
ἔτλη ἐς ἄντα ἰδὼν σχεδὸν ἐλθέμεν οὐδὲ μάχεσθαι:
τοῖος ἄρ᾽ Ἀμφιτρυωνιάδης, ἀκόρητος ἀυτῆς,
ἀντίος ἔστη Ἄρηος, ἐνὶ φρεσὶ θάρσος ἀέξων,
ἐσσυμένως: ὃ δέ οἱ σχεδὸν ἤλυθεν ἀχνύμενος κῆρ:
ἀμφότεροι δ᾽ ἰάχοντες ἐπ᾽ ἀλλήλοισιν ὄρουσαν.
ὡς δ᾽ ὅτ᾽ ἀπὸ μεγάλου πέτρη πρηῶνος ὀρούσῃ,
μακρὰ δ᾽ ἐπιθρῴσκουσα κυλίνδεται, ἣ δέ τε ἠχῇ
ἔρχεται ἐμμεμαυῖα, πάγος δέ οἱ ἀντεβόλησεν
ὑψηλός: τῷ δὴ συνενείκεται, ἔνθα μιν ἴσχει:
τόσσῃ ὃ μὲν ἰαχῇ βρισάρματος οὔλιος Ἄρης
κεκληγὼς ἐπόρουσεν: ὃ δ᾽ ἐμμαπέως ὑπέδεκτο.
424-442 Then the stout hearted son of Zeus let him be, and himself watched for the onset of manslaying Ares: fiercely he stared, like a lion who has come upon a body and full eagerly rips the hide with his strong claws and takes away the sweet life with all speed: his dark heart is filled with rage and his eyes glare fiercely, while he tears up the earth with his paws and lashes his flanks and shoulders with his tail so that no one dares to face him and go near to give battle. Even so, the son of Amphitryon, unsated of battle, stood eagerly face to face with Ares, nursing courage in his heart. And Ares drew near him with grief in his heart; and they both sprang at one another with a cry. As it is when a rock shoots out from a great cliff and whirls down with long bounds, careering eagerly with a roar, and a high crag clashes with it and keeps it there where they strike together; with no less clamour did deadly Ares, the chariot-borne, rush shouting at Heracles. And he quickly received the attack.
