Hesiod, Shield of Heracles

But Athena the daughter of aegis-bearing Zeus came to meet Ares, wearing the dark aegis, [445] and she looked at him with an angry frown and spoke winged words to him. “Ares, check your fierce anger and matchless hands; for it is not ordained that you should kill Heracles, the bold-hearted son of Zeus, and strip off his rich armor. Come, then, cease fighting and do not withstand me.” [450] So said she, but did not move the courageous spirit of Ares. But he uttered a great shout and waving his spears like fire, he rushed headlong at strong Heracles, longing to kill him, and hurled a brazen spear upon the great shield, for he was furiously angry because of his dead son; [455] but bright-eyed Athena reached out from the chariot and turned aside the force of the spear. Then bitter grief seized Ares, and he drew his keen sword and leaped upon bold-hearted Heracles. But as he came on, the son of Amphitryon, unsated of fierce battle, [460] shrewdly wounded his thigh where it was exposed under his richly-wrought shield, and tore deep into his flesh with the spear thrust and cast him flat upon the ground. And Panic and Dread quickly drove his smooth-wheeled chariot and horses near him and lifted him from the wide-pathed earth [465] into his richly-wrought car, and then straight lashed the horses and came to high Olympus. But the son of Alcmena and glorious Iolaus stripped the fine armour off Cycnus' shoulders and went, [470] and their swift horses carried them straight to the city of Trachis. And bright-eyed Athena went from there to great Olympus and her father's house. As for Cycnus, Ceyx buried him and the countless people who lived near the city of the glorious king, in Anthe and the city of the Myrmidons, and famous Iolcus, [475] and Arne, and Helice: and many people were gathered doing honor to Ceyx, the friend of the blessed gods. But Anaurus, swelled by a rain-storm, blotted out the grave and memorial of Cycnus; for so Apollo, Leto's son, commanded him, because he used to watch for and violently despoil the rich hecatombs [480] that any might bring to Phyto.
