Heracles and the Mares of Diomedes

Eurystheus pits his cousin against a son of Ares and some man-eating horses.

Introduction

This post is number 8 in the series Twelve Labours of Heracles

After seven failed attempts, King Eurystheus has still not rid himself of his cousin Heracles. Perhaps, he thinks, combat with a warrior-king of divine birth, some man-eating mares, and a savage tribe would to be enough; and certainly, things do not look good for our hero at first.

ARES, the god of war,* had a son named Diomedes, lord of the Bistones, a warrior-tribe that lived near Lake Vistonida in Thrace.* Down by the sea Diomedes kept a string of savage mares, chained to bronze mangers in which he gave them man’s flesh to eat.

Understandably, in sending Heracles to steal these man-eating mares from their warlike master and his barbarous tribe, King Eurystheus hoped that even his cousin would meet his match.

Heracles began by driving the mares into the sea, but to his horror they dragged his friend Abderus in after them, who drowned while Heracles fended off the enraged Bistones. In a fury of vengeance he fed Diomedes to his own mares, which instantly became tame, and followed Heracles back meekly to Tiryns.

Having no real use for them, Eurystheus let the placid mares wander onto Mount Olympus, where wild beasts devoured them, though rumour had it that one of their descendants became a favourite of Alexander the Great.

Based on ‘Library’ II.5.8 by Pseudo-Apollodorus (ca. 1st or 2nd century AD) and ‘Myths and Legends of Ancient Greece and Rome’, by E.M. Berens.

Ares in Greek mythology corresponds roughly to Mars in Roman mythology; but for the Greeks, Ares was very much the god of brute force and violence only; the deity of military strategy and generalship was his sister Athena.

Précis
Heracles was sent to Thrace by Eurystheus, to kidnap the man-eating mares of King Diomedes, which proved unexpectedly easy when, angered by the death of his friends, Heracles threw Diomedes himself to the mares, after which they became suddenly tame. Frustrated once again in his campaign to see Heracles ‘accidentally’ killed, Eurystheus let the horses go.

Express the ideas below in a single sentence, using different words as much as possible. Do not be satisfied with the first answer you think of; think of several, and choose the best.

Eurystheus told Heracles to steal Diomedes’s horses. Diomedes was a son of Ares, god of war. Eurystheus knew.
