Red-figure painting on an Attic lekythos (oil vessel), dating to about
460 B.C., now in the Louvre Museum, Paris.
The figure represents the Trojan warrior Dolon, wearing a wolf skin.
The episode is narrated in the Iliad (X, 333-336), where Dolon
went overnight to the Greek campsite, but was intercepted by Odysseus
and Diomedes, caught and killed. According to Louis Gernet (1968) the
costume worn by the Trojan warrior recalls the wolf disguise proper
of many Indo-European warrior “fraternities”, that should
have existed also in archaic Greece, though no documentary evidence
has remained. In the Homeric poems the warriors are often compared to
wolves, of which they show the fierceness and courage during the fight.
For example, the Myrmidons, warriors in the retinue of Achilles, were
described as “wolves, raw-ravening beasts” (Iliad
XVI, 155-156).
