They were described as dark beings with gnashing teeth and claws and with a thirst for human blood. They would hover over the battlefield and search for dying and wounded men. A description of the Keres can be found in the Shield of Heracles (248–57): A parallel, and equally unusual personification of "the baleful Ker" is in Homer's depiction of the
Shield of Achilles (
Iliad, ix. 410ff), which is the model for the
Shield of Heracles. These are works of art that are being described. In the fifth century, Keres were portrayed as small winged sprites in vase-paintings adduced by J.E. Harrison (Harrison, 1903), who described apotropaic rites and rites of purification that were intended to keep the Keres at bay. According to a statement of
Stesichorus noted by
Eustathius, Stesichorus "called the Keres by the name
Telchines", whom Eustathius identified with the
Kuretes of Crete, who could call up squalls of wind and would brew potions from herbs (noted in Harrison, p. 171). The term
Keres has also been cautiously used to describe a person's fate. An example of this can be found in the
Iliad where
Achilles was given the choice (or
Keres) between either a long and obscure life and home, or death at Troy and everlasting glory. Also, when
Achilles and
Hector were about to engage in a fight to the death, the god
Zeus weighed both warriors'
keres to determine who shall die. As
Hector’s
ker was deemed heavier, he was the one destined to die and in the
weighing of souls, Zeus chooses Hector to be killed. During the festival known as
Anthesteria, the Keres were driven away. Their Roman equivalents were
Letum (“death”) or the
Tenebrae (“shadows”). ==Keres and Valkyries==
