 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).
