The historical landscape of the Greeks was bounded to the north by the Scythians, a fierce race renowned for milking mares (Hesiod Fr. 55 Rzach), for drinking wine without water (Hdt. vi. 84; Athenaeus 427 a–c), and for living not in fixed houses but in house-wagons, the Mongol yurt (Aeschylus, Prom. Vinct. 709 sq.; Hdt. iv. 46). Plato mentions them along with the Thracians as representatives of those in whom the spirited part of the soul predominates, meaning that they acted with indomitable energy but without their actions being guided by reason (Rep. 435b). The Athenians, quick to espy anyone's good points, employed them as policemen (Aristoph. Thesm. 1017, Lys. 451).
