The arimaspoi (arimaspians) were a tribe of one-eyed people who lived at the foot of the Rhipaion (Rhipaean) Mountains in northern Skythia (probably the Carpathians). They warred constantly with the gold-guarding Grypes (Griffins) of the mountains--winged beasts with the heads of eagles and the bodies of lions. According to Herodotos their name was derived from the Skythian words arima "one" and spou "eye".
