The Thracians; so called from Biston, son of Mars, who built Bistonia on the Lake Bistonis.
So the Bistonian race, a maddening train, Exult and revel on the Thracian plain; With milk their bloody banquets they allay. Or from the lion rend his panting prey; On some abandoned savage flercely fly, Seize, tear, devour, and think it luxury.
Pitt: Statius, Book ii.
