From Brewer's Dictionary of Phrase and Fable
a son of Ares.
Bistonians 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.
