"When an Avar made a journey, he did not cause either a horse or a steer to be harnessed, but gave command instead that three of four or five women should be yoked to his cart and be made to draw him. Even thus they harassed the Dulebians. The Avars were large of stature and proud of spirit, and God destroyed them. They all perished, and not one Avar survived. There is to this day a proverb in Rus' which runs, "They perished like the Avars.""
