"ten vales divided is the ground"
This circle, contained multiple levels for various crimes. Inside of the circle were ten (10) "bolgias", or "pouches" where the sinners lay - all guilty of "fraud" of one sort or another. They may be liars, hypocrites, or thieves. "On the grim rocky ground [of the first bolgia], I saw horned devils armed with heavy whip Which on the sinners from behind they plied." These sinners were guilty of pandering, or "pimping", and as they beat their whores, they themselves would forever be beaten.
