Nemesis

Rome, circa 150 A.D.
Marble
Getty Villa, Pacific Palisades, California

This statue of the goddess Nemesis treading on a foe is a forerunner of numerous portraits of Christian saints, mostly martyrs who overcame their persecutors through the witness given by their deaths.

Many other Roman statues of Nemesis include the spoked wheel. I have seen only one with a foe underfoot, but there are probably others.
