A beautiful woman is punishing an ugly one, choking her with one hand and with the other striking her with a staff. It is Justice who thus treats Injustice. Two other women are pounding in mortars with pestles; they are supposed to be wise in medicine-lore, though there is no inscription to them. Who the man is who is followed by a woman is made plain by the hexameter verses, which run thus:–
Idas brings back, not against her will,Fair-ankled Marpessa, daughter of Evenus, whom Apollo carried off.
