The lower figure evidently represents Painting, for she has her pallette in the left hand, and, in the right, is holding a species of recipient in the form of a candelabrum, into which a Genius or a Muse is dropping a fresh colour, possibly alluding to the painting of this very poikilos, or painted portico, at Pompeii, which was probably considered as the perfection of the art.
