The eyes are always a problem in sculpture. What do you do about them? The ancient Greek artist (or ancient Roman artist) of Diana of the Temple of Apollo of Pompeii had one solution.

Perhaps, Aristotle's eyes were painted in. Greek sculpture and Roman sculpture was usually painted (Wikipedia: Greek sculpture: Painting of sculpture). That the ancient Greeks and Romans usually painted sculpture was long suspected, but only in the late 20th century did scientific studies show that it was the normal practice. Typically, only traces of remain on surviving sculpture. Painting sculpture to us moderns seems bizarre, garish, and vulgar.
