Forgeries are rarely caught on style, because a competent forger matches style. They are caught on materials and methods that did not exist yet — a pigment first synthesised in the nineteenth century, or a perspective construction unknown before the fifteenth — which is evidence a connoisseur's eye cannot supply.
