Roger de Piles (1635–1709) was a French art critic who decomposed the style and ability of 58 different artists into areas of composition, drawing, color, and expression, rating each artist on a 20-point scale in each category. Based on evidence from two data sets that together span from the mid-eighteenth century to the present, this article shows that De Piles' overall ratings have withstood the test of a very long period of time, with estimates indicating that the works of his higher-rated artists achieved both greater returns and higher critical acclaim than the works of his lower-rated artists.
