PILES, Dialogue sur le coloris, 1699

Second edition.
"The discourse on art was born in France during the reign of Louis XIV thanks to two antagonistic figures: Félibien (1619-1709) and Roger de Piles (1635-1709). The latter became the major theoretician of color in the quarrel which opposed Rubenists and Poussinists during the last three decades of the 17th century." (trad. from Bernard Teyssèdre, "Roger de Piles and The debate on color, 1957)

De Piles supports Rubens by arguing that color is the major subject of painting and must come before drawing.
