“Rubenisme: Artistic theory in France in the second half of the 17th century and the early 18th century, championing the primacy of color over line. Rubenistes opposed the Poussinistes, who favored line. Adherents of the two sides were named after Rubens and Poussin, who in their paintings had emphasized color and line, respectively.”
