 Many artistic debates, recorded for posterity as a succession of querelles or quarrels—were highly polemical and often devolved into ad hominem satirical attacks. Among the most famous, one can list the quarrel over the play Le Cid and the Quarrel of the Ancients and the Moderns, both of which originated in the seventeenth century but which had implications for the next century. In painting, one could cite the quarrel between fans of Poussin, who privileged line, and fans of Rubens, who favored color. In opera, the Querelle des Bouffons pitted most Enlightenment philosophers, who preferred melody and a populist Italian style, against the fans of composer Rameau, who represented a more erudite approach to French harmony.
