The French painter Antoine Watteau (1684-1721) was the catalyst of the Regency period of the rococo style. His painterly language is an elegant camouflage of strong emotion by kindly sentiments and gentle manners.
Jean Philippe Rameau (1683-1764) was a French theoretician of music and a composer. His theoretical works provided the scientific basis for the development of traditional, functional harmony in the 18th century. His operas were the first national creations to rival those of Lully.
