Understanding the Baroque Term
We use the term Baroque in two ways: as an aesthetic category applicable to any era, contrasting with the Classic, and as the prevalent artistic style in Europe and America during the 17th century and the first half of the 18th century.

Key contrasts defining Baroque versus Classicism include:
