Wölfflinin
Wölfflinin refers to a concept or theory attributed to the Swiss art historian Heinrich Wölfflin. Wölfflin is most famous for his work on the stylistic differences between the Renaissance and the Baroque periods. He developed a set of five pairs of concepts, or "formal categories," to analyze and distinguish these two artistic styles. These pairs are linear versus painterly, plane versus recession, closed versus open form, multiplicity versus unity, and clearness versus unclearness.
Linear style, characteristic of the Renaissance, emphasizes clear outlines and the distinctness of individual forms. In
Closed form in Renaissance art presents figures and objects as self-contained units, often centered and balanced.
