Nietzsche, Burckhardt, Wölfflin

Two important figures when discussing Nietzsche and style:

Jacob Burckhardt (1818-97) was Friedrich Nietzsche's colleague at the University of Basel and Heinrich Wölfflin's professor. It is known Burckhardt and Nietzsche were fond of each other's company and maintained a correspondence for years. He published The Civilization of the Renaissance in 1860, a year after Darwin's publication of On The Origin of Species. Among his students, Heinrich Wölfflin. 

Heinrich Wölfflin
(1864-1945). 
In 1893 Wölfflin succeeded Burckhardt as professor of Art History. He left Basel to succede Hermann Grimm as the chair of art history in Berlin in 1901. In 1888 he wrote Renaissance and Baroque. It has been said that the Nietzschean opposition between Apollonian and Dionysian would have influenced Wölfflin in his canonization of the principles on style. His Formalism was apparently also influenced by developing theories in the psychology of perception and Empathy, particularly with the influence of psychologist/philosopher Theodor Lipp, with whom he studied.
