“Sculpture, music, text: Winckelmann, Herder, and Gluck’s Iphigénie en Tauride” by Simon Richter (Goethe yearbook VIII  pp. 157–71) considers Gluck’s opera in the context of Johann Joachim Winckelmann’s writings on the statue known as Laocoön, widely regarded as the measure for classical beauty in the second half of the 18th century, and Johann Gottfried Herder‘s writings on the human voice as a common origin for both music and language.
According to Richter, Gluck’s Iphigénie enacts a musical version of Winckelmann’s classical aesthetics, which in turn may have consequences for the way in which Iphigénie is performed, staged, and interpreted. Gluck is in every respect staging the allegorical triumph of his opera reform as the musical counterpart of Winckelmann’s classical aesthetics.
This year we celebrate the 250th anniversary of the publication of Winckelmann’s Geschichte der Kunst des Althertums (Dresden, 1764)! Winckelmann revolutionized the understanding of stylistic changes in Greco-Roman art and deeply influenced archaeological studies. His concept of edle Einfalt und stille Grösse (noble simplicity and quiet grandeur) put the excessive complexities of Baroque aesthetics to rest, influencing Gluck and others.
