This volume is a collection of nine previously unpublished papers delivered at the 2015 and 2018 Spontini symposia at Jesi, Maiolati Spontini, and Erfurt. The essays mainly investigate Spontini's late creative years and his critical reception in the 1820s-1840s, providing new insights into Spontini's role as both a composer and Generalmusikdirektor within the context of Berlin's musical life and German music festivals, his problematic relationship with Weber and Romantic opera, the extensive reworking of his earlier French works for the German stage, and his final achievement in music drama, Agnes von Hohenstaufen..
