mozart's opera la clemenza di tito was commissioned by the estates of bohemia as part of the festivities that accompanied the coronation of maria luisa and her husband leopold as king and queen of bohemia in prague on 6 september 1791. in musical circles, maria luisa is famous for her putative denigration of mozart's opera as "german rubbish" ("una porcheria tedesca"), however no claim that she made this remark pre-dates the publication in 1871 of alfred meissner's "rococo-bilder: nach aufzeichnungen meines grossvaters", a collection of stories about cultural and political life in prague in the late eighteenth and early nineteenth centuries.
