A recent reconsideration and recontextualization of Op Art, the expansive 2006 Optic Nerve exhibit at the Columbus Museum of Art, places the Anonima as the sole American collaborative group, along with the European Zero Group, Gruppo N, GRAV and others, who were examining new optical information at that time.
In 1960, Yvaral co-founded the Groupe de Recherche d’Art Visual (GRAV) with Julio Le Parc, François Morellet, Francisco Sobrino, Horacio Garcia Rossi and Joel Stein, seeking to develop a coherent abstract visual language composed of simple geometric elements.
Other examples of Passion Cantatas in the German-speaking world include such works as Gottfried August Homilius's Cantata "Ein Lämmlein geht und trägt die Schuld" HoWV 12 (1775), the Passion Cantata "Vor Harpe er bleven til Sorrig" with text by Johannes Ewald and music by the Bach critic Johann Adolf Scheibe, and the Sørge-Cantata ved Christi Grav "Herrens Salvede, som var vor Næses Aand" by the same librettist and composer.
