The numerous studies of the love for India entertained by the main actors of German romanticism have rarely developed the tension between their search for an Urreligion and an Ursprache, through philology and linguistics applied to the religious texts of South Asia, and that for an Ursymbolik, through the comparative study of mythologies and of the representations of divinities other than those in Greek art. If the Indo-European filiation (before it was named) managed to reconfigure the religious themes, it had difficulties articulating a questioning of Greece’s plastic and aesthetic autonomy. This paper focuses on studying this phenomenon through the dialogue between Aloys Schreiber, defender of classicism, and the Indophile Joseph Görres regarding the « Indo-European » nature of the works of the German artist Philipp Otto Runge.
