Petiția se adresează: Bürgermeister Hans-Rudi Bührle

We are the administrators of the forum "Yi Jing - I Ching - Noi e il Mutamento", an Italian-language community of enthusiasts and scholars of the ancient Chinese Book of Changes. We would like to inform the Municipality of Bad Boll (Baden-Württemberg, Germany), which hosts the tomb of Richard Wilhelm (1873-1930), a world-famous sinologist, known above all for being the author of the most widespread version of the I Ching, and his wife Salome Blumhardt, that the funerary monument (fig. 1) of its illustrious citizen currently presents an evident error in the arrangement of the covering slabs. In fact, a well-known sequence of symbols (called Trigrams) should be read there, which is called the houtian bagua (Sequence of the Later Heaven) in Chinese tradition (fig. 2). This sequence, which can be seen in its correct form in a previous photograph, has been altered by the exchange of two corner slabs (fig. 3), probably during restoration work.
