ABSTRACT
As already mentioned (Chapter 7, pp. 151, 157–160), although the research results Thomas Zimmer presented in his 1999 work could not be incorporated in a satisfactory discussion offered in this book, they still deserve a few remarks. Zimmer’s book was published almost twenty years later than the works of the two Russian scholars Gurevich and Zograf (1982) – one of many reasons why Zimmer’s study is far superior. Zimmer concentrated exclusively on eight selected bianwen discovered in Dunhuang, providing both possible earliest and latest dates of their origin.
