The twelve essays collected here follow two fils rouges: on the one hand the theoretical debate about periodizations (Franco, Lipner, Oetke, Bronkhorst, and partly also Pinchard and Eltschinger), on the other hand the discussion of specific instances of periodization (Patil, Eltschinger,
Clavel, Pinchard), most notably of Erich Frauwallner's periodization (Franco, Motegi, Oetke, Bronkhorst).
