I want to know the answer to the following question:
What divided Asia on a similar basis?
All the background I'm provided with is that "Beyond the Ganges and Himalayas (including the Tien Shan) were Serica and Serae (sections of China) and some other identifiable far eastern locations known to the voyagers and geographers but not to the general European public.". Is that enough to answer the question?
Answer: no
