THE MATHEMATICAL CHAPTER OF THE AR YABHA TlYA : A COMPILATION OF ORAL MNEMONIC RULES ?

摘要

Aryabhata's Aryabhatlya (Ab), is a 5l century cornerstone astronomy treatise. It was continuously commented upon in the Indian sub-continent until the end of the 19~(th) century It gave rise to " schools " (paksa) who adopted its parameters3. However, like most texts from that period in the Indian subcontinent, we have little knowledge of its context of production, through what medium its author thought his text would be preserved, transmitted or displayed. The text is composed in versified sutras. These compact aphorisms are difficult to understand alone.
