The Hindu-Arabic Numerals c7.40

c7.40

A little later, but also in the sixth century, Varāha-Mihira² wrote a work entitled *Bṛhat Saṃhitā*³ in which he frequently uses *śūnya* in speaking of numerals, so that it has been thought that he was referring to a definite symbol. This, of course, would add to the probability that Āryabhaṭa was doing the same.
