The concept of zero is referred to as shunya in the early Sanskrit texts and it is also explained in the Pingala'sChandah Sutra (200 AD). In the Brahma Phuta Siddhanta of Brahmagupta (400-500 AD), the zero is lucidly explained. The Hindu genius Bhaskaracharya proved that x divided by 0 = 4 (infinity) and that infinity however divided remains infinity. This concept was recognized in Hindu theology millennia earlier. The earliest recorded date for an inscription of zero (inscribed on a copper plate) was found in Gujarat (585 – 586 AD). Later, zero appeared in Arabic books in 770 AD and from there it was carried to Europe in 800 AD. The Indian place-value numeration with zero sign ranks among humanity's fundamental discoveries.
The ancient Hindu symbol of a circle with a dot in the middle, kmown as bindu or bindhu, symbolizing the void and the negation of the self, wae probably instrumental on the use of a circle as a representation of the concept of zero.
