THE Bakhshali Manuscripts, a collection of 70 odd leaves of birch bark, containing a wealth of mathematical methods, have finally been dated. The oldest of the three samples tested was written as early as the 3rd-4th century, placing it almost five centuries earlier than where most scholars had placed the manuscripts. This makes the Bakhshali Manuscripts the oldest recorded use of a large dot, the precursor of our current form of zero. The other two fragments were dated as late 8th, and 10th century compositions, a gap of five to six centuries between the earliest one.
