In India proper, although they were in use amongst the astronomers and mathematicians from the 3rd or 4th century A.D. onwards, it did not become the fashion to use them in inscriptions till a much later date. The earliest Hindu inscriptions using these numerals are dated 813 A.D.² and 842 A.D.³ In the following century they are used in the plates issued by the Eastern Chalukya Amma II, in 943 A.D.⁴ In later times the epigraphic instances become more frequent. The notation is also found in several manuscripts in which dates are given in verse.⁵
