Zirkoff, Boris
Panini. Greatest Hindu grammarian, fl. in the extreme Northwest of India at about the middle of the 4th century B. C., although this date is very uncertain. His grammatical work, the Ashtddhyayi (See App. p. 362), is not only the earliest grammar extant of any language, but one of the greatest grammatical works ever produced.
