Chakrapani bases his work on that of Vrinda who again follows closely the order and the pathology of the Nidana of Madhavacharya or Madhavakara. Chakrapani, himself a learned commentator of the Charaka and the Susruta, wrote his work in 1050 A.D It necessarily follows that Vrinda was a recognised authority at least before the time of Chakrapani and was preceded by Madhavakara who possibly flourished in the 8th century A.D.; for, Nidana was one of the medical treatises translated by the order of the Caliphs in the 8th century A.D. D. C. Bhattacharyya, on the basis of recently gathered evidences, however, placed Madhavakara sometime between 900 and 925 A.D. and Vrinda, between 975 and 1000 A.D.
