ĀCĀRYA JAYADEVA'S TREATMENT OF PERMUTATIONS
AND COMBINATIONS Ācārya Jayadeva and His Time
Acārya Jayadeva is a well known writer on Sanskrit prosody.
He has been mentioned or quoted by Svayambhū (prior to 1000 A. D.), Nāgavarman (the author of Chandombudhi (990 A. D.), Abhinayagupta (c. 1000, in his commentary on Bharata's Nāțya sästra), Nami sādbu (c. 1068, the author of a commentary on Rudraga's Kavyalankära).
Probably he is the author mentioned twice by Halāyudha (late 10th century), a commestator of Pingala. Again probably he is the author whose definitions have been quoted by Bhattotpala (c. 966, in his commentary on Varābamihira's Brhatsamhitā). He may even have been known to Varāhamihira (but this is not certain).
Again, he is mentioned4 or quoted by Jayakirti (c. 1000), Gopāla (prior to 1135 AD , in his commentary on Virahānka's Všttajatisa muccaya), Trivikrama (c. 1164, in bis commentaży on Kedāra's Vittaratvākara), Hemacandra (c. 1150, in his commentary on his own Chandonušāsagia) and Sulbaņa (c. 1189 in his commentary on Kedāra's Vșttaratnakara).
Later on also he is mentionedá or quoted by the unknown Jain author of Kavidarpana and Rāmcandra Vibudha (16th century) and N. Bhatta (c. 1545) in their commetaries on Kedāra's Vșttaratnākara.
From all these references and quotations it is clear that Jayadeva lived sometimes before 900 A. D. and perhaps even before 600 A. D.
