The Sārāvalī of Kalyāṇavarman is a foundational compilation of Indian astrology, dating to ca.
[3] Utpala alias Bhattotpala quotes Kalyana-varman in his commentaries on Varahamihira's Brhat-samhita and Brhaj-jataka.
[6] For example, a manuscript dated to c. 1632 CE (Vikrama Samvat 1575) states that Sārāvalī had been incomplete for "hundreds of years" before Utpala completed it.
Katre, the use of the plural term "hundreds" indicates that Utpala lived at least 300 years after Kalyana-varman.
Therefore, Shastri theorizes that "hundreds" in this context refers to a long period of time in generic sense.
