Keshava flourished around 1496–1507.[1] He lived at
Nandigrama in western India. He was a son of Kamala-kara of
Kaushikagotra (clan), and a pupil of Vaijanatha (or Vaidyanatha).[1] His wife's name was Lakshmi.[2]
Ananta (fl. 1534): wrote Kalanirnayavabodha and a commentary (1534 CE) on
Varaha-mihira's Laghu-jataka[3]
Ganesha (born 1507): wrote a number of works during 1522–1554; his great-grandson - also called Ganesha - wrote Shiromani-prakasha[4]
Rama (fl. 1525/1550): his son Nrsimha (born 1548) wrote Graha-kaumudi, Kheta-muktavali, Graha-dasha-phala, Graha-dipika, Varsha-phala-dipika, Harsa-kaumudi (a commentary on Ganesha's Graha-laghava), and Hillaja-dipika[5]
Works and commentaries
Muhurtadipika by his son Ganesha lists several works written by Keshava. Sometimes, Ganesha's works are also attributed to Keshava. Works written by Keshava include:[1]
Graha-kautuka (1496 CE)
a commentary on Graha-kautuka
Graha-siddhi
Tithi-siddhi
Graha-chalana
Ganita-dipika
Jataka-paddhati, also known as Keshava-paddhati; Brhat-keshavi is an enlarged version of this text
Apparently a condensed version of Shripati's JKP: it is an extremely concise text containing only 42 verses, and was very popular as a handbook on mathematical calculations essential for jataka.[6]
A commentary on Jataka-paddhati
Tajika-paddhati, also known as Varsha-phala-paddhati or Tajika-keshavi
A work on
Tajika (Arabic-Persian astrology), it contains 26 verses[7]
Siddhanta-vasana
Kayasthachara-paddhati
Kundastaka-lakshana
