This commentary on the uttarakhaṇḍa of the BPH is extraordinarily rich in quotations from early astrologers, astronomers, and mathematicians; aside from those astrologers already discussed, Govindasvāmin cites Kṛṣṇa⁴⁴ (who may be identical with the author of the Kṛṣṇiya or Cintājñāna⁴⁵ which was extremely popular in Kerala), Bhagadatta,⁴⁶ Cirantana Yavana, Yavaneśvara (who is different from Sphujidhvaja, though the latter is also quoted by Govindasvāmin), and Haridatta (the seventh century astronomer, who evidently also wrote on astrology). The names of and quotations from the works of a few more authorities on \*jātaka\* from this early period can be found in Bhaṭṭotpala’s Jagaccandrikā; they are Yama (on BJ 8, 3), Vaṅkālaka⁴⁷ (on BJ 15, 1), and Śrutakīrti (on BJ 1, 7; 8, 9; 13, 3; and 21, 3). - [Previous: c7.59](https://indike.org/pramana/ins.science.pingree-1981.c7.59) - [Next: c7.61](https://indike.org/pramana/ins.science.pingree-1981.c7.61) - [Up: c7](https://indike.org/pramana/ins.science.pingree-1981.c7) ## Linked texts (3) - [Bṛhajjātaka](https://indike.org/pramana/in.astro.hora.yavana.brhajjataka.1.7) — Varāhamihira, Sanskrit - [Sārāvalī](https://indike.org/pramana/in.astro.hora.yavana.saravali) — Kalyāṇavarman, Sanskrit - [Kṛṣṇīya](https://indike.org/pramana/in.astro.prasna.krsniya) — Kṛṣṇanātha, Sanskrit --- Source: [https://indike.org/pramana/ins.science.pingree-1981.c7.60](https://indike.org/pramana/ins.science.pingree-1981.c7.60) · Pramāṇa
