Praśna-vidyā •
Praśna-cūḍāmaṇi, a 70-verse text on interrogative astrology • This is the only surviving original text written by Utpala • Also known by the names
Āryā-saptati (because it contains 70 verses in Arya metre),
Bhuvana-dīpaka,
Jñāna-māla,
Praśna-jñāna,
Praśnārya,
Praśnārya-saptati, and
Praśna-grantha • Utpala calls it by the name
Praśna-jñāna in the opening and concluding verses, which suggests that
Praśna-jñāna was the original title of the work • The colophons of some manuscripts suggest that it was a part of a larger work titled
Jñāna-māla •
Yuddha-jayārṇava-tantra, on victory in warfare • The colophon mentions Bhattotpala as its author. • Known from a Newari script palm-leaf manuscript copied by the astrologer (
daivajña) Sarvabala in 1270 CE; now at the National Museum, New Delhi • The work is in form of Shiva's answers to Parvati's questions, and is quoted in Raghu-nandana's
Jyotiṣa-tattva Besides
Saṃhitā-vivṛti and
Praśna-cūḍāmaṇi, Al-Biruni mentions the following works by Utpala, which are now lost: •
Rā.h.t.rakaraṇa, a handbook on astronomy •
Eduard Sachau restores the title as
Rāhunrā-karaṇa;
Ajay Mitra Shastri suggests this may be an error for
Rāhu-nirākaraṇa;
David Pingree suggests
Ārdharātrika-karaṇa •
Karaṇaghāta (or
Karaṇa-pāta), a handbook on astronomy • A commentary (
Ṭīkā) on Muñjāla's
Bṛhanmānasa •
S.rū.dh.w, a text on astronomy • The original Sanskrit title of the work is uncertain, but Sachau suggests
Śrūdhava, while Pingree suggests
Sūtra-dhāra. • Al-Biruni recommends the metrology described in this work, stating that it had been adopted by "ŚMY", another learned Indian astronomer. In
Jagac-candrikā, Utpala quotes verses from another of his lost works, on
Vastu-vidya (architecture). A verse found at the end of some manuscripts of Kalyana-varman's
Sārāvalī suggests that the original text remained incomplete for over three hundred years, before Utpala completed it. The manuscripts of Utpala's surviving works may contain some alterations and omissions by copyists. For example, Al-Biruni attributes a statement about the original name of
Multan to
Saṃhitā-vivṛti, but this statement is not present in the surviving manuscripts. According to this statement, Multan was originally called Yavana-pura, then Hamsa-pura, then Baga-pura, then Shamba-pura, then Mula-sthana (literally "original place"). == Legacy ==
