The text has been attributed to the 16th century astrologer-astronomer
Nilakantha by earlier sources, but later research suggests that the original
Prashna-tantra was written by Samara-simha in the 13th century, largely based on
Sahl ibn Bishr's 9th century text ''Kitāb fi l-masa'il wa-l-ahkam
. Nilakantha or one of his students may have compiled the hybrid version of Prashna-tantra'' to complement the two volumes of Nilakantha's
Tajika-Nilakanthi, by adding excerpts from other texts to the original work. These other texts include mainly non-Tajika Sanskrit works such as Bhattotpala's
Prashna-jnana, Padma-prabha-suri's
Bhuvana-dipaka, Narayana-dasa Siddha's
Prashna-vaishnava, Prthyu-yashas's
Shatpanchashika,
Varaha-mihira's
Brhadyatra, Ramachandra's
Samara-sara, Yaska's
Nirukta,
Prashna-chintamani,
Prashna-dipaka,
Prashna-pradipa,
Trailokya-prakasha, and
Jnana-muktavali, among others. == Contents ==
