Kṛṣṇa Daivajña was a 16th-17th century Indian astrologer-astronomer-mathematician from Varanasi patronized by the Mughal Emperor Jahangir.
Several of his nephews, these include Munīśvara, Gadādhara and Nārāyaṇa, have composed reputed works on astrology and astronomy.
In his commentary on Jātakapaddhati, he used the birth date of Abdur Rahīm Khān-i Khānān, an influential courtier of the third Mughal emperor Akbar, to illustrate some of his astrological computations and observations.
T. Hayashi, a Japanese historian of Indian mathematics, in his forward to the critical edition of Bījapallava, writes: ".
As already pointed out, in this work, to illustrate his arguments, Kṛṣṇa Daivajña took the birth date of Abdur Rahīm Khān-i Khānān, a prominent courtier of the third Mughal emperor Akbar.
Analyzing the image, S. R. Sarma has come to the conclusion that one of the four astrologers, the one who is depicted as drawing the birth chart, should be Kṛṣṇa Daivajña.
