We have only one work by Brahmadeva and this is Karanaprakasa which is a commentary on the Aryabhatiya by Aryabhata I.
Brahmadeva's work is in nine chapters and it follows the contents of the original Aryabhatiya.
Topics covered include the longitudes of the planets, problems relating to the daily rotation of the heavens, eclipses of the sun and the moon, risings and settings, the lunar crescent, and conjunctions of the planets.
One of the kings was named Brahmadeva, which means the Brahma (supreme force of creation), and his land contained three rivers.
This extraordinary account brought tremors to the heart of King Brahmadeva, who was terrified even further when King Precious Canopy's men began to beat the drums that signaled lunch time.
Brahmadeva began to tremble, thinking that they were going to seize and kill him, and stood up to apologize, his limbs weak and quivering.
