The Delight of Mathematicians

original: "Ganaka Ranjani"

Verse I meditate upon the all-pervading one, clothed in white, moon-colored, with four arms and a serene face, so that all obstacles may be stilled.
This is a traditional Sanskrit invocation to the deity Ganesha (the remover of obstacles) or Vishnu, used to ensure the successful completion of a task.

Victorious is the Sun, the soul of the universe and the source of the world’s birth, the natural ornament of the sky, who is adorned with a garland of a thousand rays resembling molten gold. (1)
As a work on astronomy and astrology, it is customary to praise the Sun (Savita/Surya), the primary celestial body used in calculations.

Having observed the infallible words spoken by the first sages and the great extent of their works, I have composed this to clearly state the meaning—neither too briefly nor too extensively, but in a very pleasing manner. (2)
The author explains his intent: to distill the vast, complex ancient Sanskrit astronomical texts (Siddhantas) into a more readable and balanced format.

Verse Residing always in the prosperous town named Tammuvaram, he is like a honeybee at the lotus feet of the holy Ramachandra.
A treasury of astrological science and a scholar, born of the "Stone-cart" lineage—which is like an ocean—he is named Kuppayya, son of Ramamba, of the Vapaga-ayana gotra.
