Explanation:
The classical era of Indian astronomy begins in the late
Gupta era, in the fifth–sixth centuries. The Panchasiddhantika
(Varahamihira, 505 CE) approximates the method for
determination of the meridian direction from any three positions
of the shadow using Gnomon or Sanku.
Once, while visiting the court of Emperor Muhammad
Shah, Maharaja Jai Singh II of Jaipur overheard a loud argument
about how to calculate the most astronomically advantageous
date for the purpose of the emperor beginning a journey. To
the Maharaja, the debate highlighted the need for education in
the field of astronomy and for an observatory that could make
accurate astronomical calculations. The idea for the Jantar
Mantars or calculation instruments was born.
The Jantar Mantar consists of a number of structures
in stone, brick and marble, each of them marked with
astronomical scales and designed to serve a specific purpose.
Of the observatories originally built at Delhi, Jaipur, Mathura,
Ujjain and Varanasi, all observatories still exist except the one
in Mathura.
Among the devices used for astronomy was Gnomon,
known as Sanku, in which the shadow of a vertical rod is
applied on a horizontal plane in order to ascertain the cardinal
directions, the latitude of the point of observation and the
time of observation. This device finds mention in the works of
Varahamihira, Aryabhatta, Bhaskara, Brahmagupta, among
others.
The armillary sphere was used for observation in India
since early times, and finds mention in the works of Aryabhatta
(476 CE). The Goladipika—a detailed treatise dealing with
globes and the armillary sphere was composed between 1380–
1460 CE by Parameswara. Probably, the celestial coordinates
of the junction stars of the lunar mansions were determined by
the armillary sphere since the seventh century. There was also
a celestial globe rotated by flowing water.
