The impact of the eighteenth century Jesuit astronomers on the astronomy of India and China.

Within a span of 60 years (1670 - 1730) a number of great observatories were erected in China and India, and a systematic programme of observing the heavens carried out under royal patronage. In these activities, along with the local scholars, several eminent Jesuit astronomers from Europe participated. The article examines the impact of these European astronomers, who brought the knowledge of Europe to the East, on the astronomical traditions of the two countries.
