Observers and observatories
Fellows of the Royal Society received intermittent reports on India and its customs from the earliest years of the Society's existence. Robert Moray FRS, for example, recorded in the Register Book of 1663 how the natives of Coromandel cooled their drinks by exposing them to the sun and wind.
The East India Company strengthened its hold on the subcontinent during the 18th century. This allowed British colonial adventurers such as Warren Hastings FRS to simultaneously absorb Indian culture and languages, while applying European scientific observation and collecting methods to the new environment. Sir Robert Barker FRS, noted in 1774 as being 'late Commander in Chief in Bengall', visited the impressive Brahmin observatory in Benares, sending back to London some superb illustrations for use in the Royal Society's Philosophical Transactions.
The Benares observatory was notable for being the most visible relic of Indian science, its geometrical forms architecturally distinct from prevailing styles. Barker, commenting on his visit, noted how understanding of the Brahmin tables predicting eclipses of the Sun and Moon was now limited to a small number of scholars, "who were in possession of certain books and records; some containing the mysteries of their religion, and others the tables of astronomical observations, written in the Skanskirrit language, which few understood but themselves".
The observatory was later seen and studied by the botanist and Royal Society President Joseph Dalton Hooker in the 19th century, by which time its great equinoctial sundial was in a sad state of disrepair.
More traditional architectural was also a subject of great interest to the Royal Society's Fellows. The Library holds a copy of one of the seminal 19th century works on the subject, the 'Essay on the architecture of the Hindus' by Ram Raz, an Indian clerk who taught himself the basics of Sanskrit, mathematics, geography and astronomy. Posthumously published in 1834, the book contains a wealth of detail derived from ancient Sanskrit treatises.
More practically, the East India Company's trading activities around the coast required accurate astronomical observations to aid navigation between Calcutta and Madras, a route notorious for shipwrecks. The astronomer William Petrie FRS set up an iron-and-timber observatory at his residence in Madras, equipping it with his own instruments. This was so successful in establishing a reference meridian in British India that it became India's equivalent of Greenwich and continued to play a major role in Imperial India throughout the 19th century.
