James Fergusson’s (1808-86) books on architectural history were widely read in Britain, America, India and Australia. He was born in the Scottish town of Ayr and educated at the Royal High School in Edinburgh. Family connections made it possible for him to work and travel in India between 1829 and 1839. Fergusson wrote notes on a vast array of the country’s antiquities. He began publishing this material in London during the 1840s and completed a comprehensive survey of the subject in 1876, the History of Indian and Eastern Styles of Architecture. For him, each Indian architectural style was classified according to its region and period, as well as the religion and race of the builders. This essay considers the Scottish background for Fergusson’s writings of India, particularly as set out in letters and a diary, written during his journeys within the country. He discerned an ideal, in which the arts of agriculture and architecture are similarly practiced in a logical manner. Fergusson was especially impressed by the way workers in India respected common sense when constructing and adorning a building. Such an edifice was described as “pure”; and conformed to his mature definition of a “true style” of architecture.
