Long before Europeans emerged as the de facto rulers of the Indian subcontinent, a position wrested from the local populace through sheer force and guile, the average European, or firangi, was just a normal class of migrant in India. This statement is probably at odds with your mental picture of the average European settler in India - haughty, uncompromising in their foreignness, disdainful of local traditions.
But this wasn't always the case, especially in the era before colonial powers called the shots. Firangis, after all, predate colonialism, and have been migrating to the region ever since Vasco da Gama landed on the Malabar coast. Usually identified by their Christian faith (or origins, in the case of converts), these firangis came to be influenced by India in profound ways, each one with their own unique story of becoming Indian.
This book is a well researched collection of multiple accounts of becoming Indian, each involving different aspects of acclimitization (literal and figurative) to India, adapting to local culture, and processes of retraining one's natural instincts and lifestyle to suit the rhythms, whims, and demands of India's physical, social, and cultural geography. Each story is a mini biography in itself, complete with different historical sources, covering a wide range of languages, from Persian, to English, to Portuguese. Some of these names and stories are likely familiar, in bits and pieces.
From a Portuguese lady of the harem/doctor whose Delhi jāgīr still bears signs of her life, to a British comedic wit looking to write the ultimate travelogue, to a Dutch admiral of Travancore, to a haughty Italian origin Siddha doctor gone native, these stories show us a whole spectrum of becoming Indian, India itself, and more importantly, the common humanity that binds us all.
The level of depth, nuance, and research is quite impressive, especially taking into account the fact that for many of these stories, all we have are apocryphal, often innacurate and conflicting accounts by chroniclers with their own biases. From this confused haystack of unreliable stories, the author manages to find the needle that weaves the common thread of narrative.
The author, himself a firangi in India, describes vividly this process of becoming Indian, with anecdotes and experiences from his own life. Some of the metaphors he uses, for example the motif of bodies changing and food being ingested seem a little eccentric and are overused to the point of heavy handedness repeatedly throughout the book, making the flow awkward and forced at points. The writing is solid otherwise, no doubt in small part thanks to the author's own background.
Overall, a pretty interesting read that reveals a lot about how Indian society worked before colonialism took strong root in the region, showing us a vivid picture of culture, syncretism, and exchange that helps us understand better what it means to be Indian.
