It's the year 1658, a young French physician sets sail from Egypt with the goal of reaching the kingdom of Abyssinia (modern-day Ethiopia) via the Red Sea. Monsieur Bernier soon abandons his plan and ends up at the port in Surat in India, the subcontinent where he'd make rather influential acquaintances.
Bernier meticulously narrates the events of the power struggle amongst princes of the Mughal empire after the emperor Shah Jahan has been maimed with illness. And as he travels through the empire, he through a series of letters addressed home richly describes the various echelons of the empire, the customs of the royal court and its courtiers, matters of trade, myths and traditions of the gentile masses, and even the events of nature which he sets forth to explain with great scientific temper.
Apart from the writings of Bernier and the translation, the book has been smartly edited, and avid readers would for hours find themselves fondly rummaging through the footnotes and the appendices.
