From 1980 to 1985, Entwistle held the post of Universitair Docent at the University of Groningen in the Netherlands where he taught Hindi and courses on Indian civilization, iconography, religion and literature.
Entwistle's scholarly works on the study of India and Indian religions were marked by close attention to both philological linguistic issues of translation of texts and a broad emphasis upon the context of the material.
Entwistle's research was dependent on a thorough linguistic and literary training which formed the bedrock of his close attention to both philological issues of text and cultural context.
It's not just the scope of the work, which is wonderful, but the trustworthiness of all of it-those dense footnotes, which serve as the best meeting place for scholarship and thought about Braj over the course of the last 50 years, perhaps 100.
