Garcin De Tassy’s (1794-1878) foundational work on Urdu language and literature as well as the study of Islam is a monumental contribution to Oriental Studies. Of great value to Urdu is his book Histoire de la Litterature Hindouie et Hindoustanie , which was first published in 1839 and later in 1847, 1870 and 1871. However, even until ninety years later, the book was not translated into Urdu. Its first Urdu translation was initiated at the Karachi University’s Department of Urdu in 1960. It was translated into Urdu directly from the French by Lilian S. Nazroo. It was presented in 1960 in the Karachi University as a doctoral research paper but remained unpublished for the next fifty years. This article presents a critical analysis of this Urdu translation.
