James Prinsep was on officer in which of the following department of the British East India company?

Mint

The 1830s witnessed remarkable developments in Indian epigraphy when James Prinsep, an East India Company mint officer, successfully deciphered the ancient scripts of Brahmi and Kharosthi found on inscriptions and coins. He revealed that these inscriptions frequently mentioned a king known as Piyadassi, meaning "pleasant to behold," and occasionally referred to as Asoka, a renowned ruler from Buddhist texts.

Prinsep's breakthrough sparked a new wave of investigations into early Indian political history, with both European and Indian scholars using inscriptions and texts in various languages to reconstruct the genealogies of prominent dynasties that had governed the subcontinent. Consequently, the foundations of political history were established by the early decades of the twentieth century.
