Solution:James Prinsep and George Turnour were both instrumental in identifying 'Devanam Piya' with the Maurya King Ashoka. James Prinsep, in the 19th century, deciphered the Brahmi script used in Ashokan inscriptions, revealing that the term 'Devanam Piya' referred to a ruler. Meanwhile, George Turnour, a British civil servant and historian, studied Sri Lankan Buddhist texts, particularly the Mahavamsa, which helped in associating Ashoka with the inscriptions. Their combined efforts led to the recognition of Ashoka as the historical figure behind the edicts, contributing significantly to the study of ancient Indian history.
