MARSHALL, John. 16?? — 1677. British Traveller in India. Studies at Cambridge (M.A. Christ’s College). Employed by E.I.C. in India from 1668, apparently died there. Served in Bengal and under Job Charnock in Patna. Made a great number of notes on Indian customs, religion, etc., which were published only in the 20th century. He attempted to learn the Devanāgarī script and to translate the Bhāgavatapurāṇa from a Persian version. According to the Spectator “Marshall, from his diary, appears to have been a reserved, self-centred creature, with little interest in those with whom his lot was cast”.
