This chart of the Red Sea, probably dating from the seventeenth century, was used by a Gujarati pilot engaged in trade and the transport of Muslim pilgrims to Jeddah during Hajj. Acquired by Alexander Burnes, an officer in the East India Company, it was presented in 1835 to the Royal Geographical Society. The chart is currently being examined as part of a research project on Indigenous maps in the collections of the Royal Geographical Society (with IBG), by Joy Slappnig (Royal Holloway, University of London) which aims to re-conceptualise them as artefacts of encounter and exchange. https://bit.ly/2EqNWTD
