The Selden Map held by the Bodleian Library in Oxford, where it has been kept since 1659. This beautifully illustrated manuscript map shows East and Southeast Asia and marks maritime trading routes in the form of lines across the region. It was made in the first half of the seventeenth century somewhere in East or Southeast Asia.
