Fascinating set of images of China, from teh collection of noted antiquarian Richard Gough.
fig.1. shows what appears to be the inlet on the coast of China, with one large island named ' I Lenur', plus various named settlements on the mainland.
fig.2. shows what appears to be positional references (latitude/longitude), there is also the word: 'Occidl' at the top which would suggest an abbreviation of 'Occidental' (North). There is something like 'Oriels' at the bottom suggesting 'South' ... Please see photos.
fig.3. shows an area of water with several islands, named in the key below the figure: CANTON, MACCAO, BECCA TIGRE and LINTIN. The islands and forts are labelled with Chinese characters.
This very unusual and highly collectable piece is one of Basire's engravings of The Richard Gough collection, printed in c.1780.
