Interior of a ship's cabin c.1819

Drawing. It is not clear of this is a warship day cabin but if so probably on a two decker, since there appear to be no stern gunports at what appears to be an upper level below the poop. The doors lead to the quarter gallery, with a stick barometer on ginbals showsn to the left. beyond sliding doors forming a bulkead to inner cabin space beyond. The collection of books, atlases and charts in portfolios is what one would expect in a captain's cabin though this one looks as if being packed up rather than in use.
