Brooke Boothby was a Derbyshire landowner. He is shown here reclining by a stream, holding a book with ‘Rousseau’ on its spine. This is a reference to Boothby’s pride in having published the Swiss philosopher’s autobiographical Dialogues. In deference to Rousseau’s ideas, Boothby shuns the ‘civilised’ world to think deeply, alone with nature. Boothby was part of an intellectual circle in the Midlands that pursued such ideals vigorously.
