Joseph Wright of Derby painted a portrait of a notable British subject, Sir Brooke Boothby, in 1781 that is extraordinary to me in its extravagant portrayal of a gentleman of sentiment and high fashion (which he was). He is portrayed reclining full length in a garden grove holding a book open (Rousseau I believe) and wearing a very large hat tilted to one side and in elegant but "suitable" clothes for a morning walk. It is for me a quintessential late 18th Century expression of the life of privilege removed from the salon to the beloved English garden which found its way to Versailles.

It must be great! Do you have any pictures of it? I would be curious to see it

I found it!
It's really delightful, and it seems to represent the XVIII century taste for sensibility and nature so well...
