Sackville, Duke of Dorset, Charles

In the words of the DNB, "Dorset was a dissolute and extravagant man of fashion." He lived the public life of an 18c aristocrat--from Westminster to Christ Church to the Grand Tour to Whig politics, with a healthy dose of arts patronage, mistresses, a financially prudent marriage, and death in his late fifties. And then there's a single piece of cynical pastoral (the shepherds praise their mistresses only to learn that each mistress has slept with the other shepherd) attributed to him in the 1734 GM.
