I love Flanders and Swann, and no one I know has heard of them: "if the Great(?) hadn't intended us to eat people, he wouldn't have made them of meat!"

And I do mean to learn to play "Have Some Madiera, M'Dear!"

I saw a speculative documentary on the idea of bringing the quarried stones by boat. Ancient boats are an interesting subject, since people have been 'messing about in boats' pretty much since they learned how to chip wood with stone tools. Not many truly ancient boats survive, but I recall they found a very old example in a peat bog a couple years ago.
