Sand…those little rocks on the beach. Sand…in the 19th century, it was just one more slang term for testicular fortitude. Because you can never have too many ways to say it! Rocks, gravel, sand, guts, nuts…he’s got some set of balls on him! But back in the day, they used to say: “He’s got sand!”
Gary Greenberg, a biomedical researcher from University College London, has recently published A Grain of Sand, a book of close-up photographs of sand. He sees the big picture in the little picture. He’s not the only one. Way back in the 18th century, proto-homosexual poet William Blake wrote:
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
