The politics of marble consist in its historical significance and its domestic sources. The grandest structures of the ancient European empires, buildings that stand to this day, were monuments of marble. Marble "says" permanence and empire; marble is good for national self-esteem. The statues, halls and pyramids of Washington are conscious echoes of Greek, Roman and European predecessors. And each state is proud to have its specialty stone represented in Washington. These columns at the Jefferson Memorial are made of Vermont marble while the floors consist of marble from Tennessee, all of it seated on a foundation of Georgia granite.
