She needed no time to choose her words. "Do you know how old art is, Senator?"

"As old as man, I suppose. In fact, it may be part of the definition."

That's the age of the oldest surviving artwork, the cave paintings at Lascaux. Doubtless the cave-painters sang, and danced, and even told stories--but these arts left no record more durable than the memory of a man.

Dancers only learned in the last few centuries how to leave even the most rudimentary record of their art.
