Sophocles

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

I came to feel very, very sentimental about those sets, which is ludicrous, because they represent everything which is transitory and insubstantial. It's absurd that one should feel sentimental about timber and canvas.
