During the Renaissance, the five senses were understood to form a hierarchical system from the highest sense of vision down to touch. Vision was correlated to fire and light, hearing to air, smell to vapour, taste to water, and touch to earth.
Perhaps the human fascination with fire stems from the totality of its sensory stimulation. The fire gives a flickering and glowing light, ever moving, ever changing. It crackles and hisses and fills the room with the smells of smoke and wood and perhaps even food. It penetrates us with its warmth. Every sense is stimulated and all of their associated modes of perception, such as memory and an awareness of time, are also brought into play, focused on the one experience of the fire. Together they create such an intense feeling of reality, of the "here and nowness" of the moment, that the fire becomes completely captivating.
Normally after the design was built, you would find places for the art to be located and then you would go out and select the artist that you wanted. That is historically, the traditional way to go.
But this time, someone else was calling the shots. A planning official, basically, who comes along and says, “We want you guys to work with an artist.” And the architects are like, “Sure of course.” But then the official goes—“No, you don’t quite understand. We want you to use an artist as a co-equal member of the design team.” That is, the artists are going to have just as much control as the architects. It was really unheard of.
