by iconographer Matthew Garrett:
"... It seems to me that this is precisely why icons are important. One could easily assume that icons are a way of making the invisible visible. But this is not accurate. Icons are allowable, and in fact necessary, precisely because they make the visible visible. In a sense, they operate in much the same way as a microscope or a telescope does. One would be wrong to suggest that a very small cell or a very distant planet was invisible. They are fully visible, they are every bit as real as the things that we see with the naked unassisted eye, but they cannot be perceived without assistance. Icons help us to see what is visible, but not always perceived."
