The allure of the unknown fades into the tawdry reality of a specific representation, once you see it dripping sequins. Abraham's God of Extelligence was far more compelling than a few golden (probably just gold leaf) idols. But when the Renaissance artists started to paint God as a bearded man in the clouds, they opened the way to doubt. The image just wasn't impressive enough. The pictures on radio are always so much better than those on TV.
