Blue is the one mystical color. Everybody knows this. And that is why this photo seems like an illustration for the passage I have just read John Banville's early novel, Birchwood –
Listen, listen, if I know my world, which is doubtful, but if I do, I know it is chaotic, mean and vicious, with laws cast in the wrong moulds, a fair conception gone awry, in short an awful place, and yet, and yet a place capable of glory in those rare moments when a little light breaks forth, and something is not explained, not forgiven, but merely illuminated.
