Serendipitous light on a September afternoon--a rainbow arcing over the Eiffel Tower and ending at the gold dome of L'Église des Invalides in central Paris. (Under that dome, emperor worship continues--Napoléon I lies buried in a crypt in the church's floor; to see it you must bow your head.) I had only been in Paris a few days when I went around the corner from where I was staying to buy a few groceries one rainy afternoon. As I walked back, though, I caught a glimpse of the clearing sky in between the buildings--a glimpse of the rainbow. I ran up the six flights of stairs with my shopping bags and then flung open my window just in time to get this view: 'my' Paris.
