Three walks yesterday: One in the morning, one at lunchtime, one in the evening.

In the first, the sun blared in from the east, blotting out all color on the Mall. The darkness in this photograph is deceptive. The place was flooded with light. But as I stepped in front of the Capitol, the rising sun seemed to disappear behind the building, and the birds, lively at that time of day, flew in and out of the rays.

It was only when I looked at the photo again today that I noticed the aura that emanates from the Capitol Dome. As if the sun was rising right behind it, as if the city ceased to exist beyond that horizon. Not just the city but all known inhabited places.

What lies beyond is terra incognita. A steep cliff and then nothing. Unknown lands. A blank slate. The future.
