This is the first ever photograph of a human being, taken in either 1838 or 1839 in Paris, on the Boulevard de Temple:
It was a 10-minute exposure, so although the road looks almost entirely empty it was actually a bustling scene - it's just the traffic was moving too quickly to be captured. However, in the lower left-centre of the picture are two small figures: a man getting his shoe shined. He and the shoe shiner remained in place long enough to be captured.
There is something faintly disturbing about those two figures caught in time. Alone of all the many people who were travelling along the Boulevard de Temple in those 10 minutes - hundreds, perhaps thousands - only they have travelled down to us through the 175 years or so since the picture was taken. And by pure accident. They remind me of insects trapped in amber and preserved by happenstance for all of time.
If I was currently running an Unknown Armies or Call of Cthulu game, this photograph would feature in it. Who were these men, and is their apparently coincidental capture on film actually of cosmic significance?
