 A stationery camera looks across the boulevard at a diagonal toward one corner of Lyon s Cordeliers  Square. It s a long shot, with a great deal of depth of focus. We can see the sky and fronts of four buildings, each four or five stories tall. It s a busy thoroughfare, with pedestrians walking in front of the buildings and crossing the boulevard between horse-drawn vehicles. A double-decker bus passes in front of us, pulled by two horses. Various tradesmen pass on wagons. One van passes.
