Market (Verziere Market)

The
  perspective centre of the image is the Redeemer’s column in the middle of
  Verziere market in Milan, and the rigorously front-facing framing allows the
  whole scene, showing trade and commercial activities, to be organised in
  parallel planes. The
  importance of this painting lies in its being an exemplary testimony of the
  collaboration of several artists, according to a practice usual between the
  seventeenth and eighteenth centuries for the genre of the "view".  The final result here is
  the sum of work by painters specialising in still life, backdrops and
  architectural figures. The identity of these collaborators is still unknown
  today, but Magnasco’s hand is certainly recognisable in the figures animating
  the middle ground.
