Crowd in the Piazza del Popolo in Rome

In the background of this painting a topographically accurate depiction of the Piazza del Popolo can be seen as it was before 1655 when Bernini transformed the architecture into the Baroque style. It should be noted that the painting is dated 1664, which means that the painting was executed after the architecture of piazza had been transformed. However, the main subject of the painting is not the architecture but the picturesque scene of everyday life in the foreground.
