All of these pieces of art were created around the same time period. Their ideas are all created and based around the structures and buildings of that time period. They contain a variety of moods and settings. They all also seem to be symmetrical and created in mathematic perspective. In One Point Perspective there is a vanishing point with octagonal lines radiating outwards from this point. At the ends of this point, perpendicular lines meet to form shapes. This is a common application to art in the renaissance time period. When viewing these pieces of artwork, you can instantly locate the horizon line and the vanishing point, which are the guidelines to creating one point perspective art.
