Artists like Giotto and the trecento had begun to conduct studies on perspective. Giotto needed to represent spatial relationships and volume to create a framework for the figures and objects of his narrative paintings giving them a more convincing as representations of reality.The importance lies in the dynamic relationship between the subject and the object being seen or observed. Filippo Brunelleschi became the discoverer of linear perspective; this is a method to mimic the measurable space on a flat surface.
The contemporary artist Alex Grey uses these principles as a basis for their works. He studied art at Ohio, and in Harvard Medical School was working in the Anatomy department studying the body and preparing cadavers for dissection and for doing medical illustration.
With these details apparently objects are placed in three dimensional spaces, which pushed up the surface of the painting forward where is the observer, and in turn extends backwards where there is an imaginary spatial depth.
Brunelleschi's visual field was perfectly framed by the doorway, perhaps to use that way the door frame and create a grid in which each of its four sides indicating reference points located at equal distance from each other.
Brunelleschi also used polished silver for enhancing the optical illusion sky forcing the viewer to see the Baptistery painting since the location of the artist envisioned when the actual building. While Alex Grey highlights the vanishing point as representing spiritual and basically to attract the attention of the viewer. The image is thus transformed into a window where we see an artificial reality created but data based on actual experience, by appropriate scenery.
Brunelleschi's Legacy, to contemporary and Renaissance artists, was his vision of transform flat images and their discovery in the ideation of imaginary spaces.
