Although there is no image shown for this question, Pietro Perigino is an artist that is known for his peculiar depiction of space behind his painting. His works were famous before the arrival of Michelangelo's painting of the Sistine Chapel.
The paintings actually had presented great Linear perspective that redefined the idea of space in the paintings. He played around with a simple technique that adapts well with the foreground, middle ground and background.
Answer:
Perugino used two types of perspective: the one-point linear perspective, and the atmospheric perspective.
Explanation:
The painting analyzed here is the Christ Giving the Keys of the Kingdom to St. Peter or simply Delivery of the Keys. To create this amazing fresco, Perugino used two kinds of perspectives to promote the effect of depth. The first is the one-point linear perspective, which uses a group of lines that find themselves on the center of the canvas (the vanishing point). In this case, the vanishing point is the chapel in the center. To create the atmospherical feeling, and the correct use of light, Perugino used the atmospheric perspective, with the distant objects diminish in appearance through a bluish-gray haze, as seen in the mountains in this case.
