Based on your understanding of linear perspective from the reading (pages 74-77) and from the videos, identify which of the following is considered one-point linear perspective, two-point linear perspective, or lacking linear perspective. Use each classification only once per artwork, and for each, explain your classification using the terms, "horizon line" "vanishing point" and "orthogonal line" in your answers. When was linear perspective developed by Brunelleschi?
