This document discusses one-point perspective in Renaissance art. It explains that during the Renaissance, artists became interested in making two-dimensional artwork appear three-dimensional. Artists used mathematics and close observation to develop linear perspective techniques. One-point perspective involves drawing orthogonal lines that converge at a single vanishing point, making distant objects appear smaller to create the illusion of depth on a flat surface. The document provides instructions for how to draw a simple one-point perspective scene using a horizon line and vanishing point.
