Glossary Term: Linear perspective
Perspective is a technique for representing three-dimensional space on a flat surface. Many artists around the world have employed various techniques for portraying depth. However, it wasn't until the Renaissance that artists invented a mathematical system to show depth logically and consistently. The system of linear perspective gave artists a powerful new tool for creating realistic art.

Linear perspective is based on the way the human eye sees the world—objects which are closer appear larger, and more distant objects appear smaller. To create this illusion of space, the artist establishes a vanishing point on the horizon line. Objects are drawn using orthogonal lines which lead to the vanishing point(s). In one-point perspective, the forms are seen face on and are drawn to a single vanishing point. Objects seen at an angle would be drawn with two-point perspective using two vanishing points.
