How To Draw The Pantheon

Example..

Step 1. Before starting work on a building such as the Pantheon, you must first poses an understanding of perspective. Let's start at the very beginning (if you already have a good grasp of how to use perspective to draw buildings, you can skip ahead to step 10). Let's start with using one point perspective to create cubes. Using a ruler and a 2H or harder pencils, very lightly draw the horizon line (blue line) and the vanishing point (red X).

Step 2. Next, draw a few squares floating in various places on the page, but not too close the vanishing point.
