Perspective (from Latin perspicere, to see through) in the graphic arts, such as drawing, is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are drawn:
- Smaller as their distance from the observer increases
- Foreshortened: the size of an object's dimensions along the line of sight are relatively shorter than dimensions across the line of sight

To really get the sense of things going off into the distance as perspective does you need to first learn 1 point perspective. One point is great for distant landscapes and was developed around the 5th century and developed in the Medieval era. Graphical perspective based on mathematics and didn't really mature into the way we know it until the Renaissance. Here all objects above or below the horizon collect to one vanishing point in the distance on the horizon line.
I then taught 3 point perspective but must have accidentally deleted the pics off of my iPhone without noticing before making this blog post:( We drew skyscrapers from a birds eye view and worms eye view. More often I draw a church from worms eye view as it helps show how distorted space becomes at the steeple if your vanishing points are close together. While explaining when you are drawing everything takes your perspective in your world and thus you are the god plus I usually draw a church one my students asked me to put these into god perspective so I called birds eye view angels view and worms eye view the view from praying on your knees. I went one step further and called one heaven and the other hell. Dry yes, but it gave me a ridiculous "literal" chuckle. Dry I know.
