## 1970 Perspective Grids

Four large paintings (72"x 108") of possible two point perspective systems.
The two-point perspective system used in this earliest painting (1969) is the one
commonly used to describe objects in our everyday, walk-around space. The points to
which all the lines receed lay just outsideof the framing edges of the painting.
This is a system, long accepted as one that describes our everyday flat, singular space.

In this second painting (also 72"x 108") the linear perspective system has been changed by closing the
space. To make this happen, all the lines in the upper half receed to points on either side of the
painting that are located below the central horizon line(not shown in the painting). And the
lines in the bottom half of the painting go to points located above center. In other words,
there are four perspective points that create this closed perspective space. This is the space
that we would inhabit if space were bounded, such that in a finite time one would reach the
horizon, the limits of this bell jar space.

In this third painting the recessional points remain outside the painting, but the regular
counting off of the grid lines happens in the vertical center line, making a grid space
that contracts and expands.

In this fourth vertical painting the two systems of space making are brought together.
