How to Build a Perspective Veil

The Renaissance was a period of extraordinary artistic and scientific discovery, where artists and thinkers sought to understand and recreate the world with mathematical precision. One of the greatest challenges of the time was capturing realistic depth and proportion on a flat surface — and artists developed ingenious tools to solve this problem.

One of those tools was the Perspective Veil, first described by Leon Battista Alberti in the 15th century. It consists of a grid of threads stretched across a frame. By looking through the grid at a subject, an artist could map the scene square by square onto a corresponding grid on paper, making accurate perspective accessible to anyone.

In this Instructable, I will show you how to build your own perspective veil and use it the same way Renaissance artists did.

1. A piece of cardboard
2. Tape
3. Scissors
4. Pen/Pencil
5. Ruler
6. A toilet paper roll
7. Twine(Any sort of string will work!)
8. Paper(optional)-Used for drawing afterwards

I used TinkerCad to design what I was going to build. This step is optional for you because this is more of a documentation.

I first imported a 20 cm x 25 cm x 0.2 cm frame with 2 cm borders on each side.

I then added strings horizontally and vertically.

I then added two 6 cm x 8 cm triangle stands.

I imported a 6.5 cm x 11 cm x 0.2 cm base with a 11 cm x 0.2 cm x 1.5 cm fin to hold the cylinder up.

I then added a pipe with length of 11 cm and a diameter of 1.6 cm on top.

Cut out a 25 cm x 20 cm piece of cardboard, and then measure 2 cm in from the border and cut out from the inside.

On the all four sides of the frame, poke holes every 4 cm using a pen or pencil. This is so we can put the string through it later!

Thread string in each pair of opposite holes. Leave a little more string than you think you will need. You will end up tying them on the back. For me, a double knot was sufficient.

Cut out two triangles with bases of 6 cm x 8 cm and attach the 8 cm sides to the frame.

Cut out a rectangle piece of cardboard that is 5 cm x 10 and a thin piece of cardboard that is 2 cm x 10 cm. Attach the thin strip of cardboard on the center of the base.

Tape on the toilet paper roll. Your eyepiece is now done!

You place the frame in front of the 3d object you want to draw, and put the eyepiece at a fixed point. You look through the eyepiece and draw what you see in each grid on your paper. That way, transferring 3D objects into 2D becomes easier.
