“All the rays which convey the images of objects through the air are straight lines. Hence, if the images of very large bodies have to pass through very small holes, and beyond these holes recover their large size, the lines must necessarily intersect.”

— Leonardo Da Vinci

“All objects transmit their image to the eye in pyramids, and the nearer to the eye these pyramids are intersected the smaller will the image appear of the objects which cause them.”

“In that year [Einstein] had roughly equal numbers of large and small cats. Therefore, quite logically, he cut two holes in each door: a large one for the large cats, and a small one for the small cats. It made perfect sense. … A hole should have a meaningful existence, and the small cats might be offended if a personalized nothing was not prepared for them.”

“Since the violet rays through the objective of the theodolite telescope have a shorter focal length than the red rays, it is evident why the eye-piece must be displaced in order to see plainly the lines in the different colors.”

“All bodies together, and each by itself, give off to the surrounding air an infinite number of images which are all-pervading and each complete, each conveying the nature, colour and form of the body which produces it.”

The Notebooks of Leonardo da Vinci (1883), II Linear Perspective

“All the absurdity and hope are the stimulants to create. You make art to find a little hole to go on. You go through the whole to find the world again, and the absurdity is that still, somehow it is the same... Hopelessness and hope are the same. It's a very thin line you don't see any more. I don't believe in that line between hopelessness and hope today.”

“The first hole made through a piece of stone is a revelation. The hole connects one side to the other, making it immediately more three-dimensional. A hole can itself have as much shape-meaning as a solid mass. Sculpture in air is possible, where the stone contains only the hole, which is the intended and considered form. The mystery of the hole – the mysterious fascination of caves in hill sides and cliffs.”

Henry Moore (1898–1986) English artist

“If you transmit the rays of the sun through a hole in the shape of a star you will see a beautiful effect of perspective in the spot where the sun's rays fall.”

“No small hole can so modify the convergence of rays of light as to prevent, at a long distance, the transmission of the true form of the luminous body causing them.”
