Filippo Brunelleschi1377–1446
One-point perspective, c. 1415
Florentine architect and engineer, builder of the dome of Florence Cathedral, who around 1415 showed with a painted panel and a mirror how to draw a scene in exact one-point perspective.
Vanishing Corridor
Frames receding to a single point, each one the same size as the last and none of them the same on the page.
About this pattern
One-point perspective · Brunelleschi's construction, c. 1415
The whole of one-point perspective is one division: a thing twice as far away is drawn half as big. Space the frames so that each is a fixed fraction of the one before and the corridor becomes even, because the eye reads constant ratio as constant distance. Set the frames moving and they fall inward at a rate that never changes, which is why the loop has no seam in it: the sequence one step on is the sequence it started as.
