This window started out as a small thing from about 1930, maybe later. The brief was to remake it into a much larger window for beside the front door. I decided to address the task as if I was in the 1260s.

At my patron’s home, I measured the window itself with two sticks, which I cut to length. These, and the old window, became my measuring system for the project. I did not use a calibrated ruler, because they don’t work very well and are not period-appropriate. Materialization of the measurement system prevents all form of cumulative error in the numbers, because I don’t use numbers.

When I rebuilt it, I laid out a frame using a set square. I measured its dimensions physically, using the sticks. I then rebuilt the cleaned old window in the middle, which determined the width of the border. Once the border was in, the last task was to find the middle of the remaining space, which I did by folding a scrap of paper.

For the design itself, I used typical tripartite thinking (although vertically). The wings, at top and bottom, are double chip, for privacy. The central field has also been replaced with textured glass, for privacy. This window shows no through image at any distance.

It’s my Time Traveller. Made in 1935, restored in 1895 style in 1265, in 2026.
