For this series Schrofer used a monocase, monospace script drawn in a 3 × 9 grid designspace. He systematically varied the ratios of the vertical and horizontal stroke weights to the respective dimensions of the counters to create glyphs of different proportions.
I built a variable font with two bidirectional axes, one for each of these ratios, to recreate and analyze Schrofer’s designs and covers. Default values of 0 set the ratio of strokes:counters 1:1. Positive axis values increase the relative size of the strokes; negative values, the size of the counters. The axes max out at ratios of 10:1 and 1:10. The diagram highlights the glyph where both ratios are 1:1.
