[D[as] puechle[n] d[er] fiale[n] gerechtikait]
A 1486 German treatise by Matthäus Roritzer, printed in Regensburg, explaining how to draw pinnacles (fialen) and Gothic architectural geometry for builders and masons. The four pictures are geometric construction diagrams of nested squares, diagonals, lettered corner points and curved arcs that show how a Gothic ornament was laid out step by step from a plan.
