Zweyter Band.
The record gives only a volume title, Zweyter Band, from a German-language book held by the Werner Oechslin library, so its kind and date are unclear; the four geometric and construction diagrams suggest an early treatise on geometry or building. Its pictures are plain line drawings on cream paper: a diamond divided into quarters, a circle construction with lettered points, a stepped diagonal, and a framed ladder-like grid of timbers, offering a designer clean schematic structures and lettered line work.
