Lib. X.
Lib. X is a scholarly treatise held by the Stiftung Bibliothek Werner Oechslin in Einsiedeln, with no further publication details in the record. Its plates are geometric and mechanical diagrams: a water wheel and mill machinery, lettered triangles, a circle divided into radial spokes, sun-path projections with labelled arcs, and a shaded sectoral diagram with numbered lines. A designer might take from them the clean, labelled line work and the precise geometric construction of circles, angles and radiating lines.
