Theatrum pontificiale, oder, Schau-Platz der Brücken und Brücken-Baues ...
Theatrum pontificiale is a 1726 Leipzig treatise on bridges and bridge building by the engineer Jacob Leupold, written for builders and engineers. Its plates show timber and stone bridge frames in elevation and section, with trusses, piers, centering and pile foundations drawn in fine line engraving. A designer could draw on the clear structural geometry, the repeated lattice of braces and the layered perspective views of arches and framing.
