Castelli e ponti
Castelli e ponti is an 1743 Italian engineering treatise by Niccola Zabaglia, with plates attributed to Domenico Fontana, covering scaffolding, cranes and machines for architecture and building works. The engravings show the framed timber towers and lifting structures used to raise and move heavy stone, including the obelisk erection, drawn in plan and elevation with labelled captions. A designer could take from them the clean linear diagrammatic style and the way dense timber framing reads as pattern and structure.
