De gli avtomati, ouero, Machine se moventi, libri duo
A 1589 Venetian edition of Hero of Alexandria's treatise on self-moving machines, translated into Italian by Bernardino Baldi, printed by Girolamo Porro for a scholarly readership of engineers and mechanics. The pictures are precise engraved plans of pulleys, drums, cords and gear-like mechanisms drawn in clean outline with hatched cross-sections, giving a designer a clear model of early mechanical diagramming and a source for line-based technical schematics.
