Sopra le Macchine-a-vapore
An 1817 Italian treatise on steam engines by Luigi Serristori, held by the Eisenbibliothek Schlatt, written for engineers and mechanics of its day. Its engraved plates show a ship plan with paddle wheels, a cross-section of the vessel, and a wheel drawing with spokes and rim fittings, all in fine black line on pale paper, with a separate red wax seal from an unrelated medieval document that a designer might treat as a stamp-like emblem for period engineering graphics.
