Manuel d'artillerie à l'usage des officiers d'artillerie de la république helvétique
A military artillery manual published in 1836 by Orell Fussli in Zurich, prepared for officers of the Helvetic Republic's artillery and attributed to Napoleon. The pictures are fold-out engraved plates of technical drawings: plan and elevation views of carriages, gun parts, timber frames and bridge or battery construction with lettered reference keys. A designer could draw on their precise line-diagram style, dense lettered callouts, and the measured geometry of plan and profile views.
