This is perhaps one of the most beautiful engravings found in the military textbook by Johann Choura, Lehrbuch der Geometralzeichnens fuer id K.K. Militar-Realschulen, which is a work printed in Vienna in 1879. Its actually from the second volume, which is Darstellende Geometrie, a course on applied geometry for the engineering student in a military-minded advanced school. It is not-so-simple and a lovely work of techArt.
