Leonardo da Vinci als Ingenieur and Philosoph : ein Beitrag zur Geschichte der Technik und der induktiven Wissenschaften
A German-language study of Leonardo da Vinci as engineer and philosopher, written by Hermann Grothe and published in Berlin by Nicolaische in 1874 for readers of technical and scientific history. The 44 figures are small line redrawings of Leonardo's machine sketches — geared shafts, screws and clamps, bearings, hoists, vaned impellers and water channels — numbered as text figures, useful as spare mechanical diagrams or sketch-like schematic motifs.
