The 19/01/2017 nell’ambito del ciclo di seminari “Visualization of scientific and technical knowledge”, organized by Fanny Kieffer, Isabelle Laboulais, Martial Guédron and Olivier Poncer at the University of Strasbourg, Alexander Neuwahl participated for ArtesMechanicae with a speech entitled “Portraits de machines – Leonardo da Vinci and the engineers of the Renaissance ”. Through an excursus of the first late medieval and Renaissance artists-architects-engineers, a picture has been drawn of the main evolutionary lines of the methods of representation in the field of technology which over the centuries have led to the modern conventions of technical drawing, also taking inspiration from the work of Romano Nanni published in the volume "Leonardo and the mechanical arts" (will ski, 2013).
