Abstract
The development of art historiography in the 19th century was greatly aided by the invention of photography. Little by little, masterpieces of painting, sculpture and architecture were photographed in major public collections and on monumental sites. The teaching of art history benefited from this documentation, thanks to the light projections which, from the 1890s onwards, accompanied it first in Germany, then in other European countries, changing the attitudes of both speaker and audience, and redefining certain orientations of the discipline.
Roland Recht devotes his closing lecture to light projections, which have been used for over a century in all art and archaeology lectures. This lesson is supplemented by a text written in 2020, in which the author retraces his career as a researcher with an insatiable curiosity.
