Seen a thousand times - a thousand times nothing happened?

What you always want­ed to know about art (his­to­ry)…: What makes a work of art a mas­ter­piece? Why do peo­ple have them­selves paint­ed? How do artists’ self-por­traits dif­fer from por­traits of oth­er peo­ple? For what rea­sons were artists like Ver­meer or Frans Hals redis­cov­ered in the 19th cen­tu­ry, espe­cial­ly in France? What do stu­dio pic­tures tell us about the work­shop prac­tices of artists? Which artist rival­ries can we trace? In which his­tor­i­cal and social cir­cum­stances were epoch-mak­ing works cre­at­ed? Based on these and many oth­er ques­tions, I orga­nize lec­tures — also online — or guid­ed tours in muse­ums accord­ing to your wish­es and interests.
