In 1977/78, Hans Erni created the monumental mural "Panta rhei" (Everything flows!), in which he assembled the figures of thinkers and scientists who, in his opinion, had given European intellectual history a new turn.
The leporello identifies those portrayed, provides brief biographies and thus reveals the significance of this important work by Hans Erni.
In German, French and English, with a colour overall view of the mural and numerous black-and-white photographs.
