Through his art, Adolf Wölfli, once a psychiatric patient at the Waldau Asylum, created a universe that defies imagination. On a journey through the Emmental and the visual worlds of this exceptional Swiss artist, Ueli Jäggeli and Daniel Baumann follow in the footsteps of a man, who, in his works, transformed himself into «Allgebrathor»: an all-powerful giant, inventor, military commander, and steamship captain.
