“You have just come in, when it appears abruptly astonishing you with the appalling nightmare of a Calvary. It is like the typhoon of an unbridled art which passes by carrying you away”. The altarpiece of Isenheim (1518), today in the Museum of Unterlinden in Colmar, masterpiece of the great painter Mathias Grünewald, in this tale appears and disappears in movement like a loose intermittence of the eye which, blinded, blurs the sight and captures the prey. Fragments of a polyptych syllabizing a theory of grief, and of happiness falling. (Shot on the basis of an anthology of texts edited by Giovanni Reale).
