Misericordia is a kinetic installation presented for my "Meisterschüler"(MA) degree exam at the Berlin University of the Arts. The misericordia dagger swings over the water mirror and eventually cuts its surface. A machine installed on the ceiling moves the dagger back and forth. A slight asymmetry in the dagger generates oscilations and variations on the pendulum movement. This type of daggers were used in the middle age to give the coup of grace to wounded soldiers.
