"Pio Manzù had the original idea for Parentiesi. He thought up a fixed vertical boom and a cylindrical box with a slot for the light, which went up and down: you stopped it with a screw. He replaced the boom with a metal chord that, when bent creates friction and enables the lamp to be in position without requiring any screws"
Achille Castiglioni.
