The Giogali lamp (Compasso d’Oro mention in 1969) introduced a new concept in the use of glass: a modular lighting system based on a single hand-crafted crystal element (a type of hook) that can be repeated indefinitely to give life to structures that appear like cascades of light. The hook is the basic module that constitutes the entire architecture of the Giogali system (name that derives from the Venetian “giongher”, or the strap used in the countryside to tie the cart to the yoke), Mangiarotti’s modern interpretation of the Venetian chandelier.
