Italian Murano Glass 'Giogali' Rectangular Chandelier by Angelo Mangiarotti for Vistosi, 1960s

An Italian Murano glass 'Giogali' rectangular chandelier designed by Angelo Mangiarotti for Vistosi in the 1960s, composed of over two hundred interlocking glass elements that transform a simple geometric framework into a cascade of light.

The chandelier is built around a long rectangular metal structure, from which individual clear glass links are suspended in overlapping rows. Each element takes the form of an irregular, softly triangular loop, with rounded corners and a substantial, almost fluid profile. As the links descend, they gradually taper toward the center, creating a gently curved underside.

The brilliance of the 'Giogali' design lies in its modular construction. Rather than relying on a conventional arrangement of glass drops or decorative prisms, Mangiarotti developed a single interlocking glass element that could be repeated and assembled into a variety of configurations. Introduced in 1967, the system allowed individual glass links to connect directly with one another, creating larger compositions without requiring a separate metal attachment for every piece. The result is both technically inventive and visually expressive, with the glass itself becoming the structure of the chandelier.

Up close, the individual links reveal subtle irregularities within the clear glass. Fine bubbles, elongated striations, and slight variations in thickness give each element its own character, catching and refracting light differently as it moves through the densely layered composition. The links overlap at varying angles, producing an intricate network of reflections and shadows that makes the chandelier appear almost woven from glass.

Above the cascading elements, a series of exposed bulbs is positioned within the rectangular framework, illuminating the glass from within. When lit, the individual loops become increasingly luminous, their rounded edges catching concentrated highlights while the overlapping surfaces scatter light throughout the fixture. Even unlit, the chandelier maintains a strong presence, its transparency allowing the surrounding architecture to remain partially visible through the layers of glass.

Mangiarotti's approach to the 'Giogali' series reflects his broader philosophy as an architect and designer, in which material, structure, and function were inseparable. Rather than applying decoration to a finished object, he developed a system in which the method of construction generated the decorative effect. This principle became central to some of his most celebrated work, and the 'Giogali' remains an enduring example of his ability to bring architectural thinking into the design of everyday objects.

About Angelo Mangiarotti
Angelo Mangiarotti (1921–2012) was an influential Italian architect, sculptor, and designer celebrated for his rigorous, innovative approach to materials, form, and construction. Born in Milan, he graduated from the Politecnico di Milano in 1948 before moving to the United States in 1953, where he taught at the Illinois Institute of Technology in Chicago and developed relationships with influential figures including Frank Lloyd Wright, Walter Gropius, Ludwig Mies van der Rohe, and Konrad Wachsmann.

Returning to Milan in 1955, he established an architectural practice with Bruno Morassutti, producing industrial, residential, and cultural projects until their partnership ended in 1960. Alongside architecture, Mangiarotti developed a distinguished body of furniture, lighting, sculpture, and objects, distinguished by his masterful treatment of materials such as marble, wood, and glass.

His celebrated designs include the Giogali glass-link lighting series for Vistosi, the Incas Table, and numerous works produced by leading manufacturers including Artemide, Bernini, Cappellini, Knoll, and Skipper. A recipient of numerous honors, including the 1994 Career Compasso d’Oro, Mangiarotti’s work has been exhibited internationally at institutions including the Centre Pompidou, Triennale Design Museum, and Gallery MA Tokyo. He died in Milan in 2012, leaving a lasting legacy as one of Italy’s most inventive postwar designers.
