Arco Lamp
About the Design

It was a humble street light that inspired Achille Castiglioni (1918–2002) and his brother Pier Giacomo Castiglioni (1913–68) to design their Arco lamp. The two men, along with their eldest brother, Livio, were the sons of prominent Milanese sculptor Giannino Castiglioni, and all became trained architects. Achille graduated from the acclaimed Polytechnic University of Milan in 1944 and joined Pier Giacomo and Livio in the design studio they'd opened with Luigi Caccia Dominioni. With large architectural assignments hard to come by, the Castiglionis focused on small-scale projects. At the core of their design philosophy was problem-solving, creating objects that fulfilled consumer needs. Their motto was: “Start from scratch, stick to common sense, know your goals and means.”

With functionality a primary concern, the Castiglionis produced pieces inspired by the “readymades” of artist Marcel Duchamp. The Arco lamp was born out of a desire to create a fixture that illuminated like pendant lighting but didn’t require drilling into the ceiling and that could be moved as its owner’s interior evolved.

The initial Arco lamp, designed in 1962, had a marble base (weighing 110 pounds), a chrome ball shade and a long curved steel arm that enabled light to be projected from nearly eight feet up, as if from a chandelier hung overhead. In another ingenious touch, the Castiglionis drilled a hole in the marble base through which a broomstick could be guided to serve as a handle so that two people could move it.

The same practicality is evident in the other famed lighting pieces — including the Snoopy and Taccia table lamps — that Achille and Pier Giacomo designed for FLOS. The brothers began their relationship with the Italian lighting company in 1960, and it continues to make their signature pieces today.

Vintage Pier Giacomo Achille Castiglioni - Flos 'Arco' Marble & Steel Floor Lamp
By Flos, Pier Giacomo Castiglioni, Achille & Pier Giacomo Castiglioni, Achille Castiglioni
Located in Philadelphia, PA
The Carrera marble base has very slight, barely noticeable yellowing. Telescoping arm shows signs of light oxidation, but operates well. The polished and coated/sealed aluminum shade shows light scuffs and scratches. Wiring is original. Lamp works as it should. In very good shape for being ~70 years old. This lamp is not signed. I'm guessing the manufacturer's sticker label dried out and fell off. Typically, the labels were adhered to the ceramic bulb socket, which would heat up and dry out the glue. Also notice the small hole perforated diffuser, on which the polished aluminum shade rests and pivots, is unusual. Many lamps have the larger holes found on the more recently made examples. The small holes diffuser is found on the vintage Flos Arco...

The idea of the readymade didn’t just upend the art world, it also provoked a wave of invention in design. This provocative spirit is alive and well in the Toio floor lamp, which sees an integration of automotive parts as well as everyday recreational gear. Along with their eldest brother, Livio, Pier Giacomo (1913–68) and Achille (1918–2002) Castiglioni were born in Milan and for a time, the three worked together in their own firm as architects and designers.
