design Achille Castiglioni, 1998

“My father was a very, very good Diabolo player,” says Giovanna Castiglioni, daughter of legendary Italian designer Achille Castiglioni. This diabolo game, derived from a Chinese yo-yo, involves juggling a projectile in the shape of double inverted cones with a string stretched between two sticks.

The Diabolo pendant is Achille Castiglioni's latest creation for Flos. Composed of two inverted cones connected by the power cord, the suspension is adjustable in height thanks to a pulley system hidden in the upper cone: the height, the brightness and the lighting zone can thus be adjusted according to the needs. 

In addition to the classic white, Flos reissues the Diabolo pendant light in beaver brown and cherry red finishes with white interiors, colours inspired by the vases designed by Achille and Pier Castiglioni for Cedit in 1968.

Achille & Pier Giacomo Castiglioni

Italian architects and designers Achille Castiglioni (1918-2002) and Pier Giacomo Castiglioni (1913-1968) are among the greatest names in modern Italian design. Their father was a notable architect, Giannino Castiglioni, and their brother, Livio Castiglioni, also became an architect and designer. Achille and Pier Giacomo both studied architecture at Politecnico di Milano and then worked there as teachers. Their collaboration has been productive and innovative, and the designs are often radical and humorous.

Similar to the designers of the first half of the 20th century, the Castiglioni brothers derive the beauty of an object from its function. Purity of lines, simple components, quality of materials, aesthetics intervenes to support the function.
