We adore this ceiling light from designer Alessandro Mendini. He created it for Venini in 1990 and had it hanging above his own kitchen table at home in Milan. It is remarkable not just for its luminous colours but also as a beautifully crafted piece of Italian blown glass. The artist's proof of this wonderful Archernar lamp goes up for auction this month at Piasa in Paris. Mendini trained as an architect and worked as a journalist, notably as editor at Domus after Gio Ponti, but he is best known as one of the Memphis group alongside Branzi and Ettore Sottsass who took Italian design into pop in the 1980s. His output is incredibly diverse; from reinventing the image of Alessi, building a tower in Hiroshima to projects at Hermes, Cappelini and Swatch.
