Spanish artist Eduardo Chillida's 16-ton sculpture "Buscando la luz IV" (Looking for the Light IV) sold for a record 4.09 million pounds ($6.32 million) at auction in London, Christie's said.

The corten steel piece was executed in 2001 by Chillida (1924-2002).

The imposing 8-meter (26-foot) sculpture broke the record for a Chillida piece, which had been set at Christie's in 2006 by "Rumor de limites no. VI" (1969), a piece that went for 2.02 million pounds ($3.12 million at the current exchange rate).

The massive sculpture "is a spectacular monolith, standing as a philosophical and conceptual counter-point to the artist's seminal 'El Peine del Viento' (Wind Comb) ... the totemic column extends into the sky, gracefully widening at its apex as if raised in exaltation to the sun. Just as 'El Peine del Viento,' anchored to the rocks and surrounded by the sea, is a tribute to the wind and the water of the artist's beloved San Sebastian, 'Buscando La Luz IV' is an homage to light and to the earth," the auction house said.

The buyer of "Buscando la luz IV" was not identified by Christie's.

"Buscando la luz IV" was exhibited from 2002 to 2004 at the Yorkshire Sculpture Park in northern England. EFE
