MADRID.- The new sculpture by Richard Serra "Equal Parallel/Guernica-Bengasi" can now be seen at the Museo Reina Sofia, where the old library has been specially prepared to house the work of art, which substitutes the one created in 1986, which disappeared in 2006.

The sculpture has been reinstalled in a new atmosphere of the permanent collection of the Reina Sofia after having formed part of the exhibition "Richard Serra Sculpture: Forty Years", at the Museum of Modern Art (MOMA) in New York during the summer of 2007.

This second version of the sculpture - the first disappeared in 2006 and has never been found – has been reinstalled due to an agreement reached between the American artist and the museum, for which Serra authorized the museum to replace the missing work and to install it after the MoMA retrospective dedicated to Serra.

According to the museum, after several meetings with Serra a deal was struck where the sculptor would fabricate the slabs of steel that conform the work of art "Equal-Parallel/Guernica-Bengasi. But, since the pieces were going to be replaced, and not a new acquisition, the author did not receive money.

Also in the new deal struck with Richard Serra it was specified that the formal and technical characteristics of the pieces to be replaced would be identical to the original "Equal-Parallel/Guernica-Bengasi", made in 1986.
