Spain's Prado, where you can touch the art - if you're blind
Museum makes copies of works by famous artists use a relief painting technique that adds volume and texture to allow the blind or those with limited vision a chance to create a mental image of a painting by feeling it
Staff at the Prado, Spain's top art museum, usually prevent visitors from touching its priceless treasures.
But recently, with their blessing, Jose Pedro Gonzalez, 56, slowly ran his fingers over a copy of one of 17th century master Diego de Velazquez's most famous paintings, Apollo in the Forge of Vulcan.
His hands ran back and forth over the depiction of the god Apollo wearing a laurel crown, tracing the edges of his garment.
"There are many things that you can discover and that you love discovering," says Gonzalez, who has been blind since he was 14.
The painting is one of six copies of works by masters such as El Greco and Francisco Goya specially created for the Madrid museum's first exhibition for the blind.
They use a relief painting technique that adds volume and texture to allow the blind or those with limited vision a chance to create a mental image of a painting by feeling it.
Water bowls are ready for the accompanying guide dogs, and an audio guide advises the visitors how best to explore the paintings through touch.
"This is a brilliant exhibition. The only way the blind used to have access to paintings was through explanations from another person," says Gonzalez, who has visited the "Touching the Prado" show several times since it opened in January.
Museums in other nations have used the same technique to reproduce works for the blind, but their copies were smaller and only in black-and-white, says the curator of the Prado exhibition, Fernando Perez Suescun.
The copies in the Prado exhibition have the same proportions as the originals but are smaller to allow blind guests to touch and feel their way through the entire surface.
The museum selected works that are representative of its vast collection and whose details could be highlighted by adding volume.
"It is hard for a blind person to build a mental image of what these works are like, so we looked for paintings that provided information but were clear," Suescun says.
The Prado plans to take the paintings on tour to other Spanish cities once its Madrid run ends on October 18.
The exhibition is part of a growing effort by Spanish museums to make their collections accessible to the visually impaired with help from Spain's national organisation for the blind, known as ONCE.
The nearby Reina Sofia modern art museum, home to Pablo Picasso's masterpiece Guernica, allows blind guests to touch some of its sculptures while Madrid's Costume Museum has set up a permanent exhibition of original dresses, including an 18th century gown, that can be felt.
ONCE, which runs a popular daily lottery in Spain that employs more than 20,000 blind or disabled lottery vendors, advises the museums on how to improve visits for the blind.
"All of this helps not only blind people, but also anyone with any type of disability," says Angel Luis Gomez Blazquez, head of ONCE's leisure and sports programmes.
ONCE's museum in Madrid displays 34 models of world landmarks such as the Eiffel Tower, the Taj Mahal and the Kremlin, that the blind can touch. A restorer visits the museum every Monday to repair any damage done to the models.
Blind people sometimes come to touch models of places they are about to visit or of buildings they saw before they lost their vision, says Estrella Cela, a museum guide.
"It can also serve for that, to remember things that you already know," says Cela, 59, who has worked at the museum since shortly after it opened at the end of 1992 and is blind herself.
"Touching, smelling, listening, are very important. As I lack sight I have to complement this with my remaining senses," says Jose Luis Andres, 55, who lost his sight eight years ago, as he feels a dress at Madrid's Costume Museum.
"Your hands teach you a lot."
