A collection of torture devices used in the 16th and 17th centuries will be sold in New York City with some of the proceeds going to charities campaigning for a ban on torture.

Arlan Ettinger, president of Guernsey's Auctions, said 252 devices, hundreds of torture engravings and a library of rare books devoted to torture would either be sold as a collection or auctioned separately at a later date. The firm estimates the collection could fetch several million euro.

"It's almost what's your pleasure, what part of the body would you like to hurt, which is a terrible thing to say," Mr Ettinger said of the devices. "As brutal as these things are, it's history and if these items get dispersed that would be gone."

The collections includes items like an arm clamp with spikes, a chair with spikes, heavy iron masks, and a metal mitten that could be made red hot in a fire and then put on someone's hand. He said the collection was exhibited in Britain and the US in the late 19th century. It was eventually bought by a Norwegian Holocaust survivor living in the US in the 1950s and is now being sold by heirs.

"These are curious but brutal devices all designed for the purpose of hurting people in specific ways," added Mr Ettinger. "We had to think twice before we would want to represent a collection like this."
