List of artworks with contested provenance


Throughout the world, there are many works of art that have a contested provenance. This may be due to theft, lost documentation, looting, or just information lost to antiquity. In some cases, just the previous or current ownership of the work is disputed, but in other cases the authenticity of the work itself may be thought to be a forgery. During World War II, Nazis stole many works of art from Jewish families, or looted them from cities in the war.

Cleveland Museum of ArtApollo Sauroktonos by Praxiteles

The Cleveland Museum of Art purchased a bronze sculpture of Apollo Sauroktonos, which some believe to be the only bronze in existence from the original Greek artist Praxiteles. However, the work has an incomplete provenance, and some claim it is a later Roman copy.

Louvre – Bronze Monkeys

Recently there has been debate within the antiques industry regarding a bronze monkey held in the Louvre initially believed to be the work of famous sculptor Giambologna. Following the finding of two other bronze monkeys by British antique dealer Colin Wilson, however, the validity of the monkey held in the Louvre, claimed by 'experts' to be the real work of Giambologna, has been called into question. The Louvre monkey is simply too deep to fit the niche in which it was supposedly situated on the Samson and a Philistine fountain it was originally designed and created for. The quality of the monkey in the Louvre is also up for debate; the form is not lifelike, the fur is not realistic, and the pose does not match the poses of the monkeys in the Uffizi drawing, which is the only evidence for the monkeys being in the niches. Colin Wilson's monkeys, however, do match this drawing, are made of a gunmetal dated to the 16th/17th century, are unrefined, and are of a high lead content, all of which are traits of a work of Giambologna. The debate continues to this day. In July 2008, the Colin Wilson monkeys, along with a newly discovered third, were sold at auction.

Republic of Austria – the equestrian painting of Bellini from the Sarah Lederer Collection

Ernst Lederer, a well known art historian, has been "dazu bewogen" to "donate" this valuable painting to the Republic of Austria in return for an export license for a fragment of the large Lederer collection which was
destroyed at the end of the war by SS troops at Schloss Immendorf or like the textiles and drawings disappeared during 1938–1940. In such a case Austrian courts would refuse to accept any claims for compensation. The famous Klimt Fries in the Lederer collection was, however, not included in the export license, and it took until the 1970s when Chancellor Bruno Kreisky himself started negotiations for the Republic of Austria to buy the Klimt Fries from Lederer.When Erich Lederer had tried to get back the Bellini painting in the 1950s the Austrian Ministry for Education refused.
