Center for Art Collection Ethics

Nearly every week, a news headline announces the latest lawsuit over a valuable work of art. An heir of Holocaust victims sues a museum over a painting stolen by the Nazis. An antiquities-rich country sues a dealer or gallery over objects plundered by profit-seekers. Indigenous peoples claim sacred objects looted by amateur archaeologists and donated to art museums. Often, the objects have been sold multiple times before reaching the current owner, complicating legal and ethical dimensions of the disputes.

In an effort to increase awareness of these issues and promote art provenance (ownership) research training, the University of Denver has established the Center for Art Collection Ethics (ACE) in the College of Arts, Humanities & Social Sciences.

The Washington Principles 20 years later: Some progress but not enough

On November 26-28, 2018, the German Lost Art Foundation hosted a conference in Berlin to assess progress made by the international community in the restitution of Nazi-era art over the past two decades. The conference marked the twentieth anniversary of the 1998 Washington Conference Principles on Nazi-Confiscated Art, a non-binding agreement adopted by 44 countries in the context of a broader international conference on Holocaust-era assets. The principles promote provenance research on works of art confiscated by the Nazis that were not restituted to rightful owners and have ended up in art collections around the world. These nations agreed that “every effort should be made to publicize art that is found to have been confiscated by the Nazis,” and when victims or heirs can or cannot be identified, “steps should be taken expeditiously to reach a just and fair solution.” Governments backing the agreement also would promote the establishment of “national processes to implement these principles.”

The University of California system pursues greater compliance with NAGPRA 

California governor Jerry Brown recently signed into law a measure that requires the University of California system to ensure compliance with the 1990 Native American Graves Protection and Repatriation Act (NAGPRA). The law creates a systemwide repatriation oversight commission that will consult with the State of California Native American Heritage Commission, a nine-member body appointed by the governor. The new measure also provides for two audits to ensure ongoing compliance across the UC system.

Students from several UC campuses lobbied for the bill in Sacramento, citing a need for greater transparency and more consistent adherence to NAGPRA regulations. The challenge of implementation remains, but it is a promising measure that recognizes the importance of Native heritage and the responsibility of Universities to conserve ethically and, when warranted, repatriate.

The Impact of ISIS Art Trafficking

The Syrian government recently put on display in Damascus some 500 objects that had been plundered during the country’s brutal civil war. ISIS has been the worst offender in the destruction of cultural heritage in Iraq and Syria, destroying artifacts and historic sites in territories of the short-lived caliphate, such as the monumental Arch of Triumph in the ancient city of Palmrya. They also beheaded 82-year-old Syrian archeologist Khaled al-Asaad, a world renowned expert who served as the city’s head of antiquities for forty years, after failing to extract information from him on rumored stores of hidden gold.

Thai Repatriation

Thailand claims works from U.S. museums

As France, Germany and Britain grapple with repatriation demands from former colonies and other territories they once controlled, the United States is investigating claims from Thailand. In February 2018, after a year-long probe into missing objects, the Thai Minister of Culture, Vira Rojpojchanarat, called for the return of 23 artifacts from major U.S. museums. The claim widened on November 1, when the Thai government announced it would seek a total of 705 looted artifacts from museums in the United States and Australia. Thailand provided photographs and documents to bolster its claim that the disputed objects were looted from temples and archeological sites. The U.S. Department of Homeland Security is now studying the documents.

The claimed works include two 11th-century stone lintels held by the Asian Art Museum of San Francisco and an 8th-century Buddha statue in the permanent collection of the Metropolitan Museum of Art in New York. Other institutions impacted by the claim are the Norton Simon Museum in Pasadena, holding ten items under investigation, and the Honolulu Museum of Art, which holds fourteen disputed objects, including a bronze prehistoric bell and Buddha statues from the Dvaravati and Ayutthaya eras (6th to 11th and 14th to 18th century CE, respectively).

The Quiet Vulnerability of Museums

In a recent piece in The Conversation, Denver Museum of Nature and Science curator Chip Colwell reflected on the tragic lessons learned from the fire at the National Museum of Brazil. As Colwell points out, we like to think of museums as secure havens for artistic and cultural heritage. The buildings’ architecture often conveys timelessness—think of the neoclassical columns and dome of the U.S. National Gallery of Art.

Yet museums require consistent investment and active stewardship. The Brazil fire shocked us into remembering, as Colwell argues, that “collections are never permanently safe.” What was lost ? An estimated 18 million artifacts. The only recordings of now lost populations indigenous to South America. “ Luzia ,” a 11,500-year-old human skull and the oldest known in the Americas. Traces of local, tribal, and national Brazilian heritage, and a human patrimony common to us all. May those in positions worldwide who oversee the funding of museums recognize the importance of dedicated investment and stewardship.
