This article considers the relevance of the Society for American Archaeology's 2018 “Statement on Collaboration with Responsible and Responsive Stewards of the Past” for imported antiquities (specifically, “classical” ones—that is, from Mediterranean regions). Various practical, legal, and ethical differences between collecting imported versus domestic objects make it difficult to identify “responsive and responsible stewards” of the former. An obstacle to responsible stewardship of privately owned classical collections—and to collaboration between classical archaeologists and collectors—is the 2008 acquisition guidelines issued by the two leading professional organizations in the museum field. I argue that the best home for unprovenienced and poorly provenienced antiquities collections is in university museums, where their complicated object biographies can be fully researched, taught, and displayed.

In the global struggle to protect not-yet-excavated archaeological sites from looting, despite legal strictures, the playing field remains badly tilted against the site guards, customs officials, antiquities police, and prosecutors who lack the financial resources to enforce existing laws. To supplement and give teeth to the strict, but ineffectual, legal regime now in place, economic theory points to a policy solution: a “pollution tax” on antiquities purchased by residents of “market” countries, designed to internalize the social costs of looting so that the industry either takes measures to clean itself up or pays the government to prevent or mitigate the harm the industry causes. Tailored to fall more heavily on antiquities with weaker provenance or extremely high prices, and channeled into an antiquities-protection “superfund” (as was done to clean up toxic chemical sites) or via existing governmental agencies, a Pigovian tax on antiquities could provide a sustainable funding stream for more robust monitoring and enforcement efforts against the illicit market as well as for better site security. Archaeologists and dealers may find the idea of this kind of tax repugnant, but such feelings may be overcome through sustained discussion and negotiation explaining the benefits to both sides of a more licit regulated market.

Indigenous peoples have historically experienced countless losses of cultural relics and material and spiritual treasures as well as the destruction of their sacred cultural sites, a situation that continues to prevail. This desecration of ancestral sites and the pillaging of sacred objects results in the cultural debasement of indigenous peoples, causing a serious threat to their continuing collective existence as distinct societies. Unfortunately, the present international law regime for the protection, repatriation and return of stolen and illegally exported cultural property presents serious deficiencies as regards its ability to reverse this state of affairs and effectively safeguard indigenous peoples' heritage.

Until recently the UK was notorious for its illicit market in unlawfully removed art and antiquities from around the globe. Today the UK marketplace is operating in a very different climate. The UK has recently become a state party to the 1970 UNESCO Convention and is now introducing a package of measures designed to strengthen its treaty obligations, central to which is the creation of a new criminal offence of dishonestly dealing in cultural objects unlawfully removed anywhere in the world. These also include the development of effective tools to aid enforcement and due-diligence. Recent events in Iraq have also forced the UK Government to announce its intention to ratify the 1954 Hague Convention.
