Considering Roman art as a cumulative process could help resolve a small iconographical problem. Cubiculum N in the burial hypogeum under the Via Dino Compagni in Rome (c.350–75 ce) features a series of figure scenes referencing the exploits of the mythological hero Hercules. One of these scenes, presently entitled Hercules Slaying an Unknown Enemy, has no direct equivalent in extant Roman art and so has proved difficult to identify. This article suggests that Hercules’ battle with Cacus is most likely the incident referred to here. This is because Antonine medallions and coins, and third-century Roman sarcophagi, use imagery associated with the Cacus story that collectively could have contributed to the design of the Unknown Enemy panel. Further, identifying the defeated enemy as Cacus fits in with, and indeed helps to clarify, programmatic themes and associations already established in the other figure scenes in this funerary chamber.

The antiquities trade is the subject of contentious debate. The anti-trade position stems from a long unquestioned stance within academia that private ownership of antiquities inherently results in archaeological site destruction and the loss of valuable data. However, there is little data to support this notion. It also ignores the enormous contributions to our shared knowledge of the past that have been made through art collecting and museum acquisitions. The narrative that the destruction of ancient sites is directly tied to Western demand for ancient art is overly simplistic. Despite the ongoing destruction in the Middle East and North African region, virtually no artifacts from there have entered the Western trade in recent years. Opportunistic treasure hunting by desperate locals and intentional destruction of ancient objects for religious reasons cannot be curtailed by increased legislation in Western nations. Fetishizing mundane ubiquitous antiquities as sacrosanct objects of great national importance that must be retained within modern borders in a globalized world and demanding criminalization of the legitimate international art trade are counterproductive. In many archaeologically rich countries, antiquities are regarded as items to sell to foreigners at best or sacrilegious objects to be destroyed at worst. The free trade in cultural objects is itself an institution that needs to be protected. An open legitimate trade in antiquities is now more than ever necessary to ensure the preservation and dissemination of worldwide cultural property.
