The Wolf Den is set in CE 74, five years before the eruption of Vesuvius buried Pompeii beneath volcanic ash. Harper draws on archaeological evidence from the city’s Lupanar, the only purpose-built brothel identified among Pompeii’s excavated ruins, to reconstruct the lives of enslaved sex workers. The Lupanar, situated at the junction of two narrow streets, contained 10 small stone-bedded cells decorated with sexually explicit frescoes, artifacts now housed in the Naples National Archaeological Museum. Historian Thomas McGinn has estimated that Pompeii housed as many as 35 locations used for commercial sex, illustrating how deeply the trade was woven into the city’s economic fabric (McGinn, Thomas. The Economy of Prostitution in the Roman World, Cambridge University Press, 2004).

Amara enters slavery through a path consistent with documented Roman practices. Freeborn individuals in the ancient world could be legally enslaved through debt, parental sale, or capture by pirates. Amara’s mother sells her after her father’s death, and Amara later reflects that her mother acted “to ensure [her] survival” (60). This trajectory mirrors cases documented by historian Keith Bradley, who has noted that impoverished families frequently surrendered children to creditors or traders, a practice common enough to generate sustained legal debate in Rome (Bradley, Keith. Slavery and Society at Rome, Cambridge University Press, 1994).

The novel’s portrayal of the Wolf Den’s physical environment corresponds closely to the archaeological record. The cramped, windowless cells, stone sleeping platforms, explicit wall paintings, and phallic oil lamps all reflect artifacts recovered from the Lupanar site. Amara describes these lamps as “modelled in the shape of a penis, flames flickering from the tip” (20), a detail drawn directly from excavated objects. By grounding her narrative in these material remains, often treated by modern visitors as titillating curiosities, Harper reframes them as evidence of the systematic dehumanization that enslaved women endured, lending historical weight to the novel’s exploration of agency within a coercive system.
