Episode notes
Don't Force Ancient Slavery Into Marxist Models
- Avoid reducing ancient slavery to deterministic Marxist stages; compare models to diverse evidence instead.
- Harper argues markets and labor mobility existed in Rome, so scholars should test models against papyri, inscriptions, and economic data.
Conquest Was One Of Several Slave Sources
- Military conquest supplied many Roman slaves but was not the sole nor always dominant source of slave supply.
- Harper stresses natural reproduction, trade imports, and abduction as major, often underappreciated components of slave supply.
Freedmen Visibility Distorts Manumission Rates
- Manumission was common in urban and skilled contexts but far less so in rural sectors; freedmen visibility skews impressions.
- Harper warns epigraphic records overrepresent urban freedmen, while many rural slaves likely remained unfreed.
