Discussion Ideas
- Researchers recently analyzed skeletons from two ancient Roman necropolises. How do they know these skeletons were not native to Rome?
- Researchers analyzed strontium, oxygen, and carbon isotopes in the skeletons’ tooth enamel for clues into the food and water they consumed. Click here to learn more about how archaeologists study tooth enamel for clues about ancient life.
- Strontium isotopes reveal altitude. Old mountains, like the Alps, show higher levels of these isotopes than younger mountains, like active volcanoes.
- Oxygen isotopes indicate the source of water human beings drank from when they were growing up. A local isotope range for ancient Rome is difficult to estimate, the authors say, in part because Romans often consumed and irrigated with water from a variety of sources: local rainwater, river water, groundwater, and water transported from far away through sophisticated aqueducts.
- Carbon isotopes help indicate a person’s diet. Researchers say the carbon isotopes in the ancient Roman skeletons hint a “diet of acculturation.” In other words, once they were in Rome, immigrants ate like Romans: grains, beans, meat, and fish. (Archaeologists can even determine Roman neighborhoods by the grains residents consumed—wheat was popular in one area, millet in another.)

- Why is the new research not entirely surprising?
- Migration in ancient Rome is very well documented “within the bounds of history, material culture, and epigraphy.” The new biochemical evidence supports what archaeologists (and ancient Romans themselves!) have documented through historical records, artifacts, and features. In particular:
- Infrastructure: Ancient Rome was an amazingly effective administrator, with infrastructure stretching from the British Isles to the Middle East. Throughout the empire, Rome supplied not just roads, but the engineers, government officials, military officers, and businessmen to use them.
- Mille viae ducunt homines per saecula Romam. (A thousand roads lead men forever to Rome: All roads lead to Rome.) Nicely plotted Roman roads are still being found today!
- Trade: Commerce in ancient Rome included trade in raw materials (such as ivory from Africa), partly finished goods (such as silk from China) and finished goods (such as wine from Tuscany). Here is a nice, nice map of ancient Roman trade networks.
- These trade networks allowed for voluntary migration to urban centers such as Rome, Alexandria, or Antioch.
- The well-established slave culture and ever-expanding empire also allowed for involuntary migration from within the borders of the empire (conquered tribes from Germania) and outside it (imported slaves from sub-Saharan Africa).

- Migration in ancient Rome is very well documented “within the bounds of history, material culture, and epigraphy.” The new biochemical evidence supports what archaeologists (and ancient Romans themselves!) have documented through historical records, artifacts, and features. In particular:
- So, new evidence shows that people from the Alps and the Maghreb immigrated to Rome. Did native Romans, indigenous to what is now Central Italy, ever emigrate—leave Rome for the outer reaches of the empire?
- Yes, all the time. Soldiers serving in the formidable Roman military often left for years at a time, and many stayed and raised families in the places they were stationed: Britannia, Gaul, Hispania, Judea. Families also moved out of Rome for economic reasons—to seek greater social or financial opportunities, establish businesses, or find trading partners.
- Why is the new research documenting migrants in Roman necropolises so innovative?
- The new findings document the migration patterns of Rome’s poorer residents. Previous research (and the historic record itself) has focused on the movement of Rome’s wealthiest residents—those who could afford to engage in tourism. Researchers say “The historical record is notoriously biased towards elite men with money, power, and literacy and may not represent accurately the lives of the average voluntary immigrant or slave.” This research expands the historical record.
- How do researchers know the skeletons belonged to people from poor economic or social backgrounds?
- Burial in a necropolis was customary for the lower classes (elites were interred in mausoleums like this one), and the burials lacked valuable grave goods, such as decorations, markers, or objects.
