Archaeological Methodology and Interpretations

From a surviving object to an interpretation

Material remains do not explain themselves. Archaeologists must move from observation—what survives, where it was found and what accompanied it—to interpretation: what it suggests about Roman life. A room’s dimensions can be measured, but deciding what people did there requires further evidence.

The most useful question is therefore not simply ‘Is this source reliable?’ but ‘What can this source support?’ A building can reveal access and the arrangement of spaces. Portable objects can suggest activities within those spaces. A wall painting provides evidence of decoration, but its present appearance may have been altered by fading or restoration. These different types of evidence work best together.

Pompeii: exceptional preservation, not an untouched time capsule

The eruption of Vesuvius in AD 79 buried Pompeii and Herculaneum, preserving unusually extensive evidence of first-century Roman city life. This makes the Vesuvian sites especially valuable: buildings and objects can often be studied in relation to one another rather than as isolated museum pieces.

However, burial did not leave everything untouched until modern excavation. Roman salvage operations and treasure hunters disturbed the ruins; tunnels crossed buildings, with some dating as late as the fourth century AD. A canal was also constructed through Pompeii between 1592 and 1600.

Even before burial, objects could be moved or discarded and buildings could be renovated or reused. A surviving arrangement is therefore not automatically evidence of a permanent way of life. When interpreting a find, ask whether its position reflects ordinary use, storage, abandonment or later disturbance. This does not make Pompeii useless: it makes careful attention to context essential.

Why the find location matters

Archaeological context includes both where an object was found and what was found with it. Shape alone may suggest a use, but associated finds can test that suggestion.

Penelope Allison challenged the conventional names casseruola (‘casserole dish’) and forma di pasticceria (‘pastry mould’). These names reflected similarities to nineteenth-century household objects. They encouraged scholars to assume a food-preparation function, although the archaeological associations did not support that assumption. David Mimno’s analysis likewise found little or no connection between these categories and food-preparation objects.

The lesson is not that we now know their precise alternative use. It is that a modern label is not proof of an ancient function. A stronger interpretation compares an object’s form, find location and associations instead of allowing its name to decide the answer.

Objects are often removed after excavation for secure storage and conservation. This protects them, but makes accurate records crucial. Comparing similar objects in storage can reveal patterns of shape while overlooking the different contexts in which they were used.

A room can have more than one use

Architecture does not necessarily determine activity. Small enclosed rooms called cubicula are conventionally described as bedrooms, but Allison’s research and Mimno’s analysis challenge the assumption that this was their consistent function. The finds associated with these rooms include storage fittings and pottery, rather than providing a straightforward pattern of sleeping equipment.

This does not prove that nobody ever slept in a cubiculum. It shows why ‘small enclosed room’ and ‘room used for sleeping’ must not be treated as identical claims. Household spaces could serve several purposes or change use over time.

Fixed features may provide stronger clues. Hearths help identify kitchens, while stairs identify stairways. Yet there is a danger of circular reasoning: if a room was classified as a kitchen because it contained a hearth, the hearth is not an independent discovery confirming that classification. Other associated evidence should also be considered.

Patterns, quantities and the limits of a sample

Counting finds can strengthen an interpretation. In comparative household research discussed by Mimno, loom weights illustrate why quantity matters. The organic parts of a loom may decay while its weights survive. One isolated weight is weak evidence for weaving in that room; a group of a dozen or more in the same location is much stronger evidence for a loom.

Patterns across many rooms can also test assumptions. Mimno analysed a database containing more than 6,000 artefact records from 30 architecturally similar atrium-style Pompeian houses. His statistical approach allowed rooms to have mixtures of functions rather than assigning each room one fixed activity.

However, those houses are a sample, not the whole Roman world. Their results cannot automatically describe every household in Pompeii, still less every home in Rome, Ostia or Herculaneum. Statistical methods also depend on expert decisions about how objects are classified. They can challenge assumptions, but do not remove interpretation altogether. Nor does the absence of two objects together necessarily prove that they were unrelated: a small sample may simply fail to preserve the connection.

Excavation and reconstruction change what audiences see

Official excavations began at Herculaneum in 1738 under Charles of Bourbon, and at Pompeii ten years later. Early work prioritised acquiring impressive artefacts to enhance the kingdom’s prestige. Limited records make it difficult to reconstruct exactly what was found and how it was altered.

Leaving excavated buildings open to visitors helped create Pompeii’s appeal as an open-air ancient city, but also exposed remains to deterioration. Frescoes faded; attempts to improve their appearance included applying water and varnishes. A painting’s current colour or clarity cannot therefore always be treated as its ancient appearance.

After becoming director in 1924, Amedeo Maiuri aimed to create a ‘living museum’. Extensive reconstruction helped visitors imagine an inhabited city, but some reconstructions departed from archaeological evidence, and objects were sometimes displayed away from their find locations. A convincing display can make an interpretation feel certain without making it better supported.

Ancient audiences: interpreting the House of Menander

An audience’s interpretation depends on its knowledge, interests and relationship to the material. The House of Menander at Pompeii offers a concrete example. Its modern name comes from a fresco on the south side of the peristyle, the colonnaded courtyard or garden, associated with Menander, a Greek writer of comedy. It was not Menander’s own house.

An ancient visitor who recognised the playwright could have understood the decoration as expressing an interest in theatre and Greek culture. It might also have presented the household as educated and cultured. Someone unfamiliar with Menander might instead have appreciated the painting mainly as decoration. These are plausible differences in response, not recorded reactions from particular visitors.

The owner’s intentions and a visitor’s response need not have been identical. Displaying a playwright could communicate a cultivated identity without proving how much Greek the owner knew or how often they attended performances. The house’s large size and private baths provide separate evidence of wealth; the painting supports a different judgement about cultural interests or their presentation.

There is also uncertainty about the figure’s identity: an alternative interpretation identifies him as the owner reading Menander’s works rather than Menander himself. Both interpretations can suggest a connection with Greek literature, but they make different claims about whom the painting represents. This shows why a useful interpretation can remain possible even when one detail is disputed.

Modern audiences: names, expertise and presentation

Modern audiences also differ. An early royal collector might value an impressive object as a prestigious possession. An archaeologist investigating household work would place greater emphasis on its find location and associated objects. A tourist viewing a reconstructed room might understand it as a complete scene of ancient life, even where some details are modern additions.

House names can guide—and mislead—these audiences. At Pompeii, the name ‘House of Loreius Tiburtinus’ arose from electoral notices on the exterior urging votes for Loreius or Tiburtinus. Those notices did not establish who owned the house. A bronze seal found inside instead supports its identification with the last known owner, Octavius Quartio. The two names illustrate competing interpretations based on different kinds of evidence: public political writing and an object associated with an individual.

Similarly, a modern visitor could mistake ‘House of Menander’ for a statement of ownership. An informed interpretation distinguishes the modern naming convention from evidence about the ancient household.

Interpretation aids shape those responses. Research conducted at Pompeii in 2011 found that visitors encountered different levels of information through signs, guidebooks, audio guides and guided tours. Some guidebooks included inaccessible properties or used names and numbers that did not match those on site. Such differences affect what visitors see and how they understand it.

A sound judgement brings these strands together: identify the observation, explain the interpretation it supports, consider alternative explanations and qualify the conclusion. Material remains are valuable evidence precisely when we examine both their ancient context and the later history that has shaped their survival and presentation.

Evidence and inference

• Observation: what survives and where it was found.
• Interpretation: what it suggests about use or meaning.
• Combine architecture, objects and decoration; do not let a modern name determine ancient function.

Key methodological issues

• Survival and disturbance: AD 79 preserved exceptional evidence, but salvage, tunnelling and later work altered it.
• Context: removal protects objects, but makes find records essential.
• Flexible use: room shape does not establish one permanent function.
• Quantity: groups of finds can support conclusions more strongly than isolated objects.
• Sample bias: 30 similar Pompeian houses cannot represent all Roman households.
• Restoration: fading, reconstruction and relocated displays affect what modern viewers encounter.

Examples to recall

• Casseruola and forma di pasticceria: modern culinary names are not proof of food-preparation use.
• Cubicula: do not automatically equate small enclosed rooms with bedrooms.
• Maiuri’s ‘living museum’: vivid presentation could depart from archaeological evidence.

Audience interpretations

• House of Menander: a knowledgeable ancient visitor might recognise theatre and Greek culture; another might mainly appreciate decoration. The figure’s identity is disputed, and the modern house name does not identify its owner.
• House of Octavius Quartio: electoral notices produced the misleading name ‘Loreius Tiburtinus’; a bronze seal provides different evidence of ownership.
• Modern audiences: collectors, archaeologists and tourists have different interests. Reconstruction, access and interpretation aids shape their responses.

Judgement structure: observation → supported interpretation → alternative or limitation → qualified conclusion.
