Archaeological Inquiry: Ladder of Inference, Ardboe Cross Case, and Johnson Readings

Structure of archaeological inquiry

The lecture revisits the core question: how do archaeologists ask questions and make sense of the world?
Emphasizes that archaeology relies on comparing patterns in material remains to understand shared, learned culture.
Wednesday’s main framework: the ladder of inference as a way to organize facts from empirical observations up to abstract inferences.
Key idea: culture is shared and learned, so it produces patterns that can be read in material remains; there is no objective standard for judging cultures, only patterns that emerge through comparative analysis.
The class will apply this framework to a case study to see how culture manifests in landscape and artifacts over time.

The ladder of inference (recalled from Wednesday)

Bottom: empirical facts, e.g., a pen exists and can be proven empirically.
As you climb, abstractions increase and standards for judging cultures become less objective.
The point: culture is shared and learned; because of that, it makes patterns that show up in material culture.
The necessity of comparison: without a fundamental comparative approach, you cannot detect awareness of culture.
The ladder helps explain how to move from raw data to culturally meaningful interpretations, while recognizing the subjective elements at higher rungs.

Case study: The Ardboe Cross, Northern Ireland

The Ardboe Cross is a tall high cross (~ ext{height} \approx 20\ \, ext{ft}), with carvings on all four sides; evidence links its style to crosses across Ireland and Britain.
It was built at an abbey (a community where monks and religious scholars lived) during the abbey’s period of wealth and influence; later, the abbey burns down or collapses (exact event unclear).
Current landscape includes a church ruin and a cemetery where people are still buried; modern headstones coexist with older ones, indicating long-term use of the site.
The setting provides a rich cultural landscape for reading shared patterns: how people commemorate the dead, engage with religion, and relate to time and memory.

Reading the landscape: cultural phenomena inferred from space

Caring for the dead and commemoration: headstones, flowers, maintenance of the grounds.
Religion/Christianity as a pervasive framework influencing landscape, burial practices, and ritual spaces.
Engagement with memory: cultivation of the grass, maintenance of graves, ongoing remembrance across centuries.
Evidence of social hierarchy: the large, expensive cross signals status; linking material expense to social power.
Public storytelling through imagery: the cross as a visual narrative in an era when most people were illiterate; the cross conveyed religious stories to a broad audience.
Temporal layering: the site shows a long history of use, with newer elements (headstones, Celtic revival references) appearing within an older medieval context.
The cross’s size and craftsmanship imply specialized skill (stone mining, carving, iconography) and public investment in monumental antiquities.

The role of temporality and repetition in archaeology

Repetition over long periods yields a robust archaeological signal; one-off events are less likely to be attested in the material record.
The Ardboe Cross, as a long-running symbol, helps archaeologists reconstruct patterns of power, religion, and identity across centuries.
The case demonstrates how repeated actions (e.g., building, burying, commemorating) create durable traces that persist in the landscape.

Cultural patterning and political identity in Northern Ireland

Northern Ireland’s modern political history frames how landscapes and monuments are read today.
Political symbols appear in burials and inscriptions (e.g., tricolor on a tomb), signaling IRA/Republican sentiment or Protestant/UK alignment, depending on the context.
The cross becomes a symbol not only of medieval Christianity but of later political identities and conflicts.
Personal names on headstones (e.g., John Coyle) memorialize contemporary political affiliations and groups, showing how identity discourse maps onto space.
The 19th-century Celtic revival reuses high-cross imagery in monuments and grave markers, linking medieval symbolism to modern nation-building and cultural heritage.
The coexistence of new and old monuments demonstrates how memory and identity are continually reworked in the landscape.

Connections between religious symbols, politics, and identity

The cross imagery and church ruins can be read as a convergence of religion and politics, challenging the idea that these spheres are always separate (a critique of secularism as a modern construct).
The landscape encodes multiple layers of meaning: medieval religious practice, 19th-century cultural nationalism, and contemporary identity politics in Northern Ireland.
The use of color (farben on modern headstones) mirrors the Irish tricolor, signaling continuity of national symbolism into private commemorations.

Theoretical readings: patterns, knowability, and jargon (Johnson readings)

Johnson’s readings emphasize the role of biases and the problem of knowability in reconstructing the past.
Biases are unavoidable; the task is to acknowledge and frame them rather than pretend they don’t exist.
Ley lines and other grand theories exemplify how interpretations can be both persuasive and contested; a single interpretation can be overturned by new evidence.
The use of jargon in archaeology: terminology can clarify but also alienate; vocabulary matters, but it should not obscure reasoning.
The readings argue for explicitness: articulate theory, method, argument, and the unsaid to understand a text’s full implications.
Some archaeologists reject theory as “atheoretical,” but the course argues that everyone uses philosophy to interpret evidence, whether they admit it or not.
A key point: every past claim is, at some level, hypothetical; without a time machine, we can never know everything with certainty. Accepting degrees of knowability helps evaluate competing interpretations.
Johnson’s primer for critical reading: identify (1) theory/philosophy, (2) method, (3) the central argument, and (4) what remains unsaid or implicit; this helps evaluate not just archaeology but any scholarly writing.

Key takeaways: theory, method, and knowability in archaeology

Theory vs. method debate: some scholars separate theory from method; others argue they are intertwined and contingent on each other.
Jargon can be a tool for precise communication but can hinder accessibility and inclusivity if overused.
Theory acts as a bridge from raw facts to interpretive claims; it helps explain how inferences are justified.
There are ongoing disagreements about the best way to do archaeology; the class presents a spectrum of approaches rather than a single “correct” method.
Knowability is probabilistic and graded; interpretive claims should acknowledge their limits and be open to revision with new evidence.

Practical implications for archaeology pedagogy and research

Use the ladder of inference to trace how empirical data become cultural interpretations.
Pay attention to landscape design, material culture, and inscriptions as sources of social meaning across time.
Recognize how politics, religion, and identity shape both the past and present readings of material culture.
Be explicit about biases and theoretical assumptions when interpreting sites or artifacts.
Apply Johnson’s four-part reading framework to any scholarly text: theory, method, argument, unsaid ideas.
Distinguish between what is known, what is inferred, and what remains unknowable; communicate degrees of confidence clearly.

Connections to previous lectures and overarching themes

Wednesday’s focus on the ladder of inference connects directly to today’s emphasis on how to structure archaeological inquiry through empirical data and abstract reasoning.
The Ardboe Cross case demonstrates the foundational principle that culture is patterned and legible in material remains when approached comparatively and with attention to time, space, and social context.
The discussion of politics and religion within a landscape ties into broader debates about secularism, identity, and power in archaeology and anthropology.
The theme of knowability and critical reading ties back to the class’s aim: to cultivate careful, evidence-based, and self-aware interpretation of past societies.

Quick reference to terms and concepts

Ladder of inference: a framework for moving from empirical data to abstract inferences and theories.
Shared/learned culture: culture that is collectively understood and reproduced, yielding recognizable patterns in material remains.
High cross: a tall, highly carved Christian monument used for preaching and as a public symbol; often around abbeys.
Abbey: a monastic community site; source of wealth and influence in medieval contexts.
Temporality: study of how time and timing shape interpretation of material remains.
Celtic revival: 19th-century movement reusing medieval Irish imagery (e.g., high crosses) for modern nationalist purposes.
Jargon: specialized terminology; can aid precision but may alienate non-specialists.
Theory vs. method: philosophical framing vs. practical procedures in archaeology.
Unsold/unsaid: what a text does not say but implies; important for critical reading.
Knowability: the degree to which past events or cultures can be known; often partial and contingent on evidence.

Numerical notes (LaTeX formatting)

Cross height: ext{approximately } 20 ext{ ft}
Time periods referenced: ext{10th century}, ext{19th century}, 1500 ext{s} (the 1500s; 16th century context is often implied), ext{15th century} ext{ to } ext{16th century} (contextual approximation mentioned in passages), etc.
Emphasis on repetition yielding robust records: qualitative, but grounded in the idea of long-term patterns rather than single events.
The lecture frames time scales as i) medieval Christianity, ii) nationalist revival in the 19th century, iii) contemporary memory and politics—spanning centuries, not just decades.

Final reflection

The Ardboe Cross case illustrates how culture is patterned and materially manifested, how symbolism shifts over time, and how landscape reading can reveal power, memory, and identity.
Johnson’s readings encourage critical engagement with theory, openness about biases, and careful analysis of what is said and unsaid in scholarly arguments.
The goal is to develop a nuanced, evidence-based, and ethically aware approach to interpreting past societies through material remains and landscapes.
