Definition
An interpretive model that reconstructs an individual artefact's sequence of states and contexts—from production and modification through use, exchange, repair, reuse and disposal—to explicate how material transformations embody social relations, practices and trajectories over time.

Principle

Principle
Tracing discrete changes in an object's material form, context and uses reveals vectors of social interaction (ownership, exchange, repair, symbolism) that are not visible from a single momentary context alone.

Demonstration

Demonstration
Illustrative Scenario → Archaeologist records manufacture marks, early wear, evidence of repair, and secondary deposition for a ceramic vessel. Recognition of these sequential traces leads the analyst to infer successive social roles (production in one community, functional reuse in another, ritual deposition) and to generate testable hypotheses about trade, maintenance practices and shifting meanings.

Misapplication

Misapplication
Interpreting an object's life as a single unified biography (teleology) that attributes all material changes to one continuous actor or intention; the error conflates coexisting uses, post-depositional alteration, or multiple proprietors into a single narrative rather than treating sequence and multiple agents as interpretive variables.

Consequence

Consequence
Proper application yields finer-grained hypotheses about social networks, technological practice and value regimes and guides targeted sampling, contextual analysis and provenance studies; it also increases sensitivity to taphonomy and curator actions that can obscure sequences.

Reversal

Reversal
When objects have been intentionally curated, restored, or fabricated to present a particular history (e.g., modern replicas, curated heirlooms) or when stratigraphic and contextual information is irretrievably mixed, sequential reconstruction either misleads or becomes impossible and the model must be set aside or heavily qualified.

Boundary

Boundary
Clearly within: a portable artefact with measurable manufacture traces, wear patterns, reparations and contextual associations permitting temporal sequencing. Boundary case: a museum object re-coated and re-labeled several times—material clues exist but are contaminated by recent interventions. Clearly outside: applying the concept to an abstract social institution that leaves no material signature to sequence.

Semantic Tension

Semantic Tension
Tension between object-centered biographies (focusing on the artefact's transformations) and assemblage- or practice-centered approaches that prioritize aggregated patterns or human actions over singular object histories; each constrains the kinds of inference justified from the evidence.

Synthesis

Synthesis
Object biography reframes artefacts as trajectories—vectors that link producers, users and contexts across time—so that material change becomes evidence about social relations rather than merely an attribute to be classified.
