Artifact (archaeology) Study Guide

📖 Core Concepts Artifact – any object made or shaped by humans (tools, art, etc.). In archaeology it specifically means an item recovered by excavation. Object – museum term for the same physical item; “artifact” is the archaeological term. Ecofact – natural material (e.g., plant remains, fire‑cracked rocks) that was not modified by humans. Feature – non‑portable evidence of human activity (hearths, roads, pits). Manuport – a natural object moved by people but left unmodified (e.g., a seashell carried inland). Geofact – a natural stone that merely resembles a tool; not human‑made. Biofact – animal bone or other natural remain; becomes an artifact when carved or altered. Matrix – the physical material (soil, sediment, etc.) that contains an artifact. Provenience – the exact three‑dimensional location of an artifact within its matrix. Provenance – the complete ownership and location history of an artifact after discovery. Primary Context – matrix and provenience are unaltered since deposition. Secondary Context – matrix or provenience have been changed by natural or human processes. Material Culture – the set of physical artifacts produced by a society; distinct from the people’s ethnic identity (“pots are not people”). Relative Dating – ordering artifacts relative to one another without assigning calendar years. Historical Dating – assigning ages using written records or known historical periods. Typology – grouping artifacts by shared shape/material to infer chronological development. --- 📌 Must Remember Artifact = human‑made; Object = museum label; Artwork = disciplinary context. Ecofacts ≠ artifacts; Features ≠ portable objects. Geofacts can look like tools but lack manufacturing marks. Primary context = “original packaging”; secondary context = “re‑packaged”. Matrix = the “box”; provenience = the exact spot inside the box. Provenance tracks post‑excavation ownership, not the original deposition. Relative dating → sequence only; historical dating → calendar years if records exist. Typology assumes gradual stylistic change over time. --- 🔄 Key Processes Behavioral Process Acquire raw material → Manufacture → Use → Discard. Transformational Process (after burial) Natural forces (soil pressure, water, bioturbation) or later human activity (re‑use, looting). Context Shift Primary → (transformational) → Secondary. Authentication Look for manufacturing marks (flaking, hafting, symmetry) → Compare with local site attributes → Confirm human origin. --- 🔍 Key Comparisons Artifact vs. Object – Human‑made item vs. museum‑used term for the same item. Artifact vs. Ecofact – Modified by humans vs. natural, unmodified remains. Artifact vs. Feature – Portable object vs. non‑portable activity evidence. Artifact vs. Geofact – Human‑made vs. natural stone that merely resembles a tool. Primary vs. Secondary Context – Unaltered matrix/provenience vs. altered by post‑depositional processes. Material Culture vs. Ethnicity – Physical objects produced vs. the people’s cultural identity. --- ⚠️ Common Misunderstandings Ecofact = Artifact – Ecofacts are natural; only modification makes them artifacts. Depth = Age – Depth only suggests age if the context is primary and stratigraphy is intact. All stones = tools – Many are geofacts; look for systematic flake patterns. Typology gives exact dates – It only provides relative sequence, not calendar years. Provenance = Provenience – Provenance is later ownership; provenience is the find spot. --- 🧠 Mental Models / Intuition Artifact = “hand‑made product”; Ecofact = “hand‑picked natural”. Feature = “hand‑made setting” (the space where activity happened). Primary context = “still in its original wrapper”; Secondary = “re‑boxed after shaking”. Provenance = the artifact’s “biography” after discovery. --- 🚩 Exceptions & Edge Cases Manuports – natural objects moved by humans but not altered; still not artifacts. Biofacts → Artifacts – a raw bone becomes an artifact only after carving or shaping. Secondary Context – artifacts may be re‑deposited (e.g., in a later pit) and still retain diagnostic features. Geofacts – may be misidentified; require careful microscopic or use‑wear analysis. --- 📍 When to Use Which Lithic Analysis – for stone tools, flake scars, reduction sequences. Ceramic Analysis – for pottery; examines temper, slip, firing, and stylistic traits. Faunal Analysis – for animal bones; reveals diet, trade, status. Relative Dating – when no written record; use stratigraphy, association, typology. Historical Dating – when artifacts are found in contexts with dated documents or known historical layers. Typology – to construct a chronological sequence within a culture or region. --- 👀 Patterns to Recognize Uniform typology within a layer → likely same time period. Wear polish & conchoidal fracture on stone → intentional knapping. Consistent temper and paint on pottery → same production workshop. Cluster of manuports in a habitation zone → possible raw material transport route. Increasing depth of similar artifacts → possible chronological gradient (if primary). --- 🗂️ Exam Traps Distractor: “Ecofacts are artifacts because they are found in the same layer.” – Wrong; they lack human modification. Distractor: “All features are portable objects.” – Incorrect; features are non‑portable activity evidence. Distractor: “Typology provides absolute calendar dates.” – Only gives relative ordering. Distractor: “Looting is acceptable if artifacts are later displayed in museums.” – Ethically false; looting bypasses scientific context. Distractor: “Primary context means the artifact is old.” – Primary refers to unaltered context, not age.
