Attend class regularly (& listen) … → Many clarifications, tips, announcements, reinforcement & reviews of materials/concepts. (2). Take notes on lectures, etc. … → The act of writing down notes, even with most course materials and instructions online, serves as an invaluable aid to one focusing on a class topic and retaining information better. (3). Complete the required textbook readings, and/or review the ppt., prior to the specific class day … → This will provide greater clarity and comprehension of the material, and will enable asking focused questions where something may be less clear (in the textbook or lecture). (4). Ask questions during the class if you are confused/wish more data → The class is an ideal place to ask for more clarity or further information not contained in the textbook, ppt., and/or lecture (If nobody asks questions, the lecture proceeds …). (5). Complete optional materials: → Additional reinforcement, studying & bonus? https://howtostudyincollege.com/how-to-get-good-grades/note-taking-strategies/ Renfrew and Bahn 2019 (8th. Ed.)

Introduction: • Humanity = often defined by tool-making abilities. Progression: Stone →AE → Fe → computers This chapter assesses: • How artifacts = made & used Different approaches: a. Archaeological b. Scientific analysis c. Ethnographic d. Experimental • Each artifact’s manufacturing process & application = best understood by closest modern manufacturer & user of a similar technology & item → Industrial archaeology.

Gates Introduction to Archaeology: Renfrew & Bahn 2019 (8th ed.): chp.8 8. How Did They Make Use of Tools? Technology. 1.2. Survival of the evidence: • Biased preservation may affect the surviving artifacts/technology • E.g., Palaeolithic: - Stone tools survive mostly - Few wood & bone items survive - Except wet, cold, & dry sites, sometimes imprints, hollows, soil discolorations, etc. • E.g., A “pseudomorph” (hollow) at a Middle Paleolithic site in NE Spain (Abru Romani) → yielded a hollow from a pointed wooden Ukraine: stick (1 m long) ca. 50,000 BP. Palaeolithic • Some ancient depictions = tools: Gontsy E.g., Boomerangs in Australia mammoth bone hut • Other evidence from: E.g., Sword-cuts; pick marks; etc. site Medieval fish basket Introduction to Archaeology: Renfrew & Bahn 2019 (8th ed.): chp.8 8.

How Did They Make Use of Tools? Technology. 1.3. Are they artifacts at all? • Archaeologists need to determine whether each item found = purposefully made/used? OR = by-product of manufacture? - Paleolithic flakes = less obvious! - “Eoliths” human-made vs. natural. Analysis of stone tool production → revealed “bulb of percussion” = left on “human-made tools” - Nature leaves irregular scars, fracturing (heat; frost; falls) → Eoliths = NATURAL. - Earliest tools = harder to discern from natural items (see context) - Now know some animals use tools (e.g., Chimpanzees) → no longer defines humanity (isolated finds =?)

Interpreting the evidence: Using ethnographic analogy: • Careful use of ethnography & ethnoarchaeology aids in assessing ancient technologies: - Generally people use readiest materials for daily, ordinary work (e.g., transitory tools). - Many people expend time & labour on long-term tools (e.g., hardier, quality tools) • Rel. % of artifacts = various meanings: - Abundant items may = cheap items - Uncommon items may = valuable • Assessing meaning: - 16th Cent.

The presence of a sword? puncture hole, and repair work, on an elaborate, “ornamental” metal shield (in early La Tene style: 320174 BC) revealed that such shields were used in battle sometimes, and contradicted earlier notions that ornate metal shields had been restricted to status items for ritual offerings and ceremonial usage.

Plating: • Plating joins metals together by various means • E.g., Peruvians evidently used a form of electrochemical plating to join valuable metals in early centuries AD (early Moche) • Apparently heat had been used to join gold to copper surfaces on some figurines, masks, & ornaments. • It is superficially similar to modern electroplating. • BUT, an aqueous solution of minerals and salts indigenous to Peru had apparently been boiled (5 min at 650-800C) to enable bonding between the surfaces. • Otherwise, electroplating appears in late Medieval/Renaissance Europe.

Iron and steel: Iron becomes popular in Near East ca. 1000 BC+ It is absent in Americas prior to Columbus (nb: *Meteoric iron in Arctic). Meteoric iron occurs naturally and is known early throughout Near East. Iron = harder to reduce than copper, but begins at 800C (1472F), with a melting temperature at 1540C (2804F) Many minerals need to be extracted from iron ores (by slagging): Late 13th cent.

How Did They Make Use of Tools? Technology. Cast iron: • A more complex furnace installation is required. • Some examples appear in 6th cent BC Greece • Cast iron = a brittle alloy of iron • It has a lower melting point • It has 1.5% - 5% carbon content Steel: E.g., cast iron •Buddha Steel is iron with 0.3% - 1.2% carbon statues • It is easily worked • It hardens with cooling • True steel appears in the Roman period. • Carburizing → made a similar product.

Damascus steel SUMMARY: Introduction to Archaeology: Renfrew & Bahn 2019 (8th ed.): chp.8 8. How Did They Make Use of Tools? Technology. 6. Summary: • Archaeologists can recover and extrapolate much information on ancient technology by excavation, analysis in laboratories, ethnographic data, and experimenting (e.g., reconstructing items, events, etc.). • The archaeological context and ethnography may suggest the function(s) of an artifact, while microwear analysis reveals likely past usage(s). • Microwear analysis relies on running experiments to see what usages leave specific traces on a given tool type and material. • Ethnographic studies are still invaluable for living crafts persons using similar technologies for comparing known living technologies with past similar ones. • Such ethnographic studies help mainly in assessing how ancient technologies MAY have functioned, using similar items, materials, and contexts. • The absence of more definite information from past textual-pictorial records leaves archaeologists with having to reconstruct a range of possibilities to probabilities using a broad range of evidence: excavation, analysis, ethnography, and experimentation.
