🏺 Archaeology: How We Know What We Know

What you’ll learn

1. It's Not Treasure HuntingGrasp the discipline's central claim: archaeology studies context, not treasure, and an object stripped of context is nearly meaningless.An artifact's meaning lives in its context — its layer, position, and associations. Looting destroys that information permanently even though the object survives, which is why archaeologists treat context as the most valuable and fragile thing at a site.
2. The Science of What People Threw AwaySee why discarded material (middens, garbage) is a richer, more honest record than monuments.Monuments send curated messages; refuse does not. Middens record real diet and daily life across generations. William Rathje's Garbage Project applied the method to modern landfills, showing that what people discard contradicts what they report — material evidence has no incentive to flatter.
3. Reading Time in the DirtUnderstand stratigraphy and the law of superposition as the framework for reading time on a site.Deposits build up in layers over time; in undisturbed ground, lower is older and upper is younger. A section reads as a calendar of events. Later intrusions (pits, graves) cut down into earlier layers and must be recognized to un-mix the sequence.
4. You Can Only Dig a Site OnceUnderstand that excavation is irreversible destruction, making recording paramount and looting catastrophic.A site can be dug only once; removing a layer destroys it, so the meticulous record is the only thing that survives. This makes archaeology unique among sciences, justifies its slowness, and explains why looting — which produces no record — is total, permanent loss.
5. Putting Things in Order, Before ClocksDistinguish relative from absolute dating and understand seriation.Seriation dates by style: fashions (e.g. pottery forms) rise, peak, and fade, so ordering them by frequency yields a sequence. Flinders Petrie pioneered it in 1890s Egypt. Relative methods give order; absolute methods give years — and before radiocarbon, archaeology had mostly the former.
6. A Clock Made of Carbon — and Fixing ItUnderstand radiocarbon dating, half-life, and why calibration by tree rings was necessary.Living things absorb carbon-14; at death it decays with a half-life of ~5,730 years (labs report using Libby's 5,568 for consistency), so measuring what remains gives a date. Because atmospheric carbon-14 varied, radiocarbon years differ from calendar years; dendrochronology built the IntCal calibration curve that corrects them.
7. Finding Sites Without a ShovelUnderstand non-invasive survey and remote sensing — field survey, aerial photography, geophysics, LiDAR.Because digging destroys, most modern archaeology finds and maps sites without excavation: field walking, cropmarks from the air, magnetometry and ground-penetrating radar, and LiDAR, which strips forest canopy to reveal ground features — transformingly so for the Maya lowlands.
8. From Potsherd to StoryUnderstand the inferential gap between evidence and interpretation, and how science tightens it.Evidence (postholes, bones, orientation) is mute; turning it into meaning (house, diet, belief) requires inference, which good archaeology flags honestly. Middle-range theory and ethnoarchaeology strengthen the bridge; isotope analysis of teeth shows how hard tight science can bite, revealing where an individual grew up.
9. Pompeii and Troy: Two Sites, Two LessonsUse Pompeii and Troy to see what catastrophe preserves and how careless digging destroys.Vesuvius sealed Pompeii in 79 CE, freezing daily life; Fiorelli's plaster casts recover human forms from voids left in the ash — meaning read from absence. At Troy (nine stacked cities), Schliemann trenched so fast he destroyed the very layers he sought — archaeology's cautionary tale.
10. Whose Past Is It?Engage fairly with repatriation and the discipline's colonial history without adjudicating.Many famous antiquities were taken under colonial power (Parthenon Marbles, Benin Bronzes; 'Priam's Treasure' is claimed by four nations). Arguments for retention (universal access, legality at the time) and return (consent, identity, looting) are both serious. NAGPRA (1990) requires returning Native American remains and sacred objects.
11. Ancient Aliens and the Real ThingRecognize pseudoarchaeology as a named, refuted phenomenon and articulate how real archaeology differs.'Ancient aliens' and lost-race theories disproportionately deny non-European peoples credit for their own monuments — often old racism in disguise. Methodologically, real archaeology starts from evidence and can be proven wrong; pseudoarchaeology starts from a conclusion and can't. Falsifiability is the dividing line.
