The text below is meant to be read aloud at the start of the discussion section. It compresses the week's lecture into a few minutes and hands the room to the five tasks. The fuller notes that follow are for setting each task up in turn.
This week's lecture made one argument in many forms: that the physical world of Greece — the mountains that fragment it, the sea that knits it back together, the thin soils, the seasonal winds, the metals the land does not contain — structured what was possible without ever dictating what actually happened. Geography sets the terms; people make the choices. The mountain does not build the pass; it only makes one necessary.
The discussion takes that argument and tests it to its limits, in five tasks. The first three follow the geographical thread across time: a single place pulled apart into what it constrains and what it affords; the collapse around 1200 BCE, and why some nodes in the system survived it while others did not; and the logic of where the Greeks chose to plant their colonies — together with the equally telling places they left alone. The fourth turns to the laboratory, asking what science, reading the isotopes locked in ancient bone, can honestly tell us about how one person ate and where they came from, and where its certainties run out. The fifth returns to the water, to the one space the polis could regulate least and mistrusted most.
Running through all five is a single discipline: knowing the difference between what the evidence establishes and what it merely permits. A harbour invites a settlement but does not found one. A skeleton's chemistry fixes a diet and a childhood region but cannot recover a life. The sea makes the fisherman's marginality likely without making it necessary.
So as you work, keep asking the lecture's central question in each new form: where does the landscape stop explaining, and human choice begin? That boundary — between the possible and the actual — is the real subject of the week, and each task marks it in a different place.

Setting up the five tasks
The first three tasks develop the geographical argument across the eras; the fourth introduces isotopic science; the fifth engages the sea and its fishermen directly. Each was signalled in the lecture; the notes here draw the line between that framing and the work the groups will do.
Task 1Constraint and affordance
This is the lecture's framework made concrete. Groups take a single location and separate two physical features that constrain its political or economic development from two that enable it, then add a dietary dimension — what the terrain makes easy to eat and what it makes hard to get. The decisive question is whether geography and diet alone could have predicted the role that place came to play in Greek history, or whether they only narrowed the possibilities. This is exactly Horden and Purcell's "paradoxical coexistence" of fragmentation and connectivity, worked out on a single map reference. The verdict to aim for is a careful one: geography rarely predicts an outcome; it shapes the odds.
Task 2Connectivity under stress
The collapse of around 1200 BCE pulled down nearly every node in the eastern system the lecture described — yet not evenly. Groups are asked to propose a geographical explanation for why Cyprus and Egypt weathered the collapse better than Ugarit or the Mycenaean palaces, using the framework built across the earlier eras. The sharper, second move is to test that explanation against its own limits: Broodbank names "ubiquitous uncertainty" as a fundamental feature of the Mediterranean, and the task asks whether the collapse supports or complicates that idea — and, crucially, to name the single most important non-geographical factor the explanation cannot account for. This is the task where the lecture's caution about the reach of geographical explanation is most directly examined.
Task 3Colonisation geography and hinterland logic
Here the argument moves to the archaic colonising movement of Era V. Groups choose two foundations from different regions — one western, one Black Sea or Levantine — and identify the specific geographical logic of each: harbour quality, river access, the size of the agricultural hinterland, proximity to metals, control of a route. Cunliffe's claim that colonial and trade networks followed maritime routes rather than spreading overland is the model to test. The most revealing step is the negative one the lecture's whole method invites: naming a geographically obvious site the Greeks did not colonise, and explaining why geography alone cannot account for the pattern. Affordance, again, is not destiny.
Task 4What the bones can and cannot tell us
This task is as much a critical-thinking exercise as a historical one, and it follows directly from the lecture's section on the body as evidence. Pairs are given a realistic isotopic profile of one Bronze Age individual from the northern Peloponnese: a carbon signature pointing to a cereal-based diet with a little marine protein, a nitrogen value suggesting occasional meat or fish, and — most strikingly — a strontium ratio in the tooth enamel that does not match the local geology but fits the Aegean islands or eastern Attica. The work is to state plainly what this establishes (a childhood spent elsewhere, a broadly known diet), what it cannot (almost everything else about the life), and what further evidence would help. The pay-off connects to the whole document: a person who grew up on the islands and died inland in the Peloponnese is geography and biography pulling against each other in a single skeleton.
Task 5The sea the polis could not own
The lecture closed on the untamable sea, and this task takes up its social and ideological edge. Lytle argues that the polis could not effectively regulate the sea or the fishermen who worked it: the sea was koinē, common to all, and fishermen lived largely outside civic structures. Davidson shows that fish consumption was nonetheless intensely policed — not by law at the water's edge but by ideology at the table. Groups weigh what that contrast reveals about how Greek society actually controlled behaviour, compare the standing of the fisherman with that of the farmer and the transhumant herdsman, and ask whether the sea's deep cultural ambiguity — nourishing and death-dealing at once — helps explain the fisherman's marginal place. The forward link is the one the lecture planted: the sea-gods belong to an older cosmological order than the Olympians, and the discussion may ask whether that mythological marginalisation runs parallel to the civic one, or is mere coincidence.
