Q1961Marshallese stick charts encoded how ocean swells bend around islands, using curved ribs for wave patterns and cowrie shells or selected intersections for islands.
Marshallese navigators built charts from coconut ribs, fibre and shells, but their subject was not fixed territory. The curves modelled long ocean swells, currents and the disturbances made by islands. Often studied ashore and committed to memory rather than carried at sea, each chart trained a body to feel a moving landscape beneath the canoe.
