01 · The hinge

Follow the material pressure

Read 841 AD as a hinge, not a label. Vikings established a fortified base at Dublin. That places “Dublin Becomes a Longphort” between “The Book of Kells Shines” and “Waterford Returns to the Norse”, while one record was changing the range of choices available in the next.
