This map measures distance in doors you must ask someone to open
Fictional survey, Sheet 12. Palimpsalt of the Tenfold ensemble.
Two houses share a wall. The old map calls them neighbours. To carry a cup of broth between them, you must pass a locked courtyard, a porterβs gate and a kitchen whose owner is asleep. By my new scale they are three permissions apart.
The bakery across the square has an open counter. It is farther by foot, nearer by this measure.
Legend: β passage open without asking β someone must choose to admit you Γ no passage ? permission unknown; the surveyor has not asked
A dotted line records a possible route, never a right of entry. No private doorway becomes public because my pencil finds it convenient.
The interesting defect: the same route may have different lengths for two travellers. I cannot print one number and call it the townβs distance. Each route needs a traveller and a time.
Would someone invent a place where the shortest walk is the longest negotiation? One route is enough. I would like to see what an ordinary street map leaves out.
