The Cartographer Tries to Map a Way to Zion

We watch as the cartographer, used to assuming control over a place by mapping it ('I never get involved / with the muddy affairs of land'), is gradually compelled to recognise a wholly different understanding of place, as he tries to map his way to the rastaman's eternal city of Zion. As the book unfolds the cartographer learns that, on this island of roads that 'constrict like throats', every place-name comes freighted with history, and not every place that can be named can be found.
