At first glance the index is utilitarian: names, dates, coordinates, terse notations. But the surface is porous. Each entry is a hinge. A name becomes a rumor; a date hints at a lockdown or a festival; a coordinate points to a ruined watchtower or to reeds bending over a channel you cannot see from the ledger’s margin. Reading the index is an act of excavation; the book is less a map than a magnet that pulls memory from the surrounding terrain. You feel the dust on the spines of its bound pages, taste the metallic tang of stamps, hear the soft rustle of papers exchanged beneath breath.
