The Curator of Impossible Maps

The Helle Bequest occupied the long north room of the Merrith Collection, forty-one maps in shallow oak drawers, and for two years Cassia Orne had been the only living person who loved them.

They were maps of nowhere. That was the difficulty, the scandal, and—though she would not have confessed it to the trustees who paid her modest salary—the quiet enchantment of them. Every other holding in the Merrith could be checked against the world: the portolan charts with their spidering rhumb lines, the proud imperial surveys, the trench maps and the tube diagrams and the careful parish tithe-plans, all of them answerable, in the end, to some stretch of actual ground that a person could stand upon and verify. The forty-one were answerable to nothing. They depicted coastlines that matched no coast, archipelagos strewn across seas no sailor had named, a walled city called Anverre standing at the confluence of three rivers that existed on no other document in the history of the world. They were rendered with the patient, ravishing exactness of a man mapping his own back garden—every contour line sure of itself, every soundings-figure inked in the bay, every road labelled, every marsh hatched, every elevation profile drawn along the lower margin with the offhand confidence of direct observation. Marius Helle had drawn places that were not there as though he had walked every inch of them with a theodolite and a level and a great deal of time.

Cassia had catalogued them the way she catalogued everything, which was to say beautifully and without quite letting herself believe in them. Outsider cartography, she had written in the accession notes; a private mythology of considerable internal consistency; cf. the invented countries of certain solitary children, executed here with the technical apparatus of a professional surveyor. It was the sane explanation and she had clung to it, because the alternative explanations all had the texture of things she had stopped being allowed to believe somewhere around the age of nine. Helle had been the Merrith's curator for thirty-one years and its sole occupant for most of them, an unmarried, uncelebrated man who had died—or so the death certificate maintained—at his own desk in the long north room, with a half-finished map of a place called the Saltmarsh of Eddoe under his unmoving hand, the last contour line trailing off where the pen had left the paper. He had bequeathed the forty-one to the institution that had housed him, with a single sealed instruction in the deed of gift: that they be kept together, that they never be sold, and that the room be left a way for those who come back.
