The Atlas of Lost Directions

Definition and scope

The Atlas of Lost Directions is a cartographic compilation held on Floor -12, within the Chamber of Unspoken Directions, and catalogued under the general rubric of directional relics alongside the Galleria of Fallen Cardinal Directions. It comprises fourteen gatherings of vellum, each leaf bearing bearings — routes, headings, and accessions that were once operative within the Tower's circulation and that have since ceased to be. Unlike ordinary atlases, which record directions that may still be followed, the Atlas records only those that may not.

The Atlas is frequently confused with the Whispering Atlas of Lost Capitals, a derivative of the Master Atlas assembled by Vesel Andrunne from proclamations of the Office of Discontinued Addresses. The confusion is understandable and is itself the subject of a standing annotation in the catalogue. The distinction was settled, provisionally, by the Controversy of the Whispering Atlas, whose findings the Office of Standing Directions has declined to extend beyond the specific case.

History of compilation

The Atlas was begun in Cycle 774 by the scribe Ordwin Pelassier, then attached to the scriptorium of the Fifth Spiral. Pelassier's original remit was narrow: to transcribe the headings recorded on the reverse of extant survey plates that had been struck from circulation by Concordance order. Within three years the remit had expanded to include verbal directions, directions given in error, and directions that had been given correctly but to the wrong party.

Pelassier's working method is described in his own marginalia: he would walk each recovered direction to its terminus, where a terminus remained, and record what he found there. Where no terminus remained, he recorded the absence. The result is an Atlas in which roughly a third of the leaves describe places that are not present to be described. The Official Latent Atlas classifies this technique as "Non-Linear Parametric," though the classification was applied retroactively and is disputed.

Pelassier died in Cycle 791 without naming a successor. The scriptorium appointed one anyway.

Structure and holdings

The fourteen gatherings are sewn in a fixed order that no clerk has been able to justify. The first gathering contains directions that lost their validity following the dissolution of the Provisional Maps, an event theorised to have fed the phenomenon catalogued elsewhere as the Whispering Atlas. The second and third gatherings contain directions to rooms on floors whose numbers are no longer assigned. The fourth gathering is blank but for a single line in Pelassier's hand, which reads: "Here was the way to the Lamp Room; there is no longer a Lamp Room."

The eleventh gathering is the most consulted. It contains directions that are still, in some sense, in force, but that lead only to other lost directions — a chain with no terminal member. Consultation of the eleventh gathering is permitted only under the seal of a Keeper, and visitors are reminded that pencils may not be brought past the second antechamber of the Chamber of Unspoken Directions.

Custody disputes

The Atlas has been held by four separate offices since Pelassier's death. The most consequential transfer occurred in Cycle 841, when the Office of Standing Directions removed the Atlas from the Fifth Spiral on the grounds that directional matter fell within its competence. The Keeper of the Fifth Spiral contested the removal, arguing that custody of gatherings sewn at the Spiral could not be transferred without the Keeper's countersignature. The dispute was referred to the Inquest of the Whispering Atlas, which ruled on an unrelated matter and did not return to it.

A second dispute, opened in Cycle 902 and still open, concerns the eleventh gathering specifically. The Office of Standing Directions attempted to reconstruct Tylus's spoken directions of Cycle 411 and requested the Atlas as a comparator. The request was refused on the ground that Tylus's directions were never lost — merely misfiled — and therefore fall outside the Atlas's remit by definition. Both offices have filed letters. Neither has read the other's.

Scholarly disagreement

Two readings of the Atlas prevail. The first, associated with the annotations appended to In re: The Whispering Atlas, holds that the Atlas is a memorial document: it records directions that once existed and no longer do, and its value is historical. The second, associated with the marginalia of the anonymous reader who transcribed plate 9 of the Whispering Atlas of Lost Capitals and was subsequently investigated by the Office of Discontinued Addresses, holds that the Atlas is predictive — that directions appear in it before they are lost, and that Pelassier, far from recording absences, was forecasting them.

The Whispering Atlas Petition of Cycle 866 attempted to resolve the question by commissioning a third reading. The commission reported in Cycle 869 that the two readings are not mutually exclusive and that the Atlas is therefore both a memorial and a forecast, depending on which gathering is open. This report has been cited eleven times and read, by the Librarians' own count, twice.

Access and reproduction

The Atlas is available for consultation by appointment, on Floor -12, between the hours of the second and fifth apertures. Reproduction of any gathering requires the countersignature of a Keeper and a dispensation of the kind ordinarily granted for the Laying of vectors at the Galleria. Two copies are known to exist: one held in the reliquary of the Chamber of Unspoken Directions, and one unaccounted for since Cycle 841.

The catalogue entry for the Atlas remains, in the Librarians' assessment, adequate.
