Vestibule of Unbroken Seals

The Vestibule of Unbroken Seals (designation Δ-19-VS.07.3.114) is an antechamber on the eastern approach to the Unbroken Circle, maintained for the reception and authentication of Chronostatic Seals presented in connection with the Principle of Unbroken Continuity. It is the only vestibule in the Tower whose working seals are required by standing order to remain unbroken, and the arrangement of the room exists almost entirely to make that requirement satisfiable.

Admission follows the general rules of the Vestibule School, with one departure: the Room of First Questioning, ordinarily the first chamber entered, is here the second. The first is a plain ante-room with a bench and no furniture otherwise, in which a petitioner must sit until a Keeper of the Third Grade has confirmed from the doorway that no seal has been carried into the vestibule in a broken state. Petitioners have been known to wait two days. The bench is considered part of the procedure.

Physical description

The vestibule is a low octagonal room of dressed grey stone, seven and a half paces across, roofed at a vault of eleven courses. Its eight walls carry eight niches; seven hold the stands and reading ledges of the seal clerks, and the eighth holds nothing. The empty niche is not a defect. Concordance records refer to it as the Niche of Reserve, and its vacancy is inspected at the start of every shift, because an occupied Niche of Reserve is the standard first indication that something has gone wrong.

Lighting is by four wick-lamps set in the corners of the floor margin, burning stair-oil of the ordinary grade. The lamps are trimmed at the fourth hour and the eighth. Nothing in the vestibule is permitted to be replaced rather than repaired.

History

The vestibule was opened in the Year 219 of the Unbroken Catalogue, eight years before the ratification of the Principle of Suspension, as a consequence of the embarrassment known in the records as the Affair of the Fourth Clerk. A clerk of the Circle's outer office, presenting a sealed delegation from Floor 412, carried a chronostatic seal in a satchel with a broken strap; the seal arrived intact but unaccompanied by any record of the strap, and the delegation was refused on the ground that the seal's continuity could not be shown to have been unbroken at every moment since leaving Floor 412. The clerk's name is not recorded, but the principle his case produced is quoted constantly: a seal is unbroken only if nothing about it has ever been broken.

The vestibule was built to make that principle workable. Petitioners now approach through a single door and surrender nothing; the seals are presented on a fixed ledge in the ante-room, where a Keeper observes them across the whole of the approach. In practice this means that a petitioner carrying several seals will be asked to make the approach several times.

Procedure and the Empty Niche

Once admitted, the petitioner presents each seal to a clerk, who reads its impression aloud and enters it in the vestibule's register. The register is bound in eight parts, one per wall, though the eighth part has never been written in. Seals are then returned to the petitioner unaltered. The vestibule does not open, examine, or reset a seal; the standing formula, printed above the inner door, reads: "The vestibule receives. The Lens judges."

The one substantive work the vestibule performs is the verification of designation. A repeated feature of the complaints in the Vestibule of Unspoken Appeals is a petitioner who has brought a beautiful and wholly correct seal, authenticated at great length, which turns out to be the seal of a different office. The clerks of Δ-19-VS.07.3.114 have petitioned three times for the right to keep a comparative shelf of known impressions, and have been refused each time, on the doctrine of the Niche of Reserve.

Scholarly disagreement

The Seventeenth Concordance holds, at Annex 4, that any seal broken inside the vestibule is "broken as though broken before," and so inherits the full filing consequences of a prior break, including review by the Hume-Locke Vestibule. The Nineteenth Concordance holds at clause 11 that a seal broken inside the vestibule has not yet entered it, and that the break therefore has no standing. Both are cited; neither has been withdrawn.

"A seal is unbroken if it is unbroken where it stands, and where it stands is the vestibule."

— Nineteenth Concordance, clause 11

The Gradient Purists of the eastern scriptoria have taken a third position: whatever a gradient seals, it seals permanently, and the interior of the vestibule is on the wrong side of its own gradient. The Vestibule of First Instance has declined to rule on the point, noting that it concerns a room and not a document.

Incidents

In the winter of Year 391 a lamp was found to have gone out with the register open and two clerks absent. The Office of the Eighth Niche was convened, sat for nine days, and concluded that nothing had happened, a finding which was itself entered in the register and which has since been cited more often than any seal ever received there. In Year 404 a Keeper of the Third Grade was reprimanded for allowing a petitioner to sit on the bench with a parcel on his knees, on the ground that the parcel blocked the Keeper's line of sight to the seals. The reprimand stands.

Toilets are on the floor below; petitioners waiting on the bench are advised to decide before sitting down.
