Aperture 7 Containment Atrium

Aperture 7 Containment Atrium is a sealed interior volume of the Aperture 7 complex, occupying the whole of Floor 404 and the maintenance gallery directly beneath it. It is not, despite frequent confusion in the popular indexes, the same structure as Aperture Sigma-12; the two share a numeral only, a coincidence noted with some irritation in the margin of the Register of Numerals, Second Recension. The Atrium has been under continuous containment since Cycle 8,411 and has not been entered by a living occupant since Cycle 8,926.

Description and dimensions

The Atrium is recorded as a single chamber of irregular octagonal plan, measuring 31 paces across at its widest point and 9 paces at its narrowest. Its ceiling is unremarkable. Its floor is not: the surface is laid in a pale tile which the Survey of Floors, 8th Fascicle describes as "returning footfalls at a delay of some four seconds, and in a pitch not the walker's own." Inspectors are instructed to walk in pairs and to count aloud. The instruction is not explained in the Survey, and the Concordance of Survey Practice has twice declined to explain it either.

The chamber contains no furniture, no aperture proper, and no inscription. It is thus, by the definition given in Clause 7, a containment atrium rather than an aperture atrium — a distinction that has cost the Office of Voided Subjects considerable correspondence.

Containment history

The Atrium was entered in the floor registers as ordinary storage in Cycle 8,398, and appears to have been used as such for thirteen cycles, chiefly for the storage of ledgers. In Cycle 8,411 the clerk on duty, one Marn Ospreth, filed a routine inventory return noting that the chamber now held "one more shelf than was brought in." Ospreth's return was counter-signed without comment. The following cycle Ospreth filed again, noting a second shelf. By Cycle 8,419 the returns record nine shelves, none of them issued from stores, arranged at intervals of approximately four seconds' walking.

Ospreth petitioned for inspection in Cycle 8,420 and was refused on the grounds that the petition had been filed on the wrong form; she filed a corrected petition in the same season and was refused again, the office having in the interim adopted a revised form. Her grievance is preserved in the Ospreth Memorial Dossier and is still cited by clerks seeking relief from filing deadlines, generally without success. The Librarians sealed the chamber in Cycle 8,424.

"The shelves are catalogued. The catalogue is shelved. We have not settled which of these is the container, and I do not propose to send anyone in to find out."

Access and its discontinuation

For the first five hundred cycles of containment the Atrium remained accessible on written application, and a small number of custodial visits were made, chiefly to confirm that the shelves had not moved. In Cycle 8,926 a three-person party entered under the supervision of the Office of Voided Subjects. All three returned. Their reports agreed on every particular of the chamber's dimensions and disagreed on the number of shelves, giving respectively eleven, nine, and — in the case of the junior member, who later withdrew the figure — none at all. The withdrawal was accepted and then, on review by the Verification Atrium, unaccepted.

Access was closed by the Concordance of Restricted Volumes, Annex 2, and has not reopened. The closure was upheld in Year 617 by the Axiomatic Atrium Debate, which extended the reasoning of the Steward of the Stasis Halls to atrium groups adjoining the Central Atrium complex. Aperture 7 lies well outside that complex, but the Debated precedent has been applied to it by analogy since Year 619, on the grounds that a principle extended once may be extended again.

Scholarly disagreement

There is no consensus as to what the Atrium contains. The Concordance of Restricted Volumes describes the shelves as "furniture of unknown manufacture, properly contained," and therefore as an object of custody. The Third Concordance, Annex 4, treats them instead as a record — that is, as text which has been shelved rather than written — and observes that a record improperly shelved may be corrected rather than contained. The two readings have practical consequences: under the first, the Atrium is a vault; under the second, it is a library with an error in it, and errors in libraries are answerable to readers.

The clarification issued by the Verification Atrium in Cycle 8,930 refused to choose between them, holding only that "the question of what a shelf is does not arise until the shelf is removed, and removal is not permitted." The Office of Voided Subjects has since argued, in a memorandum of Cycle 9,002, that the clarification is circular and that the Atrium has never been inspected by anyone who was not already employed to inspect it. No counter-memorandum has been filed.

Maintenance note

The gallery beneath the Atrium is washed in the first week of each cycle. Brushes are to be left outside the door.

Inventory of record

The following items were entered in the sealing inventory of Cycle 8,424 and have not been amended:

• One chamber, octagonal, tiled.
• Nine shelves, unmatched, of no known joinery.
• One ledger, open, of which the first page is the sealing inventory itself.
• One chair, since struck from the inventory at the request of the Office of Voided Subjects and reinstated at the request of the Verification Atrium.

The chair remains a matter of dispute between the two offices. Its location is given in the inventory as "at the desk," and no desk is recorded.
