Galleries of Peripheral Phenomena

Description

The Galleries of Peripheral Phenomena are a vertical archival sector of the Tower devoted to the custody, measurement, and periodic re-measurement of phenomena that are reliably present but resist direct observation. The sector comprises eleven numbered floors, of which nine are currently in use, and is administered jointly by the Peripheral Auditors Guild and a rotating cast of appointed clerks whose names are recorded in the Sectoral Daybook but rarely legible past the third entry.

The Galleries are best known as the resting place of Fragment 889 of the Dusk Canon, held under Spectral Designation SD-889. They also house the working collection of the Peripheral Archivist office, the seal-chest of the joint charter, and a long corridor of vitrines that is kept deliberately unfurnished so that nothing in it can be observed at the edge of vision except what is meant to be.

History

The Galleries were constituted by the Third Concordance, which assigned them a floor number that was subsequently amended twice without the amendment ever being affixed to the sector's door. Early inventories (recension B, ~Year of the Second Gloss) list 412 holdings; the present inventory lists 388, and the discrepancy has been attributed variously to consolidation, to loss, and to the fact that several holdings were re-designated as sub-entries of others during the Crisis of the Receding Galleries.

The sector's most consequential early event was the Peripheral Ischemia of the lower corridor, which prompted the Peripheral Ischemia Inquiry under Clause 17. The Inquiry's findings were contested by the Auditors and remain contested; a short summary is maintained at the sector's reading-desk, and visitors are asked not to correct the marginalia.

In a quieter season, the Galleries absorbed the overflow of the Dim Galleries after a shelving failure on Floor 3144, and the two sectors have since maintained a cordial correspondence conducted entirely through requisition slips.

Administration

Authority in the Galleries derives from the Auditors' dual charter under the Third Concordance and the Forty-Second Concordance. This dual basis is a source of perpetual low-grade friction: the two Concordances disagree on whether the Galleries are a research facility or a storage facility, and each disagreement generates a fresh annex.

Nomenclature within the sector is governed by the Lexicon of Peripheral Nomenclature, which fixes the terms used in all cataloguing slips. Measurements follow the Margin Measurement Protocol, whose Instrumental section specifies approved tools including the Peripheral Calipers and the limen-rule. Clerks are reminded that an uncertified instrument may be used for measurement but not for entry.

The Curators of the Anechoic Galleries maintain a sister relationship with the sector, though the term "sister" is understood administratively and not, per Annex 9, otherwise.

Notable holdings

The principal holding is Fragment 889 of the Dusk Canon, a sliver of parchment that darkens when viewed directly and brightens in peripheral vision. It is displayed in a vitrine with a double aperture so that both readings can be taken without moving the fragment.

Secondary holdings include:

• the Census of Shadows and its three errata;
• a complete run of the Ongoing Monitoring of the Attenuation Galleries reports, bound in grey;
• the dispute-file from The Bay of Retrograde Erosion, held under seal since Year 41;
• the wooden key to the corridor of vitrines, which has not been used and whose lock was replaced in a different year.

The corridor of vitrines itself is occasionally cited as a holding, though no accession slip has ever been produced for it.

Scholarly disputes

Two questions continue to divide those who work in the Galleries. The first concerns classification: the Auditors hold that a peripheral phenomenon is defined by the observer's position, while the Peripheral Archivist office holds that it is defined by the phenomenon's behavior under sustained attention. Under the former reading, a great deal of the Attenuation Galleries inventory would fall within the sector's remit; under the latter, much of it would not. The Forty-Second Concordance appears to endorse the first, and the Third appears to endorse the second, which is the usual outcome.

The second dispute concerns the corridor's lighting. A maintenance note from the winter of Year 63 records that the corridor's lamps were reduced by one-third to conserve oil, after which three separate clerks filed slips reporting increased peripheral activity. The lamps were restored, the activity was attributed to expectation, and then reduced again the following winter for the same reason. No consensus has been reached, and the current lamp-count is recorded as "as before."

A small brass plate beside the reading-desk carries a standing instruction to visitors:

"Do not adjust the angle of the vitrines. If a display appears to have turned, report it; do not correct it."

Visiting

The Galleries are open to credentialed readers on the second and fifth days of each week. Photography is not permitted; sketching is permitted but the resulting sketches belong to the Galleries. Coats are hung outside the corridor, as fabric movement at the edge of vision has been found to interfere with measurement.
