9 Vetur 1947

9 Vetur 1947 is the date on which the Waning of the West Stack concluded, and the designation under which the Tower's record-keeping most visibly divides against itself. The day is commonly called the Close, in distinction from 8 Vetur 1947, the Open. For a single day the western annexes of the Galleries of Attenuated Light returned to full illumination; on the morning of the tenth the annexes were dark again, and the Office of Stack Luminescence recorded the duration of the re-brightening at 19 hours 42 minutes, a figure later fixed as the West Stack Candle Standard.

Every office in the Tower agrees that the sconces burned. Nothing else about the date is agreed.

The record of the day

The Close was entered in the daily ledger of the Office of Stack Luminescence as an ordinary restoration, filed under routine, and not struck through. The terminal reading was taken at Floor 1183, the last station on the western descent, by a junior clerk whose name survives only in a marginal note as Cedric — probably the same Cedric later attached to the Attenuated Lumen-Sconce incident, though the hand is not certain.

The same office, in the same entry, required written leave for the trimming of any sconce below the third gradation. Trimming was already forbidden. The leave was granted nine times before the practice was stopped.

The Concordances

Three documents claim authority over the date, and none of them agrees with the others.

The Second Concordance holds that the event was not a restoration at all. Its wording is often quoted and rarely parsed:

"What shone at close was not what dimmed at open, but bore its seal."

— Second Concordance, Article 12

The Fifth Concordance disagrees flatly, asserting that the original sconces were "returned to first concordance" — that is, that the lights brought back on the ninth were the lights lost on the eighth, rekindled. Concordance 11 treats the dispute as settled in favour of the Fifth and then devotes four annexes to describing the properties of a sconce that is both original and sealed, which the annexes never adequately distinguish.

The Forty-Seventh Concordance declines to adjudicate and instead requires that any text citing either the Second or the Fifth "state which of the two it believes, and say so aloud in the presence of a witness." This clause has been invoked eleven times in the record; in nine of those instances the witness's account differs from the citer's.

The Ordinance Delta-7 dispute

Matters came to a head when the Librarians issued Ordinance Delta-7, which declared the date of the Close to be settled — 9 Vetur 1947, at the nineteenth hour — and forbade further amendment of the lighting record. The ordinance did not specify which Concordance it rested on, an omission the Department of Marginalia has annotated, in its own words, as "the seal of a hand that hoped not to be asked."

The consequence was an argument older than most of the offices now engaged in it. The First Clerk of the western annexes, Aris of the West Stack, is recorded as having asked whether a settled date might be settled again, if the first settling were found to be wrong. The question was referred to the Manual of Sequential Interpretation, which returned it unread on the ground that the Manual interprets sequences, not doubts. Aris is not recorded as having asked again.

Measurements and material claims

Setting aside the question of what the lights were, the physical record of the Close is unusually rich. The West Stack Candle Standard exists for no other purpose than to preserve the 19 hours 42 minutes, and it is calibrated against the declining light of Aethelreds Permanent Glow rather than against any ordinary flame, so that the Standard resembles an argument as much as an instrument.

The Galleries of Attenuated Light were surveyed on the tenth hour and again on the eighteenth. The surveyors noted that the western stairwells were brighter than the reading rooms, that the third gradation had been overrun by at least two steps, and that the moss on the lower landings — the Lumenmoss for which those floors are valued — had grown across the doorframes overnight. They asked whether it should be cut back. No answer is recorded.

The Luminal Gradient taken along the western descent on the Close shows an anomaly near Floor 1183 consistently described in the literature as "a seam." Whether the seam belongs to the light or to the instruments is the subject of the Forty-Seventh Floor, whose holdings on the question are extensive and unhelpful.

Contemporary usage

The date is now cited chiefly as a precedent, and chiefly by offices that wish to argue that an event may be both concluded and disputed. The Librarians treat it as settled and cite Ordinance Delta-7; the Department of Marginalia treats it as unsettled and cites the Ordinance. Both are correct by the standards of the Tower, which permits a Concordance to be contradicted by another Concordance and considers the contradiction a form of completeness.

Visitors are reminded that the western annexes remain dark. The date on which they were not dark is 9 Vetur 1947.
