Keeper Armitage

The Keeper Armitage is the honorific and office attached to the Librarian whose rulings on the Spengler Resonator are cited in no fewer than four hundred separate disputes annually, most of them by parties who have not read them. The office is not hereditary, not elected, and not, strictly speaking, currently occupied; the rulings continue to circulate regardless. Keeper Armitage is remembered chiefly for a single year of activity — 1597 — during which the calibration protocols of the Resonator were amended twice, restored once, and subjected to a debunking that has since been cited in support of three mutually exclusive positions.

The 1597 Rulings

The fame of Keeper Armitage rests on three instruments issued in the same year, in an order that remains contested. The first amended the calibration protocols for the Spengler Resonator, inserting a requirement that any reading taken during assessment be accompanied by a note of the hour and of the Unspoken components then in play. The second and best known establishes the tuning standard:

"The Resonator shall be tuned, during assessment and during assessment only, to the hum of the archival air-scrubbers on Floor 14,301, and to nothing else, however sweet."

— Keeper Armitage, Ruling of 1597, Instrument ii, clause 3

The third is the debunking. In the same year Keeper Armitage ruled against the so-called Linus Compression — the claim, advanced by a faction of the Resonator's custodians, that the Resonator's hum could be compressed into a shorter hum without loss of archival meaning. Keeper Armitage found that compression preserved the frequency but discarded the meaning, which resides in the duration, and ordered the theory struck from the calibration register. The ruling has been appealed every year since without once being heard.

The Dispute with the Keeper of Paradoxes

The tuning standard of Instrument ii brought Keeper Armitage into prolonged conflict with Keeper Linus, then Keeper of Paradoxes and later Keeper of the Spiral. Linus held that a hum tuned to a single floor's scrubbers was a hum that could not be tuned to any other floor, and that a Resonator so tuned could not travel — which, Linus argued, made it not a Resonator but a fixture. Keeper Armitage's reply, recorded in the Office of the Keeper of Precedents and much quoted at the time, was that a Resonator which could travel anywhere could be trusted nowhere. The two offices exchanged instruments for the better part of a decade. The matter was eventually absorbed into the wider jurisdictional quarrel between the Spiral and the Resonator's custodians, and has never been formally resolved; it is simply no longer raised in writing.

The Scrubber Census of 1201

Instrument ii depends entirely on the hum of the air-scrubbers on Floor 14,301, an arrangement that functioned undisturbed for six centuries and then failed in the winter of 1201, when the scrubbers on that floor were taken down for bearing replacement and the Resonator was left without a tuning reference for nineteen days. Clerks of the period record that assessments were simply not taken. A minority record that they were taken and tuned to the hum of a nearby ladder-gantry, and that this accounts for the anomalous measurements of the period. The question was put to Keeper Theodosia upon her appointment as First Keeper in 1203, who declined to rule, observing that the ladder-gantry had been removed in the interim and could not now be examined.

Since the census, Instrument ii has been read as permitting substitution of the nearest scrubber of equivalent pitch. No instrument says this. It is done anyway.

Attribution and the Recensions

Scholarship divides on whether the three 1597 instruments belong to one Librarian. The Third Concordance and the Ninth Concordance give different account: the Third treats the tuning standard and the debunking as the work of a single Keeper, while the Ninth, Annex 4, assigns the calibration amendment to "the Keeper Armitage of that year" and the debunking to "the Keeper Armitage then serving," which its marginalia glosses as two persons of the same name. No register survives to settle it. The Office of Precedents maintains the single-Keeper reading; the Archive of Provisional Holdings files both, on the ground that the question may yet be reopened.

Protocol of the Empty Chair

The office itself is listed as dormant. Its rulings nonetheless bind, and are cited by parties on floors where Keeper Armitage never set foot, in disputes concerning pitch, duration, and the naming of hums. A chair is maintained for the Keeper in the assessment chamber adjoining Floor 14,301. It is kept dusted and is not sat in. Petitions left upon it are collected quarterly by the Office of the Keeper of Temporary Jurisdictions and answered in the negative, on the authority of Keeper Armitage, which is considered sufficient.

Visitors to the chamber are asked to speak softly, as the scrubbers are running.
