On Resonant Designations

On Resonant Designations is a treatise by Librarian Third-Class Aris, deposited in the Scriptorium of the Forty-Third Floor and subsequently recopied into the Scriptorium of Designations under seal of the Office of Designations and Epithets. The work sets forth the first systematic account of how designations acquire resonance within the Tower and why certain floors answer to names they were never given.

Provenance and Deposit

The treatise was composed during the long recension of the Master Roll of Active Designations, a period the Bureau of Spatial Designations records as lasting from the 12th day of the Month of Narrow Apertures in the 884th Cycle to the 3rd day of the Month of Lower Ledgers in the 886th Cycle. Librarian Third-Class Aris submitted the original manuscript on pressed reed-fibre, bound with a single length of undyed cord, to the Scriptorium of the Forty-Third Floor. The Guild of Resonant Masons contested the deposit on the grounds that the work touched sub-designations of Tier Alpha, but withdrew the objection after the Bureau of Composite Designations ruled that no solidus appeared in the title and therefore no consultation was required.

Principal Arguments

Librarian Third-Class Aris holds that a designation becomes resonant when it is spoken on three non-adjacent floors within a single descent and is thereafter entered neither in the Principal Register of Designations nor struck from the Grand Taxonomy of Unassigned Designations. The treatise distinguishes resonance from mere echo, citing the failure of the Resonant Cavities to retain the name of the Bureau of Appointments Sub-Division for Provisional Designations on Whisperwood, which Aris attributes to "insufficient downward travel" (On Resonant Designations, Section II, clause 9).

The author further proposes that the Hierarchy of Designations be amended so that grades maintained by the Office of Designations and Epithets acknowledge a secondary order of resonance, to be filed by the Scriptorium of Designations using instruments of re-designation lodged in that office's custody.

Reception and Scholarly Dispute

The Third Concordance acknowledges the treatise as "a useful if incomplete enumeration of acoustic grades" (Third Concordance, Annex 4), whereas the Seventh Concordance declares that "no designation may resonate prior to its elevation of standing in the Principal Register of Designations, and the contrary view is a cataloguing error" (Seventh Concordance, Recension 2, Article 11). The contradiction remains unresolved; the Bureau of Spatial Designations has issued no ruling, on the customary ground that floors and apertures are its charge and grades are not.

A further disagreement concerns the treatise's claim that Resonant Light is the medium by which resonance is verified. The Manual of Resonant Integration asserts instead that verification requires the laying of a Resonant Damping Mesh across the aperture in question, a process the Guild of Resonant Masons oversaw on the 211th Floor during the Winter of the Short Candles.

Subsequent Recensions

Four later office-holders of the rank Librarian Third-Class Aris have appended marginal notes to the deposited copy. The second of these, whose name the Master Roll of Active Designations records only as Clerk Vell, objected that the treatise neglected Resonant Material Interaction with Resonant Argonium, a substance then stored without catalogue on the 57th Floor. Clerk Vell's grievance, entered on the 19th day of the Month of Upper Hinges in the 901st Cycle, was that "the author describes the wall but not what the wall is made of" (Librarian Third-Class Aris, marginalia, folio 12 recto).

Present Holding and Access

The recensed copy is held in the Scriptorium of Designations and may be consulted by any Librarian bearing a seal from the Office of Designations and Epithets. Readers are permitted to copy excerpts provided they do not speak the designation aloud on more than two floors in one ascent.

"A designation that is only written has not yet spoken; a designation that is only spoken has not yet been filed."

The Protocol of Resonant Description makes frequent reference to the treatise, and the Resonant Masonry of the 43rd Floor annex retains a carved extract above the door through which deliveries of reed-fibre are no longer accepted.
