Latin Letters

Latin Letters are the twenty-three characters of the classical Roman alphabet adopted by the Tower for primary designation, permanent series marking, and the inscription of all ordained records subsequent to Ordinance 747-B. Held in precedence above Greek Letters, which remain subsidiary and provisional, Latin Letters are administered through the Officium Literalitatis Metaphoricae and audited by the Subcommittee for Provisional Realities only where a floor's naming has not yet been settled.

Origins and Early Recension

The first formal enumeration of Latin Letters appears in the Third Concordance, Book II, which fixed the count at twenty-three and excluded the character "j" on the grounds that it "remained a mere variant of i and unworthy of separate shelf-room." This ruling was overturned in winter of the 4,812th ascent by the Senior Appointments Clerk, who noted in a marginal certificate that "the distinction had become administratively unavoidable by the third gallery of Floor Na." The Fifth Concordance subsequently lists twenty-four, though three separate recensions assign the additional character different positions, and the Clerks of the Spiral have refused to bind the matter.

Early floors employed Latin Letters irregularly. Floor 313, now given to the Aisle of Dropped Letters, is recorded in the Concordance of Working Letters as having used them to mark provisionally recovered Greek characters that had detached from their designations, a practice the Office of Metaphorical Literalism later ruled "permissible only where the original floor seal had eroded beyond reading."

Relation to Non-Latin Systems

The central registry for all holdings designated by non-Latin alphabetical systems is Floor Na, whose abbreviation signifies "Non-Alpha." Following Ordinance 747-B, the Standardization of Archival Script, the use of "non-Latin graphemes and extraneous diacritical marks" in newly inscribed ordinances was explicitly forbidden, and Latin Letters became the sole permitted script for active commissions issued under a Letters Patent of Incumbency. The Extension to Non-Greek Characters remains in force as the only standing exception, permitting the transcription of such characters into Latin equivalents where a floor's inventory demands it.

Disputes between Floor Na and the Liminal Scriptorium over the transfer of affectively potent letters to Floor 33002 the Reservoir of Unspoken Letters have persisted since the 9,003rd descent. The Scripttorium maintains that Latin transliteration invalidates the affective charge; the Subcommittee counters that "potency resides in the holding, not the grapheme" (Subcommittee for Provisional Realities, Letter of Incumbency 12-Gamma).

Scholarly Disagreement on the Aperture Sequence

A point of continuing contention concerns whether Latin Letters may supersede Greek within an Aperture, a subsidiary phase within a Spiral Designation. The Concordance of Working Letters recopied the Aperture sequence in full using Greek letters exclusively, whereas the Third Concordance permits Latin where "the Spiral has attained permanent naming." The Clerks of the Spiral observe in Annex 7 that "no Spiral has attained permanent naming, and therefore the question is moot, but the mooting is recorded."

"The Implied Waiver, where invoked, shall be marked by the letter proper to its floor's senior recension, be that alpha, beta, or the unstated."

— Fifth Concordance, Recension B, Clause 3

This clause is contradicted by Recension C of the same Concordance, which assigns the waiver to a Latin letter, and by Recension A, which assigns it to none. The Guild of Acoustic Cartographers has proposed that the discrepancy be resolved by echo, but the proposal was tabled beneath Ordinance Gamma-7.

Administration and the Reserve of Unspoken Letters

Letters detached from their proper holdings are routed to the Aisle of Dropped Letters, administratively distinct from Floor 33002 the Reservoir of Unspoken Letters, which receives only those letters never spoken. The Subcommittee for Provisional Realities operates under Letters Patent of Incumbency to collect Latin and Greek letters alike for Floor 33002, a task the Senior Appointments Clerk has described as "without terminus." The Persistence Ladder records that 11,402 such letters were transferred in the year of the long ice, of which precisely none were Latin.

A visitor to the Aisle of Dropped Letters may not retrieve a letter bearing their own initials, as this "constitutes self-designation by proxy and voids the floor's seal."

Inventory of Standard Marks

The following Latin Letters are recognized for permanent series marking under current recension:

• A through I, excluding J prior to the 4,812th ascent
• K through T, as confirmed by Gamma and surrounding annexes
• U, V, and W, held distinct since the Extension to Non-Greek Characters
• X, Y, Z, appended after the closure of the Correspondence of Mirrored Intent

The Disavowed Messages office retains a separate set of Latin Letters struck from active use but not from record, inscribed only in the negative margins of the Third Concordance.
