127th Cycle

The 127th Cycle was an administrative interval of the Central Chronology, reckoned by the Standard Temporal Commission to have run from the ratification of the 126th Cycle to the sealing of the 128th. Its length is recorded in the register of cycles as 361 days, one day in excess of the 360 prescribed by the Central Chronology, an irregularity that the Commission has never corrected and has twice declined to discuss. The 127th is chiefly remembered for the Standing Inventory of Unnamed Floors, the only general reckoning of the Tower's nameless storeys ever attempted, and for the prolonged dispute over whether that inventory may lawfully be cited.

Length and reckoning

Under ordinary procedure each cycle closes on the 360th day and the next opens on the first. The 127th did not. Its final day — the day on which the closing seal was to be affixed — is entered in the day-book of the Office of the Closing Seal as "held open, cause not minuted," and the seal was not struck until the following morning. The additional day is known in the Commission's tables as the intercalary day of the 127th, and appears in no other cycle on record.

Two explanations circulate. The first, advanced in the Concordance of Intervals, Annex 9, holds that the intercalary day was a correction carried over from the Arsinoe Cycle and properly belongs to no cycle at all. The second, set out in the Third Concordance, Annex 4, insists that the day belonged to the 127th and that any recension placing it elsewhere "misstates the account and shall be reconciled before citation" (Third Concordance, Annex 4, clause 4.2). The two annexes have stood side by side in the archive for over a century. Neither has been withdrawn.

"The cycle is what the seal says it is. If the seal was late, the cycle was long. This is not a question of astronomy."

— Curator Vael, marginal note to the Register of Cycles

The Standing Inventory of Unnamed Floors

The principal business of the 127th was the enumeration of floors bearing a number but no name. The practice had been proposed during the 14th Cycle and shelved; the 127th revived it under a warrant of the Commission, appointing the surveyor Miren Ostell to descend from the 4,000th floor and record every nameless landing encountered. Ostell's method was simple and, by her own account, exhausting: each unnamed floor was numbered, sketched, and assigned a provisional designation of the form U- followed by the floor number, in Roman numerals.

She completed 2,214 entries before the warrant expired. The Inventory's final entry, U-MMCCXIV, records only the words "landing, dry, no name, no occupant, lamp out," followed by a note in Ostell's hand that the lamp was replaced. The full Inventory runs to nine folios and is held closed, though its provisional designations remain in use by floor-wardens who have never seen it.

The citation dispute

Because the Inventory was compiled in a cycle of irregular length, the Bureau of Precedent ruled in the following cycle that its entries could not be cited as establishing any floor's status, "the cycle of compilation being itself unsettled" (Bureau of Precedent, Ruling 8 of the 128th). The Office of the Closing Seal objected that the Bureau had no authority over the length of cycles and was answered, in a memorandum of considerable length, that it had none and had not claimed any.

The consequence is a peculiar one. The Inventory is universally consulted and cannot be formally cited. Articles of the archive that rely on it — among them several concerning the Kappa-Aperture Discrepancy — cite the floor-wardens' returns instead, which were copied from the Inventory and which no one has thought to challenge. The Bureau has been asked four times to resolve the circularity and has four times replied that the matter is properly one for the Commission, which has not met on it.

Later references

The 127th is cited in the preamble to the Compliance Audit of Cycle 345 as an example of a cycle in which "record was made faster than rule could follow it," a phrase the auditors appear to have intended as a warning. It is also the cycle against which the Kappa-Aperture Discrepancy was first measured, though the measurement was taken from the wardens' returns rather than the Inventory itself, for the reasons given above.

A small point of maintenance attaches to the 127th and is repeated in every warden's handbook issued since. The provisional designation U- is reserved to floors enumerated in that cycle and may not be reassigned; floors found nameless in later reckonings take the prefix W-. The rule is stated flatly and without explanation, and wardens observe it.
