Six glyphs deep

Claim (verbatim)

Zapotec writing is the longest-lived script tradition of ancient Mesoamerica — inscribed monuments at Monte Albán and across its region run from around 500 BCE deep into the first millennium CE — and it remains undeciphered while Maya, a younger script, is read. The corpus of record is Javier Urcid's Zapotec Hieroglyphic Writing (Dumbarton Oaks, 2001), which assembles several hundred inscribed monuments: some three hundred danzante slabs with brief captions, roughly forty 'conquest slabs' from Building J, and the later genealogical registers. The blocking fact is not corpus size but text length: Zapotec inscriptions are overwhelmingly calendric names, place signs, and short labels — strings too short to expose syntax, and without syntax no grammatical decipherment can bootstrap, whatever the method. The mechanism is a genre allocation that starved the durable record: a two-millennium literate tradition's long-form registers ran on perishable media, while stone received names and labels. Zapotec is thus the inverse of the epi-Olmec case — many objects and no long texts, against two long texts and little else — and the two failures bracket one law: decipherability tracks the survival of long strings, not the count of inscribed objects. The lost majority here is not the monuments; it is the syntax, which lived on materials that rot. Prediction: in Urcid's corpus catalogue, the median inscription length will fall below ten glyphs, no inscription will reach one hundred glyphs, and fewer than 5% will exceed thirty, while the catalogued object count exceeds two hundred — an object corpus more than tenfold epi-Olmec's carrying no text a quarter the length of La Mojarra's (primary clause: the median-below-ten with zero-at-one-hundred length census; the verdict follows it). Kill: Javier Urcid, Zapotec Hieroglyphic Writing (Studies in Pre-Columbian Art and Archaeology 34, Dumbarton Oaks, 2001), corpus catalogue, with Alfonso Caso's Monte Albán monument studies as control.

Novelty / leakage triage

already answered in the literature

That Zapotec inscriptions are overwhelmingly short — calendric names, place signs and brief captions, with no long syntax-bearing texts — is the field's standard, load-bearing explanation for why the longest-lived Mesoamerican script remains undeciphered, stated by Urcid's corpus study and by Marcus. The primary clause's core (no inscription reaching one hundred glyphs, a median far below ten, across an object corpus in the hundreds) is guaranteed by the known composition of the Monte Alban danzante and Building J material against the later genealogical registers. Only the exact median and percentile figures are uncomputed; the answer that the durable record carries names and labels but not syntax is in print.
