THE TIMELINE ATLAS
JOURNEY ATLAS ↗FORM / ROUTE / BOUND
1398 REVIEWED EVENTSLANGUAGE
IN TIME.
One cross-word chronology for every defensibly bounded form and journey stage—without converting a vague historical label into a fake year.
A reviewed graph bound, not a claim of an earliest human word.
Only stages with directly cited numeric bounds enter this atlas.
Labels remain visible in Journey Atlas, but not parsed into false years.

FILTER THE CHRONOLOGY
WHEN DID THE EVIDENCE LAND?
TWO CLOCKS.
NO FALSE PRECISION.
FORM CHRONOLOGY dates a canonical linguistic form or reconstruction in the lexical graph.
ROUTE CHRONOLOGY dates a geographic or transmission stage in a word’s journey.
They can share an era band, but they are never silently treated as the same kind of claim.

Ancient Greek record
Prologos combines a before element with logos for the opening speech before the chorus.
2 EVIDENCE LINKS
The broad interval locates the reviewed Greek theatrical and lexical horizon rather than one first performance.

Latin antiquity and Late Latin
Latin prologus carries the Greek theatrical preface into Latin literature.

The interval locates the Latin transmission horizon, not a single borrowing event.

Prologue broadens from an opening speech to introductory sections and preceding events.

The open interval begins with the reported English horizon and does not claim uniform global adoption.

Anglo-French prologue enters Middle English as prolog.

The interval encodes the lexicographic century report rather than an exact first object.
AUDIT RECORD ↗UNBOUNDED IS
A REAL RESULT.
Stages without source-backed numeric bounds stay in their complete Journey Atlas route, carry an explicit temporal note, and remain absent here until the evidence supports normalization. The missing point is visible work—not permission to guess.
