The year lattice

One room per year: how the year is counted in each ancient reckoning (Olympiad, archon), where the served record dates itself, what the record ties to the same time — and, leading, where the calendars part. The desk states what the table and the record STATE; where they disagree, it serves the fork, never a verdict. receipt — the chronology desk

The lattice holds 12 poured years — 490 BCE to 479 BCE, the Persian-war corridor. Clinton’s tables on the shelf reach far beyond it (Fasti Hellenici to the death of Augustus; Fasti Romani beyond); those rungs await their waves. A year missing here is a fact about the desk, not about time.
