In 2020, a man of seventy-three, working from a house on a quiet street in a suburb west of Munich, published a book that was not his — the last chapter of somebody else's history of the world, missing for eighty years since the author stopped writing. He had spent four decades editing that author. Then he found the ending that was not there, set it in type, and sent it out. His name is Heribert Illig, and he is the reason there are sincere people who will tell you the year is not what you think it is. Tonight is a claim that three hundred years of history never happened — that the years between 614 and 911 are empty, that Charlemagne is largely a fiction, and that we are all living in a year with the wrong number on it. It is one of the strangest things anyone has argued in print, and it was argued carefully, by people who meant it. We take the claim at full strength first, the way its makers actually made it: a table in Vienna in 1990, a bottle of white wine, and an arithmetic that seems to show three days unaccounted for in the calendar — three days that, at the rate the old calendar drifted, come to three centuries. Then the society that produced it: about fifty people, a photocopied bulletin, a treasurer's widow keeping the accounts. And the real congress about medieval forgery that convinced its founder such a thing was possible — because the ninth century truly did manufacture nearly a hundred false papal letters, and they fooled Europe for seven hundred years. Then the answer, from four directions the theory never looked. The document it is built on, read properly — a single subordinate clause in the papal bull of 1582 that names what it is correcting, and it is not Julius Caesar. A friar in 1267 who measured the drifting sky with crude instruments and got the number only unbroken years can give. Three calendar corrections — Catholic, Protestant, and Bolshevik — made by parties who agreed on nothing else, each landing exactly where the arithmetic requires. And a government office in the Chinese capital that logged eclipses and comets through the empire's worst civil war, whose entry for the fifth of August, 761 still checks out four separate ways today. And finally the trees: a storm on the sun in the summer of 774 that marked itself in wood on five continents, in coral, and in Antarctic ice — a mark in a year that, on this theory, nobody lived through. Two endings, side by side, no verdict. Because they were wrong about the years — and right that somebody ought to check. A calm, unhurried telling for sleep, rest, or a long drive in the dark. Nothing here will startle you or wake you. LANTERN & LEDGER — quiet tellings of the record, for sleep.
