While the Letter Held the Clock

Pliny wrote what he saw — August, year seventy-nine, give or take the month historians still argue. A nephew's letter. Enough date to pin a mountain.

Marzoli lifted the sanidine in ninety-eight; it sat unused for decades in a drawer while the sentence kept holding the clock.

Berkeley and Padua finally set argon against that letter — one thousand nine hundred thirty-eight years before twenty twenty-five, thirteen years of play. Potassium's half-life tightened in the bargain.

Pompeii tourism. Better mass specs. Benchmark. Those mouths arrive late, once argon agreed. Looking stops earlier — on the sentence already holding the clock while the rock waited.

Leftover is both. I take the sentence: the drawer is still half about delay; the letter was already a date before anyone called it a benchmark.
