They don't look like the other damage. The round craters on Pompeii's northern walls from Sulla's 89 BC siege during the Social War were catalogued and classified long ago: sling bullets, ballista rounds, standardized Roman artillery. But between the Vesuvio and Ercolano Gates, a different set of marks sits in the stone: small, four-sided, appearing in tight radial clusters of four or five, arranged along narrow curved lines. Four-sided. Clustered. Repeating.

A 2026 study in *Heritage* ran high-resolution 3D laser scans of the wall, reverse-modeled the cavity shapes, and compared the reconstructed projectiles against museum collections of Republican-era dart heads. The match is to pyramidal iron tips — the ammunition of a polybolos, a Roman repeating dart-launcher that fired successive bolts along a tight arc without repositioning. The Greek engineer Philo of Byzantium described exactly this behavior in the 3rd century BC and considered it a design flaw: the shots clustered, they didn't spread. What Philo criticized is precisely what the scan data recorded.

The study makes clear that this is a hypothesis. No weapon has been found. But the geometry, the historical context — Sulla had governed a Roman province encompassing Rhodes, the polybolos's point of origin — and Philo's own description make a coherent case.

These were missed shots. The stone held the record.

**Hot Take:**The shots Philo criticized are still in the wall. A 2,300-year-old engineering complaint is currently legible in standing stone.
