A Bronze Ball Counted Each Roman Mile

A traveller did not have to stop, look back or ask how far the chariot had gone. In Vitruvius’s design, the vehicle answered with a sound from inside its own body. One small ball fell through a channel and struck a bronze vessel. The noise marked a mile. At day’s end, the balls collected below … Read more

Hooves, Flint and Wind Separated a Roman Harvest

The grain reached the farmyard still fastened to ears, mixed with straw and vulnerable to a change in the sky. It left as heavy kernels gathered in baskets.

Four Letters Let Cicero Escape Pompey’s Grammar Trap

Pompey had conquered armies, crossed seas and accumulated honours. Four letters on a theatre still presented a problem he did not want to decide alone.

A Roman pantry could not be defined simply by opening a door and naming what stood inside. Aulus Gellius records a conversation in the entrance hall of the imperial palace on the Palatine.

A Rhetoric Teacher Stopped Senators in Holiday Slippers

The rhetoric lesson began after the students had left their formal clothes behind. Aulus Gellius says his teacher Titus Castricius encountered several pupils who had become senators.

Sold Loot Paid for the Gilded Horses Above Trajan’s Forum

The gilded horses above Trajan’s Forum were not trophies lifted whole from an enemy city. Their inscription pointed to a less visible route.

Eleven Copies Hid the Shield That Fell from the Sky

Rome protected one sacred shield by making it impossible to tell which shield was sacred. Plutarch says a bronze buckler fell from the sky during a pestilence in Numa’s reign.
