pecorino

The Latin word pecus named any herd animal, but Roman agricultural writers gradually narrowed its meaning toward sheep in particular. Columella, writing around 65 CE in De Re Rustica, used the adjective pecorinus for products belonging to sheep. The Italian diminutive suffix -ino arrived centuries later as spoken Latin hardened into a new language. By the medieval period, pecorino named both the animal's quality and the firm cheese pressed from its milk.

Pliny the Elder noted in 77 CE that a salty, dense cheese from the hills near Rome survived long military campaigns across North Africa and the Levant. That cheese was almost certainly an ancestor of Pecorino Romano, though Pliny described it by location rather than by animal. Shepherds in Lazio had been pressing sheep's milk wheels for at least two thousand years before anyone wrote the word down. The salt content was practical: it preserved protein across months of transport.

Sardinia became the dominant production center after Rome's population collapsed in the early medieval centuries. The island's rocky pastures suited sheep herding far better than cattle ranching, and Sardinian shippers exported tens of thousands of wheels annually by the 16th century. The Italian government formally recognized Pecorino Romano as a defined regional product in 1884, the first Italian cheese to receive state protection. That act fixed a category that had been understood informally for nearly two millennia.

The modern word pecorino names a family of cheeses: Romano, Sardo, Toscano, Siciliano, each with its own pastures and aging times. All trace their name to pecora, Italian for sheep. The word gives no information about geography or aging; it gives only the animal. That directness is the whole etymology: in this name, the sheep is the entire story.
