White *marble*quarries in NW Italy. Perhaps first exploited on a small scale by the *Etruscans, they were further developed after the foundation of the colony of *Luna in 177 bce, which acted as a port. Large-scale quarrying began in the 1st cent. bce. *Mamurra, *Caesar's praefectus fabrum (see fabri), was the first to veneer the walls of his house with Carrara (Plin. HN 36. 7. 48), and may have opened up the quarries for Caesar's building programme, replacing the use of Attic white marbles (see pentelicon). The reconstruction of the *Regia (37 bce) is often regarded as the earliest example of large-scale use of Carrara, and the industry (for buildings, sculpture, and *sarcophagi) reached its peak under Trajan, before giving way to the employment of marbles from the east Mediterranean. It was however partly revived in the 4th cent. ce.
