“…The importation of Proconnesian marble to Italy began in the Flavian period with Hadrian, and in the third century AD its level of distribution increased dramatically, especially in Rome, replacing the marble of Luni (Pensabene , 574; Pensabene and Domingo , 125), because, as attested by Diocletian's Edictum de pretiis , it was one of the cheapest marbles (Giacchero , 210–11; Barresi , 166). This was due perhaps to the efficient organization of the export and distribution, which were probably controlled, if perhaps not completely (see Russell's opinion of partial private ownership of the quarries: Russell , 55, 59, 357–9), by the Emperor (Pensabene , 205), and also thanks to the large size and location of the quarries close to the coast. On the other hand, Dokimean marble, although it was also probably extracted from quarries controlled by the state (Hirt , 116; Pensabene , 366–9), was one of the most expensive marbles, both because of its quality and because of its distance from the sea (Giacchero , 210–11; Ward‐Perkins , 329; Barresi , 166; Pensabene , 215).…”
