| Abstract: | A Greek merchant ship carrying a cargo of millstones, amphorae and bronze vessels was wrecked at Sec, off Mallorca, Spain. in about 375-350 BC. Geochemical provenancing of the millstones helps in reconstructing the route of the ship and complements evidence from the amphorae. Thirty-eight lava hopper-rubber millstones and one Pompeian-style rotary mill from the ship were sampled for provenancing. The hopper-rubbers are mainly of basalt from the island of Pantelleria off North Africa in the Sicilian channel, one is from Nisyros off the Anatolian coast, and the Pompeian mill is of ignimbrite from Mulargia in Sardinia. The hopper-rubbers are the most westerly examples known in the Mediterranean. and the Nisyros mill represents the first proven instance of millstone transport between the east and the west Mediterranean. The occurrence of the Pompeian mill in a fourth-ceniury BC context is evidence of the use of this type a century earlier than previously thought. The Nisyros mill was probably taken on board at the start of the ship's voyage in the eastern Mediterranean, the Pantellerian mills may have been collected partly as ballast at Pantelleria, and the Mulargia mill was probably picked up at Carthage. |
