Roman amphorae were wheel-thrown terracotta containers. The Romans turned the Greek form into a standard -a declension noun, "amphora", pl. "amphorae". These wines were stored in sealed earthenware amphorae and kept for many years. The pottery imports consisted of "terra sigillata", amphorae, glazed pottery, and stamped white pottery. Panathenaic amphorae, now a frozen tradition, were the only large painted vases still made. In addition, they found Greek arrowheads, slingshots, ballistic stones and amphorae. Once fermented, wine was transferred to wineskins or large amphorae for storage. Those people carried in their vessels silver ingots, gold ingots and amphorae. On wrecks A-C, mounds of distinctive carrot-shaped shipping jars, called amphorae, were found. Grave gifts include the typical globular amphorae and stone axes. Versions of the amphorae were one of many shapes used in Ancient Greek vase painting. Wooden and skin containers seem to have supplanted amphorae thereafter. Large "krater" and "amphorae" became popular at this time. At a later period, paintings on some "amphorae" depict winged centaurs. Fifty amphorae, used to contain wine and oil, were seen spread nearby.
