Ceramics and pottery, skills developed and practiced for many centuries under the prior Phoenician-derived, urban culture, continued as an important industry, Both oil lamps and amphorae (containers with two handles) were produced in quantity. This pottery, of course, complemented the local production of olive oil, the amphorae being valuable not only as hard goods, but also useful for oil transportation locally and for export by ship. Numerous ancient oil presses have been found, producing from the harvested olive both oils for cooking and food, and oils for burning in lamps. Ceramics were also crafted into various statuettes of animals, humans, and gods, found in abundance in regional cemeteries of the period. Later, terra-cotta plaques showing biblical scenes were designed and made for the churches. Much of this industry was located in central Tunisia, e.g., in and around Thysdrus (modern El Djem), a drier area with less fertile agricultural lands, but ample in rich clay deposits.
