Our knowledge concerning the population of the territory of Dorgali during the Medieval Age is very limited, mainly because of the total lack of excavations in specific contexts.

The available evidence related to this Culture’s material come almost exclusively from the reuse during the Middle Ages of some natural caves, such as that of Sos Sirios, a small cave overlooking the Codula of Luna, in use since the Nuraghic Age.

Throughout the karst area of Supramonte, it is quite common to find evidence inside the caves, related mainly to the funeral rites of the ancient inhabitants of Sardinia. Among the artefacts found in the latter, the presence of an amphora of the so-called "common ceramic with a slip casting decoration" and/or "from the Campidano region" is significant (fig. 1); this is a type of tableware object which is not found outside Sardinia and which appears to be mainly concentrated in areas close to Cagliari and partly in the Oristano region.

The small amphora from Dorgali is a vessel with a closed shape with two handles, used to transport and store liquids. Its body is short, wide and flat and with a high cylindrical neck. It is a locally produced ceramic whose colour ranges between red and brown, slip decorated.  Based on comparisons with similar artefacts from other Sardinian contexts, such as in the necropolis of Pill'e Matta in the area of Quartucciu (figs. 2, 3, 4, 5, 6) and near the Church of St. Eulalia in Cagliari, this ceramic artefact of Dorgali may be dated to a period when this type of pottery was widespread, i.e. between the third-fourth and seventh centuries A.D.

The artefact is on display in the Archaeological Museum of Dorgali.
