This latest excavation campaign aimed to test the nature of the archaeological remains in the western area of the sanctuary under investigation. Today, this area is slightly sloped, with an increase in the incline towards the west where it reaches a group of large boulders which show evident signs of ancient quarrying . Three trenches were opened, forming a "U" shape, which revealed the existence in situ of structures belonging to the sanctuary and thus the latter's great extension: it was also shown to occupy the terrace above. The first trench, dug in correspondence with the axis of the main entrance to the sanctuary revealed the presence of three walls, orientated N-S, and thus on a slightly different alignment with respect to that found in front of the temple. Found below a collapse was a silver denarius of Quintus Antonius Barbatus (83-82B.C.), which provided useful dating information. A second trench was dug with the aim of understanding the conformation of the plateau in this area at the time of the sanctuary's latest construction phase. Numerous alluvial layers came to light, over 2 metres deep in the area nearest to the already known sanctuary structures; these layers filled the deep rift caused by the great landslide which probably lead to the definitive obliteration of the sanctuary. Collapsed material from the so-called temenos and east wall of room F were found in situ. Above the collapse an antefix of the "Artemis Bendis" type was found, together with a bronze "paragnatide", which probably belonged to a Roman helmet of the "Hagenau" type (1st century B.C.-1st century A.D.), which would have originally hung inside room F. It seems certain that this latter structure would have had some kind of roof and thus it is unlikely that it was simply a boundary wall. (Maria Luisa Nava)

An in-depth study has been undertaken by geologists from CNR at Potenza in the area of the Lucanian sanctuary of Rossano di Vaglio. The primary objective was to get an exact idea of the nature of the land-slippage that has effected the sanctuary's structures and to monitor its movements. As regards the excavation, a trench was opened with the aim of uncovering the remains of a 1st century B.C. wall, probably built to create a terrace in an area where the ground level had been slightly raised. The wall (6m long) cuts levels dating to between the 4th to 3rd century B.C. (a date based on the presence of black glaze ware and Roman bronze as} The remains emerged of a pavement of stone basoli, the same as that which came to light in the area known as the front of the temple, dating to the 1st century B.C. Another trench has shown that the supposed _temenos_ wall incorporating the fountains did not function as a terrace wall in antiquity. It was in fact part of one or more rooms with tiled roofs. A new inscription was found within the wall, incised on a fragmentary sandstone block. On one face is a three line inscription, partially obliterated in the Greek alphabet and Oscan language, which according to the preliminary research undertaken by Paolo Pocetti cannot be earlier than the 3rd century B.C. The text is as follows: (Mefitis) Utianai …pies - t (Ma)mertoi This is probably a dedication to Mefitis Utiana and to Mamaerte made by some person of rank whose name ends in "...PIES". The block had been reused in the wall's construction.

In September 2007 excavations recommenced on the sanctuary at Rossano di Vaglio. The work was directed by Marcello Tagliente for the Archaeological Superintendency of Basilicata, and coordinated by Prof. Emmanuele Curti. At the same time an overall re-examination of the material from the Adamesteanu excavations was carried out under the direction of Prof. Massimo Osanna. The excavation campaign had two main objectives: 1) a more precise definition of the various occupation phases of the complex; 2) to check for the presence of structures relating to the earliest phase of the sanctuary between the 4th and 3rd century B.C., to date only attested by ex voto and inscriptions. The excavation examined the zone of the altar and the central paved area and the area to the south with a series of rooms (II, IV and III). In the first sector, the data seemed to confirm the absence of monumental structures belonging to the earliest phases of the sanctuary and the altar and paved area resulted as almost directly in contact with the natural bedrock which had been simply levelled. In the southern sector, which produced some of the most important finds from the sanctuary (inscriptions, marble statues), the results were as follows: 1) a series of ritual ‘actions’ linked to the phase when the sanctuary was monumentalised were identified 2) the discovery at a greater depth and below the levels of fill and overall reorganisation of the area, of structures relating to the earliest phase of the sanctuary, in particular a great wall in stone blocks. This was either terracing or the substructure of a large building. The emplecton produced materials and coins dating to the end of the 4th century B.C. In synthesis the rituals carried out both at the restructuring of the sanctuary and its monumentalisation are exceptionally well documented. The fills produced a substantial quantity of votive terracottas, pottery, bronze artefacts and numerous Hellenistic and Roman coins, both bronze and silver. The finds, which date the sanctuary’s monumentalisation phase (to date generically attributed to the 2nd century B.C.), are from the beginning of the 2nd century B.C., if not the second half of the 3rd century B.C. Archaeobotanical analyses were undertaken during the course of the excavation. Turkey oak (still present today), beech, maple and silver fir were predominant among the tree species attested at Rossano. Chestnut, walnut and hazelnut trees were also present. As part of the new investigations the Faber srl of Matera was brought in to undertake a three dimensional survey of the entire complex using a laser scanner. This method was chosen for the following reasons: - the possibility of quickly producing precision documentation in all dimensions; - the creation of an exact three dimensional model that constitutes the scientific base necessary for any type of virtual reconstruction of the monument; - the integration of such a model in the reconstruction of the ancient landscape and sanctuary of Mefite whose geology has been heavily disturbed through time.
