Abstract
As is well known, the possible paths of Roman road tracks often have as their confirmation the land and sea routes re- ported on the Itinerarium Provinciarum Antonini Augusti (Parthey and Pinder, 1848) and those reported of the Tabula Peutingeriana (Miller, 1964). A recent monograph on the archae- ological area of the city of Morgantina (Bruno, 2017), addresses the theme of the extra-urban viability of the city which, ac- cordingtothereconstructions,likelyhas been located near the route of the Itin- erarium Provinciarum Antonini Augusti n. 88 Catania-Agrigento, at least until the beginning of the fourth century d.C. In the monograph the author, based on topographic data and historical sources, reconstructs the road layout and the pos- sible locations of mansiones and/or muta- tiones along it. In particular, accrediting a possible key to reading of the It. Ant. Aug. n. 88 advanced by another researcher (Bonacini, 2010), he hypothesizes the ex- istence of a Mutatio Gelasium and places it inside the Chora di Morgantina. Inordertoascertaintheexistenceand exact location of the Mutatio Gelasium, along the aforementioned road layout, surveys and sampling of earthenware for mineralogical-petrographic analyses in the laboratory were performed. The first phase the survey consisted of a geomorphological study, aimed at defining the plano-altimetric character- istics of the Roman road section between the Mansiones Capitonianis and the Mu- tatio Gelasium and of the litotypes out-cropping along the same path. In the second phase, the reliefs were concen- trated in the area around the Masseria Belmontino Sottano, in the homony- mous district, and consisted of an aero- fotogrammetric survey conducted with drone and in the sampling of terracotta samples on which petrographic analyses were conducted on thin section, through a polarized light transmitted microscope, and X-ray diffractometry. The results obtained, although pre- liminary,areveryencouragingandindi- cate the presence, in the area around the farm, of numerous traces of perimeter and/or foundation walls of buildings made up of several square-shaped com- partments placed side by side. The analyses carried out on the finds of earthenware indicate that all the sam- ples analysed show petrographic charac- teristics common to those of Greco-Ro- man terracotta in central-eastern Sicily (Barone et al., 2005; Barone et al., 2012; Barone et al., 2014). The X-ray diffrac- tometric analyses have shown the pres- ence of quartz, hematite and k-feldspar also of new Ca-silicatic phases (anor- thite, diopside and sporadic gehlenite) which indicate cooking temperatures close to 850° C.
