Il disegno dell’apparechio aquilano nell’architettura religiosa dal XII al XIV secolo

Ignazio Carlo Gavini (1931), obseres - in some buildings of the city of L'Aquila and of the surrounding tertitory - the use of a particular constructive technique for the realization of stone masonries, calling it the "apparecchio aquilano" (Masonry System of L'Aquila). This technique is characterized by a face realized in little stony ashlars, placed in staggered horizontal courses. The apparecchio quilano morphologically recalls the Roman opus reticulatum and the opus vittatum, and its reintroduction might be due to the Benedictine culture. The presence of some ashlars in a vertical position, recalls an influence of some constructive manners typical of the Cistercian architecture , that are visible as well on the edge disposition of some elements or like in the opus spicatum. A wide research has consented to verify that the apparecchio aquilano is diffused in all the southern slope of the Gran Sasso massif, even with different, in part, from the examples of the chief town, in dimensions and in workmanship of the stony elements. The classification of the constructive techniques of the proposed masonries allows to correlate the analysed masonries with their historical-territorial context, and to compare the various constructive types with the documented data. In the light of the available data, the typologies in regular ashlars are present from the XIIth Century to the XVth Century; while the examples with little ashlars from the XIth Century to the XV Century.
