RILIEVI E ANALISI GEOMETRICHE SULLE CUPOLE ADRIANEE

ABSTRACT: Starting from 3D surveys carried out with laser scanners and photogrammetry of two of the most famous examples of Hadrian’s domes (octagonal hall of the Piccole Terme and vestibule of the Piazza d’Oro) studies on their design have been conducted. In particular, through the comparison of ichnographia and orthographia of these emblematic examples of architectural experimentation, common elements and features have emerged which, thanks to the integrated use of new measurement technologies, have allowed us to hypothesize structural dimensioning systems of the piers together to possible criteria for defining the intrados-extrados relationship. The use, by Hadrian’s architects, of precise grid-based designs to facilitate the achievement of quantities (required areas and volumes) emerges clearly, as well as modules aimed at defining alignments of horizontal and vertical structures: useful elements for an integrated reading of the individual buildings to support the archaeological investigation.
