Del discrimine tra scienza e tecnica.Il rilievo dei mosaici dell'Accademia di Scherma al Foro Italico

The device discovery, graphical depiction and analysis conducted in the Oval Room of the Academy of Fencing at the Foro Italico in Rome, designed by Luigi Moretti as the input of honor for the athletes, are concentrated in the inner two mosaics, floor of the Oval Office polychrome and the Flight of Icarus located on the north elevation of the former library, Angelo Canevari. The results arising deepen, as well as geometric aspects of the room (oval or elliptical?) And state of preservation, although some particular aspects such as, for example, rethinking the design of the mosaic floor, as in some designs of the project 's archive, which contains two foil fencers, however, are not present in the photograph of the magazine Architecture in 1937. The process of construction of the shape of the room, as emerged from the survey, in comparison of the geometrical method and direct trilaterazioni, detects an absolute contiguity between formal oval and ellipse. The deviations between the two curves can be considered substantially negligible, if only for the fact that the size of the room so modest bear without any difficulty both the processes of construction planimetric.

Le operazioni di rilevamento, restituzione grafica ed analisi condotte nella Sala Ovale dell'Accademia di Scherma al Foro Italico di Roma, pensata da Luigi Moretti come ingresso d'onore per gli atleti, vengono concentrate su due mosaici quello interno, pavimentale, della Sala Ovale e quello policromo del Volo di Icaro ubicato sul prospetto nord della ex biblioteca, di Angelo Canevari. I risultati scaturiti approfondiscono, oltre agli aspetti geometrici della Sala (di forma ovale o ellittica?) ed allo stato di conservazione, anche alcuni aspetti particolari quali, per esempio, i ripensamenti progettuali del mosaico pavimentale, visto che in alcuni disegni di progetto d'archivio, figurano due schermidori di fioretto che, invece, non sono presenti nella fotografia della rivista Architettura del 1937. Il percorso di costruzione della forma della sala, così come scaturita dal rilievo, nel confronto tra metodo geometrico e trilaterazioni dirette, registra una situazione di assoluta contiguità formale tra ovale ed ellisse. Gli scostamenti tra le due curve possono considerarsi sostanzialmente trascurabili, non fosse altro, per il fatto che le dimensioni così modeste della sala sopportano senza difficoltà alcuna entrambe i processi di costruzione planimetrica.
