Documentazione e restauro virtuale degli antichi colori dell'ara della Vestale

Abstract

La ricerca si è proposta di documentare e ricostruire digitalmente l’ara della Vestale Cossinia di Tivoli, per restituirne l’aspetto originario, ipotizzando anche la presenza di colori. Il modello digitale reality-based è frutto di diverse campagne di rilevamento effettuate con strumentazione laser scanner e con fotogrammetria digitale. Con questa in particolare è stato possibile ricostruire digitalmente l’ara non solo nelle sue caratteristiche morfologiche, ma anche nel dettaglio superficiale, ponendo grande attenzione nel riportare il colore attuale. Il modello digitale è servito per operare un restauro virtuale che ha permesso di rimuovere digitalmente le scritte vandaliche; successivamente, sul modello sono stati riproiettati i colori che si ipotizza possano aver caratterizzato l’aspetto originario dell’ara. La presenza del colore è stata ipotizzata per analogia con altri manufatti, sulla base dei risultati degli studi sulla policromia sia nell’architettura che nella statuaria greca e romana; la scelta dei singoli colori è stata basata anche sulle notizie ricavabili dalle fonti storiche e dalle conoscenze fornite dalla ricerca archeologica.

Cossinia: 3D model and virtual restoration of colour This research proposes a hypothesis on the original colours of the ara, referring to specific studies and data derived from other archaeological finds. The rendering image has been created using a reality-based digital model, obtained from several survey campaigns, carried out with laser scanning and digital photogrammetry technologies.
