Urethanes Technology – A 4th century statue of Emperor Constantine has been recreated for Rome’s Capitoline Museum. The 13m high colossus was reconstructed using materials including polyurethane and marble dust. Only a handful of marble fragments of the original statue remain, most of which are housed in the museum’s courtyard. The full-scale replica was created by the Factum Foundation for Digital Technology in Preservation, under the supervision of the museum’s superintendent of cultural heritage, and with funding from the Prada Foundation.
