Photoglyphic engraving from a metal plate. Photograph by William Henry Fox Talbot (1800-1877) who invented the negative/positive process for producing photographs between 1835-1839. The statue, probably made between 160 BC and 20 BC, was unearthed in Rome in 1506. The right arm was missing, and the version of the statue shown here has a 16th-century replacement. The original arm was found in 1957 and re-attached.
