The Italian Ministry of Culture has confirmed the restoration of a pair of bronze testicles to a second-century Roman mosaic depicting the god Mithras slaying a bull. The appendages, long regarded by locals as a fertility charm, were removed in 2017 during a conservation project that deemed them a later addition. The decision to reinstate them follows a campaign by residents of the Lombardy town where the mosaic is housed.
British archaeologists have expressed cautious approval. Dr. Eleanor Hartley of the British School at Rome described the restoration as “a pragmatic recognition of the site’s living cultural significance.” She added that while the testicles are almost certainly a medieval or Renaissance addition, they have acquired their own heritage value over centuries.
The mosaic, discovered in the 1980s, shows Mithras in the act of tauroctony. The bull’s genitalia had been cast in bronze and attached to the stone, a feature that drew tourists and local devotees. During a 2017 cleaning, conservators removed the testicles, citing corrosion and the need to preserve the original Roman surface. Protests followed, with some residents claiming the removal had brought bad luck to the region.
Professor Michael Thorpe, a specialist in Roman archaeology at Oxford, noted that the case highlights tensions between academic conservation ethics and public engagement. “The mosaic is not a static artefact. Its meaning has evolved. To ignore that is to treat heritage as a museum specimen rather than a living part of a community,” he said.
The Italian ministry stated that the testicles have been reattached using reversible methods and that a plaque will explain their contested history. The restoration has been welcomed by local tourism officials, who expect a surge in visitors.
Critics, however, argue that the decision sets a precedent for altering ancient works to suit modern sensibilities. Dr. Sofia Bianchi of the University of Milan called it “a capitulation to superstition.” She warned that other sites might face pressure to restore apocryphal features.
Despite the controversy, the mosaic now displays its full bronze genitalia once more. For many in the town, the bull’s luck has returned.
