The Chronovisor — Vatican's Alleged Time-Viewing Device

In the 1960s, Father Pellegrino Ernetti, an Italian Benedictine monk who was also a physicist and pre-polyphonic music expert at the University of Venice, claimed to have co-built a device called the Chronovisor that could tune into electromagnetic radiation residue left by past events — effectively allowing users to view any moment in history like a television. Ernetti claimed a team of 12 scientists built the device, including (he alleged) Enrico Fermi and Wernher von Braun. He stated he used the Chronovisor to witness the crucifixion of Christ, the destruction of Sodom and Gomorrah, a speech by Cicero, and a performance of the lost play 'Thyestes' by Quintus Ennius in 169 BC — for which he produced a partial transcription. Ernetti produced a photograph allegedly captured through the Chronovisor showing Christ on the cross, though skeptics noted its resemblance to a wooden crucifix in a church in Perugia. Ernetti claimed the Vatican confiscated the device. Before his death in 1994, he reportedly stated that the Chronovisor was real but refused to reveal more. French theologian Father François Brune documented Ernetti's claims in 'Le nouveau mystère du Vatican' (2002). The Vatican has never confirmed or denied the device's existence, but reportedly issued a decree that anyone using such a device would be excommunicated — an odd response to something that supposedly doesn't exist. The Chronovisor connects to the broader pattern of the Vatican possessing or suppressing advanced technology related to the UAP phenomenon, including the 1933 Magenta crash retrieval that Grusch alleges was handed to the Vatican.
