Jeremiah 9:5
"Pellegrino Ernetti (1925–1994) was an Italian Benedictine priest...Father Pellegrino Ernetti allegedly developed the Chronovisor, a device said to capture sights and sounds from the past.
The story credits it with revealing historical speeches, a lost Roman play, and even the crucifixion of Jesus.
An unverified legend, not an established invention or authenticated photograph of the crucifixion.
According to accounts such as those in Father François Brune’s 2002 book Le Nouveau Mystère du Vatican, Ernetti allegedly developed the Chronovisor in the 1950s with a team of 12 scientists, reportedly including Nobel laureate Enrico Fermi and Wernher von Braun.
Despite the intrigue, no working Chronovisor has ever been demonstrated, and no credible technical documentation exists. Investigations have found that some “evidence” cited in the story — such as a 1972 photograph of the crucifixion — was later proven to be a reversed 1931 commercial postcard.
There were at least two notable books about the Chronovisor written in the years after Ernetti's death: a 1997 book in German by Peter
Krassa, Father Ernetti's Chronovisor: The Creation and Disappearance of the World's First Time Machine; and a 2002 book in French, The Vatican's New Mystery by Father François Brune, a French priest who was a friend of Ernetti's. Between themselves, these two volumes collected about all of Ernetti's writings and interviews.
As to the question of where the Chronovisor was, and could we please see it and try it out, Ernetti told Brune that it no longer existed. Fearful of such a powerful technology falling into the wrong hands." ChatGPT
