Secondo Pia

The famed photograph

On 25 May 1898, after the opening ceremony and during the noon closure of the exhibition, Pia set up equipment in Turin Cathedral. Two other people, Father Sanno Salaro and the head of cathedral security, Lieutenant Felice Fino, were also present and took part in the photography. It was one of the first times an electric light bulb was used to take a photograph.

The logistics of organizing the photographic session and the required equipment were a challenge to Pia, but he managed to set up two electric lamps of about 1000 candelas each. Since there was no electricity in the cathedral, Pia set up a portable generator. He managed to make a few exposures in the resulting heat before the session was interrupted by the opening of the cathedral doors after the noon closure. The results of this session were not successful once the plates were developed.

Three days later, on the evening of 28 May, Pia returned for a second session at about 9:30 pm and took a few more exposures. Based on his experience of 25 May, he varied the exposure times and the lighting. At around midnight the three men went back to develop the plates. Pia later said that he almost dropped and broke the photographic plate in the darkroom from the shock of what appeared on it: the reverse plate showed the positive image of a man and a face in a detail that could not be seen with the naked eye.

Ongoing developments

On 2 June 1898, the exhibition ended and the shroud was returned to its casket in the royal chapel. Genoa's Il Cittadino newspaper reported Pia's photograph on 13 June, and a day later the story appeared in the national newspaper Corriere Nazionale. On 15 June the Vatican newspaper Osservatore Romano covered the story.

The next few years witnessed a number of debates about Pia's photograph, with various suggestions of supernatural origin versus accusations of errors in his work, his doctoring of the photographs, etc. In the meantime, King Umberto I of Italy, whose permission was instrumental for the Pia photograph, was assassinated in July 1900 and did not see the full story unfold.

Some definite support for Secondo Pia eventually arrived in 1931 when a professional photographer, Giuseppe Enrie, also photographed the shroud and his findings supported Pia. When Enrie's photograph was first exhibited, Secondo Pia, then in his seventies, was among those present for viewing. Pia reportedly breathed a deep sigh of relief when he saw Enrie's photograph.

The scientific and religious discussions and debates about the origins of the image that Pia photographed continued. On the religious front, in 1939 Pia's negative image was used by Sister Maria Pierina De Micheli, a nun in Milan, to coin the Holy Face medal, as part of the Catholic devotion to the Holy Face of Jesus. Pope Pius XII approved the devotion and the medal and in 1958 declared the Feast of the Holy Face of Jesus as Shrove Tuesday (the Tuesday before Ash Wednesday) for all Roman Catholics. On the occasion of the 100th year of Secondo Pia's first photograph, on 24 May 1998, Pope John Paul II visited Turin Cathedral. In his address on that day, he said, "the Shroud is an image of God's love as well as of human sin", and he called the shroud "an icon of the suffering of the innocent in every age".

On the scientific front, in 2004 the optical journal of the Institute of Physics in London published a reviewed article on new imaging techniques applied to the shroud during its restoration in 2002. Scientific debate about the image and the shroud continues with international conferences.
