Carbon dating and the turin shroud

Questi usavano due diverse tecniche di datazione: Nel 1986 Carlos Chagas Filho, presidente della Accademia Pontificia delle Scienze interpella diversi laboratori per lo svolgimento dell'esame al carbonio 14; viene redatto un protocollo comune a sette laboratori (ai sei individuati si era aggiunto il laboratorio di Gif-sur-Yvette (Francia); il cardinale Ballestrero informa i sette laboratori che su suggerimento del consulente scientifico (Luigi Gonnella professore del Politecnico di Torino) solo tre di essi saranno coinvolti nell'analisi.Il criterio di scelta sarà l'esperienza dei laboratori nella datazione dei reperti archeologici Il prelievo dei campioni avvenne il 21 aprile 1988 nella sacrestia del Duomo di Torino da Franco Testore, docente di tecnologia dei tessuti presso il Politecnico di Torino, e Giovanni Riggi di Numana, microanalista.It was moved to the new Savoyard capital of Turin in 1578.Ever since, it has been publicly exhibited only rarely, as, in recent times, on the marriage of Prince Umberto (1931) and on the 400th anniversary of its arrival in Turin (1978).Scholarly analyses—attempting to use scientific methods to prove or disprove its authenticity—have been applied to the shroud since the late 19th century.It was early noticed (1898) that the sepia-tone images on the shroud seem to have the character of photographic negatives rather than positives.What Jesus really looked like may not be as in the portraits of Jesus we see everyday.

Subsequent popes from , and there it was damaged by fire and water in 1532.

Some have noted that the head is 5% too large for its body, the nose is disproportionate, and the arms are too long. In any case, the image is believed by many to be a negative image of the crucified Jesus and the shroud is believed to be his burial shroud. Apparently, the first historical mention of the shroud as the "shroud of Turin" is in the late 16th century when it was brought to the cathedral in that city, though it was allegedly discovered in Turkey during one of the so-called "Holy" Crusades in the so-called "Middle" Ages.

Most skeptics think the image is not a burial shroud, but a painting and a pious hoax. In 1988, the Vatican allowed the shroud to be dated by three independent sources--Oxford University, the University of Arizona, and the Swiss Federal Institute of Technology--and each of them dated the cloth as originating in medieval times, around 1350.

Il primo effettuò le operazioni di pesatura, mentre il secondo eseguì materialmente il taglio.

Presenti tra gli altri all'operazione, oltre ai due scienziati summenzionati, c'erano il cardinale Ballestrero con quattro sacerdoti, Luigi Gonella, il rappresentante dell'Accademia Pontificia delle Scienze, i fotografi e il cineoperatore.
