There are many relics attributed to Jesus that people believe or believed to be authentic relics of the Gospel accounts.
The Shroud of Turin is perhaps the best-known relic; its authenticity was questioned due to radiocarbon dating, performed in 1988, the accuracy of which has itself been subsequently questioned. The earlier-measured sample was generally agreed to have been thrown off by contamination on the shroud, though retests are also debated, and it remains a controversial item.
Another famous relic is the Holy Chalice which Jesus used at the Last Supper. Stories of this relic are often intertwined with medieval legends around the Holy Grail.
Pieces of the True Cross, including the half of the INRI inscription tablet, preserved at the ancient basilicaSanta Croce in Gerusalemme in Rome. Very small pieces or particles of the True Cross are preserved in hundreds of other churches in Europe and inside crucifixes. According to Gerasimos SmyrnakisRohault de Flery calculated that the total volume of the True Cross was 178,000,000 cubic millimeters but by his time only 3,942,000 cubic millimeters survived. Smyrniotakis noted the largest part (870,760 cubic millimeters) was in Mount Athos, 537,587 in Rome, 516,090 in Brussels, 445,582 in Venice, 436,450 in Ghent and 237,731 in Paris.
In 2002, the James Ossuary was found. This ossuary which bears the inscription Ya`aqov bar Yosef akhui Yeshua` ("James son of Joseph brother of Jesus") came to light under questionable provenance and was thought by some to be historical evidence for Jesus's brother James. On June 18, 2003, the Israeli Antiquities Authority published a report concluding that the inscription on the ossuary is a modern forgery based on their analysis of the patina. It appears that the inscription was added recently and made to look old by addition of a chalksolution. The dealer, Oded Golan, was arrested at his Tel Aviv home July 21, on suspicion of forging ancient artifacts. He was released on July 25; as of August 8 charges had not yet been filed against him. Allegedly, authorities found forgery equipment and partially completed forgeries in Oded Golan's home.
In the work Asarim, by Marisa Vallejo, a bloodstained cloth called the Sudarium (John 20:7) is described as a turban or napkin (Gk. σουδάριον) wound around Jesus' head at the time of his burial. It is claimed that this is the cloth that was set aside in the tomb after the Resurrection. This relic can be seen in the Cathedral of Oviedo in Spain. There is some evidence that at some stage in time, this cloth and the Turin Shroud covered the same dead body.
