The Veil of Veronica, or Sudarium (Latin for sweat-cloth), also known as the Vernicle and often called simply the Veronica, is a Christian relic consisting of a piece of cloth said to bear an image of the Holy Face of Jesus produced by other than human means (an acheiropoieton, "made without hand"). Various existing images have been claimed to be the original relic, as well as early copies of it; representations of it are also known as vernicles.

The story of the image's origin is related to the sixth Station of the Cross, wherein Saint Veronica, encountering Jesus along the Via Dolorosa to Calvary, wipes the blood and sweat from his face with her veil. According to some versions, St. Veronica later traveled to Rome to present the cloth to the Roman Emperor Tiberius. The veil has been said to quench thirst, cure blindness, and even raise the dead.

The first written evidence of the story is from the Middle Ages, and during the 14th century, the veil became a central icon in the Western Church. In the words of art historian Neil Macgregor, "From [the 14th Century] on, wherever the Roman Church went, the Veronica would go with it." The act of Saint Veronica wiping the face of Jesus with her veil is celebrated in the sixth Station of the Cross in many Anglican, Catholic, and Western Orthodox churches.

The Manoppello Image is a piece of linen cloth depicting the face of Jesus Christ (17.5 cm wide and 24 cm high) that is stored in a church in the village of Manoppello, Italy. The church, known as Santuario del Volto Santo, is part of a monastery belonging to Capuchin friars. There have been claims that the cloth is the Veil of Veronica.

According to local tradition, an anonymous pilgrim arrived in Manopello in 1508 with the cloth wrapped in a package. The pilgrim gave the package to Dr. Giacomo Antonio Leonelli, who was sitting on a bench in front of the church. The doctor went into the church and unwrapped the package, discovering the veil. He immediately left the church to find the pilgrim but could not trace him. The veil was owned by the Leonelli family for a century. In 1608, Pancrazio Petrucci, a soldier married to Marzia, a member of the Leonelli family, stole the veil from his father-in-law's house. A few years later, Marzia sold it for 400 scudi to Doctor Donato Antonio De Fabritiis to pay a ransom demand for her husband who was a prisoner in Chieti. The veil was given by De Fabritiis to the Capuchins who currently hold it today. This history has been documented by Father Donato da Bomba in his Relatione historica and is based on research that had been started in 1640.

According to Christian tradition, the Image of Edessa was a holy relic consisting of a square or rectangle of cloth upon which a miraculous image of the face of Jesus Christ had been imprinted—the first icon (lit. 'image'). The image is also known as the Mandylion (Greek: μανδύλιον, 'cloth' or 'towel'), in Eastern Orthodoxy, it is also known as Acheiropoieton (Greek: Εἰκόν' ἀχειροποίητη, lit. 'icon not made by hand').

In the tradition recorded in the early 4th century by Eusebius of Caesarea, King Abgar of Edessa wrote to Jesus, asking him to come cure him of an illness. Abgar received a reply letter from Jesus, declining the invitation, but promising a future visit by one of his disciples. One of the seventy disciples, Thaddeus of Edessa, is said to have come to Edessa, bearing the words of Jesus, by the virtues of which the king was miraculously healed. Eusebius said that he had transcribed and translated the actual letter in the Syriac chancery documents of the king of Edessa, but who makes no mention of an image.[3] The report of an image, which accrued to the legendarium of Abgar, first appears in the Syriac work, the Doctrine of Addai: according to it, the messenger, here called Ananias, was also a painter, and he painted the portrait, which was brought back to Edessa and conserved in the royal palace.

The first record of the existence of a physical image in the ancient city of Edessa (now Urfa) was by Evagrius Scholasticus, writing about 593, who reports a portrait of Christ of divine origin (θεότευκτος), which effected the miraculous aid in the defence of Edessa against the Persians in 544. The image was moved to Constantinople in the 10th century. The cloth disappeared when Constantinople was sacked in 1204 during the Fourth Crusade, and is believed by some to have reappeared as a relic in King Louis IX of France's Sainte-Chapelle in Paris. This relic disappeared in the French Revolution.

The provenance of the Edessa letter between the 1st century and its location in his own time are not reported by Eusebius. The materials, according to the scholar Robert Eisenman, "are very widespread in the Syriac sources with so many multiple developments and divergences that it is hard to believe they could all be based on Eusebius' poor efforts".

The Eastern Orthodox Church observes a feast for this icon on August 16, which commemorates its translation from Edessa to Constantinople.

The Sudarium of Oviedo, or Shroud of Oviedo, is a bloodstained piece of cloth measuring c. 84 x 53 cm (33 x 21 inches) kept in the Cámara Santa of the Cathedral of San Salvador, Oviedo, Spain. The Sudarium (Latin for sweat cloth) is thought to be the cloth that was wrapped around the head of Jesus Christ after he died as described in John 20:6–7.

The cloth has been dated to around 700 AD by radiocarbon dating. However, at the same conference at which this information was presented, it was noted that in actuality the cloth has a definite history extending back to approximately 570 AD. The laboratory noted that later oil contamination could have resulted in the late dating.

The small chapel housing it was built specifically for the cloth by King Alfonso II of Asturias in AD 840; the Arca Santa is an elaborate reliquary chest with a Romanesque metal frontal for the storage of the Sudarium and other relics. The Sudarium is displayed to the public three times a year: Good Friday, the Feast of the Triumph of the Cross on 14 September, and its octave on 21 September.

The Sudarium shows signs of advanced deterioration, with dark flecks that are symmetrically arranged but form no image, unlike the markings on the Shroud of Turin. The face cloth is mentioned as having been present in the empty tomb in John 20:6–7. Outside of the Bible the Sudarium is first mentioned in 570 AD by Antoninus of Piacenza, who writes that the Sudarium was being cared for in the vicinity of Jerusalem in a cave near the monastery of Saint Mark.

The Sudarium is presumed to have been taken from Palestine in 614 AD, after the invasion of the Byzantine provinces by the Sassanid Persian King Khosrau II. In order to avoid destruction in the invasion, it was taken away first to Alexandria by the presbyter Philip, then carried through northern Africa when Khosrau II conquered Alexandria in 616 AD and arrived in Spain shortly thereafter. The Sudarium entered Spain at Cartagena, along with people who were fleeing from the Persians. Fulgentius, bishop of Ecija, welcomed the refugees and the relics, and gave the chest containing the Sudarium to Leandro, bishop of Seville. He took it to Seville, where it spent some years.

In 657 it was moved to Toledo, then in 718 on to northern Spain to escape the advancing Moors. The Sudarium was hidden in the mountains of Asturias in a cave known as Montesacro until king Alfonso II, having battled back the Moors, built a chapel in Oviedo to house it in 840.
