St. Veronica is believed to be the pious matron of Jerusalem who, moved with pity as Jesus carried the cross to Calvary, wiped His face with her handkerchief or cloth was left with the clear and miraculous imprint of Jesus' face. In western tradition, Veronica was called to Rome by the Emperor Tiberius who was cured of his illness when she touched him with the cloth, which at her death she left to Pope Clement.
The story of Veronica found in the apocryphal Acts of Pilate identifies her as the woman mentioned in the Gospel of Matthew whom Jesus healed of a blood issue. In France, she was known as the wife of Bacchus, who helped to evangelize the south of France when her husband became a hermit.

The veil was seen in Rome in the 8th century and by the request of Pope Boniface VIII placed in St. Peter's in 1297. In popular speech of the time, the veil was referred to as the Veronica, a name made up of the Latin word 'vera' and the Greek word 'icon', together meaning "true image".

It was mentioned in several medieval texts by the Bollandists, and Matthew of Westminster speaks of an image of Jesus called Veronica.

Thus, it is said that the name which referred to the cloth was mistaken for the name of a person. Although St. Veronica's name is not mentioned in Scripture and she is not included in Roman Martyrology, the memory of her single act of charity is commemorated in the 6th Station of the Cross and she is given a feast day. Veronica's veil, bearing the face of Christ and the Crown of Thorns is one of the most cherished relics of the Church.
