The Sudarium of Saint Veronica, anonymous, c. 1450
When Christ carried his cross to Calvary, he wiped the sweat from his face with a veil given to him by Veronica. The image of his features became imprinted on the cloth. This miraculous vera icon or ‘true image’ developed into the ‘standard portrait’ of Christ. It was a favourite subject of devotional art in the 15th century.
