Veil of Veronica
The Saint Veronica Altarpiece is the only painting known to be Ugo's work. It is thought to have been finished between 1524 and 1527, and was originally located in Saint Peter's Basilica in Rome. The painting was placed on an altar directly below the chamber that housed the Veil of Veronica, one of the most important relics in Saint Peter's. The Veil of Veronica is one of the most famous "achierpoita," or Christian relics which bear a likeness of Christ not made by human hand. According to the Bible of Argenteuil, this "acheiropoetos" was produced when Veronica wiped the sweat and blood from Christ's face with a linen cloth and Christ's face left an imprint on this cloth. It is still debated among scholars why Ugo, who was not a well-known or especially talented painter, was chosen to create the altar painting for such a famous relic.
