The Volto Santo of Lucca, the 9th century crucifix that is one of the oldest known surviving wooden sculptures in Europe, has been restored to its original polychromy. Overpainted in the 17th century with a black on the robes and brown on the flesh tones then coated with a pigmented wax layer, the figure of Christ and the circular nimbus behind him were dull and dark, obscuring pigments of the highest quality like lapis lazuli blue and gold.
