When an old painting shows signs of decay, most people’s instinct would be to restore it, so as to bring it closer to how it originally looked like. However, some paintings – especially illuminated manuscripts – are too delicate to physically be restored. Surprisingly, mathematics may be able to help in this case: as a new article published in Heritage Science shows, mathematics can be used to not only digitally restore a painting, but also re-establish original versions of overpainted paintings, and even animate artworks.
The Ruby Slippers, worn by Judy Garland in the 1939 movie The Wizard of OZ, are an iconic piece of cinematic history and popular culture.

But what are Dorothy’s slippers made of? A detailed material analysis published in Heritage Science tries to answer this question.
