Can you help us crack the code?

Follow curator Nick, conservator Dana and conservation scientist Lucia on their journey to unravel the mysteries of this fascinating object. Made of a rare plant resin called mopa mopa and decorated with a technique known as Barniz de Pasto, the intricate piece is unlike anything else in our collection.

When it was acquired in 2015, a routine x-ray revealed a remarkable discovery: a vivid skeleton of death, or memento mori, lay hidden beneath a layer of paint, applied some 300 years after it was made.

Watch as the overpaint is finally removed to reveal the skeleton in all his glory, along with a cryptic message – the final part of the puzzle.
