A Caravaggio painting discovered after going largely unseen for more than 400 years went on display Thursday in New York ahead of its planned auction in June. The artwork, Judith and Holofernes, depicts a biblical scene by Michelangelo Merisi da Caravaggio, an Italian Baroque master known for his pioneering use of light and darkness.

Painted around 1607, the painting was found in 2014 in the attic of a house near Toulouse, France, by a family investigating a leaky roof. Experts believed it to be untouched since a family member brought it home more than 150 years ago as a souvenir of Napoleon's military campaigns.
