Diptych with Scenes from the Passion of Jesus – French – The Metropolitan Museum of Art https://www.metmuseum.org/art/collection/search/464288
This diptych, or pair of folding panels, is formed of two slabs of ivory connected with metal hinges, allowing them to fold together to protect the carvings on the interior. It was once possible to lock the panels by means of a now missing sliding hook that locked into the iron mount on the top of the right panel
