On the Threshold of Liberty (in French, Au seuil de la liberté) refers to two oil on canvas paintings by the Belgian surrealist René Magritte. The work depicts a large room with the walls paneled with different scenes or windows. Each panel reveals a different subject: a sky, fire, wood, a forest, the front of a building, an ornamental pattern, a female torso and a strange metallic texture featuring spherical bells (a common Magritte element). Inside the room is a cannon.
