Cave of Forgotten Dreams (2010)
While many of Herzog's films focus on particularly iconoclastic personalities, his emphasis sometimes takes the form of meditations on the state of humanity as a whole. Here, his subject is the Chauvet Cave, a site discovered in 1994 that contains a number of prehistoric drawings and paintings. As the camera lingers on the images left behind on the cave's walls, Herzog's narration makes it clear that there's something fundamentally unknowable about them. Are we looking at the product of a handful of people at a particular moment, or at work that accumulated over the course of thousands of years? That we'll never know doesn't make the images before us any less compelling.
