Some prehistoric cave imagery could appear to move when illuminated by flickering or uneven firelight, although the evidence describes an observed visual effect rather than proving that movement was deliberately intended by the artists.
Some prehistoric cave paintings appear to move when viewed under particular lighting conditions.

Key Evidence
Historic Mysteries describes prehistoric animal images appearing to move as flickering or imperfect light revealed different sections of the paintings in sequence.
The wording is appropriately limited: it refers to an appearance of movement under particular lighting, not literal movement, universal effects, or proven artistic intent.
What the Evidence Shows
The available source supports the core claim. Historic Mysteries reports that imperfect, shifting light in prehistoric caves could reveal different parts of animal images in sequence, making the figures seem to move. That fits the statement’s cautious wording, which says the paintings “appear” to move under particular lighting conditions rather than claiming that they literally move or that every cave painting produces the effect.
The evidence is about perception and illumination, not animation in the modern technical sense. Flickering firelight and changing shadows may have created an impression of motion as viewers saw portions of an image at different moments. The source does not establish how widespread this effect was, whether particular artists intended it, or whether it applied to all prehistoric cave paintings.historicmysteries.comhistoricmysteries.comThe Mystery of Cave Paintings: Early Animation?
On the evidence provided, the statement is supported in its ordinary, limited meaning. Confidence is low because the only claim-bearing source is a secondary website, and no primary archaeological study or independent corroborating source was supplied.historicmysteries.comhistoricmysteries.comThe Mystery of Cave Paintings: Early Animation?
