Who attempted to show motion by placing images side by side?

• A. Michelangelo
• B. Cave Paintings
• C. Thaumatrope
• D. Magic Lantern

Answer: (A)

The concept here is how early devices conveyed motion by presenting images in a way the eye fuses into movement. A thaumatrope does exactly that: it’s a disk with two different images on opposite sides, connected by a string. When you spin it quickly, the images alternate so fast that your brain merges them, creating the impression of a single combined image or a simple motion illusion. This uses the brain’s persistence of vision to produce motion from side-by-side, rapidly changing visuals. The other options don’t fit this mechanism: cave paintings are static depictions with no rapid sequence; the magic lantern projects slides to tell stories but its motion comes from changing slides, not from two images on one surface being viewed together; Michelangelo is a painter/sculptor known for static works rather than devices designed to show motion. So the thaumatrope is the best fit for showing motion through paired images on a rotating medium.
