I remember seeing a series of Victorian-era illustrations about what they thought the future might look like. There was a picture of children with early diving suits playing croquet underwater, a whale with an ornate trolley attached, and a flying battleship held up by a balloon, among others. In the 50s there came Raypunk art, full of visualizations of atomic energy being used in every day life. My question is, is there any evidence our ancient predecessors did the same?
