"...it is not surprising that images should move, and agitate their arms and other members, with regularity; for it happens that many an image seems to do this in our sleep. This is to be explained in the following way; that when the first image passes off, and a second is afterward produced in another position, the former then seems to have changed its gesture. This, doubtless, we must conceive to be done by a very rapid process..."The poet Titus Lucretius Carus was speaking of the images of things that form in the mind, but his insight would certainly be a starting point for the technology of cartoon animation, and indeed even of motion pictures and television.
