On June 21, 1838, Charles Wheatstone, the inventor of 3D anaglyphs, read his treatise, "On Some Remarkable, and Hitherto Unobserved, Phenomena of Binocular Vision," to the Royal Society of London. The article was accompanied by 11 simple line drawings, to demonstrate the new science of "stereoscopy." They were the first 3D anaglyphs ever published.

I have precisely redrawn Wheatstone's original 11 stereoscope figures -- labeled "Fig. 10" through "Fig. 20" just as in the original source -- showing them as red/cyan anaglyphs. Figures 10 through 16 also have Wheatstone's descriptions (he didn't describe figures 17 through 20).

With one exception (Fig. 20), the drawings are minimally simple, no more than doodles of circles, lines and squares. Wheatstone deliberately avoiding shading or color, "...for had either shading or colouring been introduced it might be supposed that the effect was wholly or in part due to these circumstances, whereas by leaving them out of consideration no room is left to doubt that the entire effect of relief is owing to the simultaneous perception of the two monocular projections, one on each retina."
