Summary Author: John Stetson 

The astronomer and artist, Leopold Trouvelot, created a chromolithograph to document the July 29, 1878 total solar eclipse that he observed with a 6.5-inch refractor telescope. The close-up of his chromolithograph shows prominence activity and the Sun's corona. His artistic rendering appears to be remarkable in its similarity to a photograph of another total solar eclipse 139 years later, observed from Fort Laramie, Wyoming on August 21, 2017.

I noticed is that when these two images are viewed together they can appear in 3D (three dimensional) as if you were using a stereoscope. Click here to learn how to see this using cross-eyed viewing techniques.
