Science Art: Partial Eclipse of the Moon by Étienne Léopold Trouvelot

Almost a crescent. A moon of the late 1800s.

An astronomical drawing from the French-born Harvard researcher who, as an entomologist (as well as an astronomer), unleashed the horribly invasive gypsy moth on North America’s unsuspecting forests. He was trying to make silk. Oops.
