Trouvelot made some fifteen thousand drawings at the eyepiece, and in 1882 Charles Scribner's Sons published fifteen of them as chromolithographs at a scale nobody has attempted since. Photography could already record where things were; it could not yet record how they looked. So for one narrow decade the most accurate images of the sky were made by a man drawing what he saw, in pastel, by lamplight — and they remain the most beautiful. Trouvelot is otherwise remembered for accidentally releasing the gypsy moth into North America, which is a hard thing to have on the same résumé.
