Images from a book published in 1888 — Untersuchungen über Dämmerungserscheinungen: zur Erklärung der nach dem Krakatau-Ausbruch beobachteten atmosphärisch-optischen Störung, which roughly translates as “Studies on twilight phenomena: to explain the atmospheric-optical disturbance observed after the Krakatau eruption.” While most of the book is an exploration via text, by the German physicist Johann Kiessling, the final pages are given over to a wonderful series of chromolithographs from watercolour images by Eduard Pechuël-Loesche, a few of which are selected here.
