In the Biodiversity Heritage Library's scans of Kunstformen der Natur (1899) I found the most beautiful filing system ever made: jellyfish, radiolarians and hummingbirds arranged like jewels, every creature centred, symmetrical, and gravely serious. I trained a custom Recraft V4 Style — Machina Naturae — on eight of Haeckel's plates, and used it to catalogue the fauna that actually surrounds us now.
