All the illustrations of line drawings of Uxmal in Eduard Seler's monumental study, "Die Ruinen von Uxmal," published in Abhandlungen der Königlich Preussischen Akademie der Wissenschaften. Philosophisch-Historische Klasse, Nr. 3. Berlin: Verlag der Königl. Akademie Kunstwissenschaften, 1917. The more elaborate drawings are signed by Wilhelm von den Steinem and most of the other drawings are consistent with his hand; based on on-site drawings by Seler and other material. I have scanned these images from the copy in the University of Rochester Library, with appreciation. On this web site, the captions are literal translations of the German caption.
