Commentary In the foreground, don Quixote mounted on Rocinante (its legs tied) and Sancho relieving himself; notice don Quixote's gesture covering his nose.
In the background, don Quixote and Sancho discover the fulling mills; after that, it begins to rain.
Drawing and engraving done to look archaic. 
Notes 1 – Copied after the illustration for Barcelona: Juan Jolis, 1755 (and 1762), copied after Madrid: Antonio Sanz, 1735, badly copied after Diego de Obregón’s illustration (Madrid: Andrés García de la Iglesia, 1674).
2 - In Obregón's illustration, don Quixote was not mounted on Rocinante (less accurate to Cervantes' text).
