Commentary "... that some should reach his nose, and soon as they did he came to its relief...".
Don Quixote discovers that Sancho has relieved himself (notice his gesture covering his nose).
The scene has been resolved without excessive crude humour; Sancho appears behind Rocinante.
Jiménez Aranda's drawing skill is masterly; the illustration, almost in complete darkness, is worth noting. 
Notes 1 – Reproduction of the original sketch (Chinese ink and gouache white). Jiménez Aranda meant to paint a more-finished drawing after this sketch using natural sceneries and real models, but he died before completing the project.
