Purpose of use |
The lithograph is uniquely connected to the article, as (1) the Penrose's discovery of the Penrose stairs was triggered by seeing Escher's earlier work, (2) in turn Escher's creation of Ascending and descending was triggered by seeing the Penrose stairs, and (3) Escher presented the lithograph to Penrose in gratitude. The image both illustrates this remarkable dialogue of mathematics and art, and shows that the lithograph embodies Penrose stairs in its construction. |
