As you may be aware oil painting was for a long time considered to be one of the highest forms of artistic expression. The rich texture and vibrant colors of oil paints provided enormous scope for the artist to express his or her talent. Oil painting continues to be a form of art that is complex and yet exuberant.
Escher constructed a five-sided chamber in which all sides are interchangeable. This is his first print to focus primarily on his idea of relativity, how one object is seen in relation to another. The Islamic figurine of a harpy, a mythical creature with a bird's body and a human head, was a gift from Escher's father-in-law and appears in several of his paintings.
Escher wrote that this print "gives the illusion of a town, of house blocks with the sun shining on them. But again it's a fiction, for my paper remains flat. Escher was famous for his oil paintings, and other fine art gallery reproductions during his school days itself. In a spirit of deriding my vain efforts and trying to break up the paper's flatness, I pretend to give it a blow with my fist at the back, but once again it's no good: the paper remains flat, and I have only created the illusion of an illusion. However, the consequence of my blow is that the balcony in the middle is about four times enlarged in comparison with the bordering objects."
This is one of Escher's earliest prints to explore different levels of reality. The first observed reality is the mirror itself and the objects that surround it. The second is that of the street, which in turn becomes part of the room by its reflection in the mirror.
Escher often used his drawings such as oil paintings, fine art gallery as studies for prints, but he occasionally also experimented with various drawing techniques. His most important experiments are the "scratch drawings" for which he evenly coated the paper with lithographic drawing ink. He then drew on the prepared surface with a pointed tool, scoring or scratching into it to produce his image. This technique, which he first employed in 1929, led Escher directly to his work in lithography.
In May and June 1929 Escher traveled through the mountainous landscape of Abruzzi, Italy, planning to produce an illustrated book on the region. This never materialized, but he did create 28 drawings on oil paintings, fine art reproductions, oil paintings reproductions which he based prints, including this lithograph depicting the town of Castrovalva.
From December 1925 to March 1926 Escher worked on a series of six woodcuts on the theme of the Creation. This one depicts the division of sky and water. A Dutch educational association bought 300 impressions of this oil paintings woodcut to hang in public schools.
Created while Escher was still a student at the School for Architecture and Decorative Arts, Oil paintings reproductions in Haarlem, this is the first print to demonstrate his theory of the regular division of a plane. Escher cut eight heads -- four male and four female -- in the original wood block. The final image was achieved by printing the block four times.
