athematical objects have often been an object of artistic depiction. Of all the painters
dealing with mathematical themes, probably the most famous was the Dutch graphic artist
Maurits Cornelis Escher. In his drawings, he dealt inter alia with the perception of infinity,
tessellations, rendering impossible objects and drawing topologically (math) interesting motifs.
Among the latter,

*Knots*
are particularly famous.

Some of his drawings are based on the concept of the so-called Penrose Triangle;

*(see the top of this page).*
It represents an impossible object, created in the 1950s by Lionel Penrose and his son Roger Penrose.

**Möbius Strip**

Unlike an ordinary strip, which has two sides and two edges, the
Möbius strip has only one side and only one edge. Such a surface was discovered by the German mathematician
August Ferdinand Möbius. Möbius strips have entered our culture in
many ways. It appears as an object of art, as in Escher's
woodcut

*Möbius Strip II.*
