I want to talk about litography and a Litography artist I admireLithography is a printing process developed in 1796 in Germany. In the lithographic technique the different adhesion between hydrophilic and hydrophobic substances are used. Rejects water as greasy inks, oily areas not printed but are at the same level. With these inks, the drawing to be reproduced is mapped, which is fixed using a solution of  acid nitric  and  arabic gum . For this type of printing  polished limestone on which the image to be printed inverted with a fat, is drawn with a brush or pencil.

Escher, was a Dutch artist known for his woodblock and lithographic prints dealing with impossible figures, tessellations and imaginary worlds.

Along his career made ​​over 400 lithographs and woodcuts, and some 2,000 drawings and drafts.

Not based his work on feelings, like other artists, but simply in situations one of its main features is the duality and the search for balance, the use of white and black, symmetry, infinity against the limited, which represented every object has its counterpart.

His imaginary could be divided into three : Space structure, surface structure, and the projection of the three-dimensional space in the plane.

I elected Escher because I think his imagination and lithographic technique are a unique invoice. Impossible figures, metamorphosis and game structure, and surface reality.
His work experience  with different methods of representing paradoxical spaces that defy the usual modes of representation.
