Convex and Concave 1955

M.C. Escher made "Convex and Concave" using pen and ink, hatching, and cross-hatching. Escher creates the sensation of space through the use of lines and tone; it’s hard to know what’s flat and what’s three dimensional. It looks like he’s built it all up from marks, like a conversation of lines which have layered up to suggest dimension and depth. I wonder if he had to work it all out in his head first or whether the picture emerged and grew through trial, error, and intuition. I feel for him as I see his mind at work, testing possibilities and ideas through the process of drawing. Is it a maze, a building, a puzzle, a game? Escher's world is a theatre of activity and an exchange of ideas. He is an artist in conversation with others, inspiring creativity and showing how we can all embrace uncertainty and ambiguity in our work.
