Why this?

Maurits Cornelis Escher (1898-1972)
  • Born in Leeuwarden, Netherlands
  • Father was a civil engineer
  • Spent most of youth in Arnhem
  • Failed high school exams.
  • Enrolled in School for Architecture and
    Decorative Arts in Haarlem
  • Within a week decided he wanted to study graphic
    art
  • Moved to Italy
  • met wife
  • lived there for eleven years

4
  • One of his woodcuts he used for the trees in
    Puddle and also in Pintea of Cavi

Other info.
  • Made over 448 lithographs, woodcuts, wood
    engravings
  • Over 2000 sketches and drawings.
  • Left handed

8
More of his Life
  • In 1922, on his visit to Spain, he became
    fascinated with Division Plane
  • Was visiting Alhambra, 14 century Moorish castle.
  • In Switzerland, during WWII, he completed 62 of
    137 Regular Division Drawings

Math?
  • In 1956 he was featured in Time
  • Greatest admires were mathematicians.
  • Visualization of math principles.
  • Had no formal math beyond high school
  • After this adoration, he read more about math,
    dealing with plane and projective geometry.
  • Goes on to use non-Euclidean geometry
  • Love of impossible figures
  • Encompasses geometry of space and logic of space

12
Division Plane
  • Deals with tessellations

13
What is a tessellation?
  • are arrangements of closed shapes that
    completely cover the plane without overlapping
    and without leaving gaps.
  • Usually polygons or similar shapes, like square
    tiles on a floor.

14
His quote on tessellations
  • In mathematical quarters, the regular division
    of the plane has been considered theoretically .
    . . Does this mean that it is an exclusively
    mathematical question? In my opinion, it does
    not. Mathematicians have opened the gate
    leading to an extensive domain, but they have not
    entered this domain themselves. By their very
    nature thay are more interested in the way in
    which the gate is opened than in the garden lying
    behind it.

15
Tessellations Cont.
  • Was thought to just be triangle, squares,
    rectangles, and hexagons
  • Yet, he took his basic problems and applied
    reflections, glide reflections, translations, and
    rotations
  • Also distorted the shapes of animals, birds, and
    others figures.
  • Rule three, four, or six-fold symmetry

16
Polyhedra
  • AMAZING!
  • Platonic solids tetrahedron (4), cube (6),
    octahedron (8), dodecahedron (12), and
    icosahedron (20)
  • What could make these better?
  • Intersect them
  • Stellating (replace each face with a pyramid)

17
Topology
  • Just becoming something of an interest to the
    world in his lifetime.
  • Topology is the mathematical study of the
    properties that are preserved through
    deformations, twisting, and stretchings of
    objects. Tearing, however, is not allowed.
  • Leads to Knots and Knot theory

18
Logic of Space?
  • Spatial relation among physical objects that are
    necessary
  • Optical illusion
  • Use lights and shadows
  • Concave and convex
  • Visual clues
  • Vanishing points
  • Points of infinity by Alberi, and others led to
    projective geometry

19
Self-Reference
  • Escher has many pictures of himself in orbs.
  • The illusion is that the picture seems to draw
    itself or that it will reflect a personal
    reflection.
  • Seems to have intersecting worlds
  • every part of the world seems to contain, and be
    contained in, every other part
  • A reflection of the artist, the artist reflected
    in his work.
