Course Information


Math and the Art of M.C. Escher
MWF 9:00 am - 9:50 am
Ritter Hall 316

Prerequisite: 3 years of high school mathematics or MT A 120 (College Algebra).

Course Goals

  1. Develop an intuitive understanding of geometry by looking at examples and applications in art (mainly Escher’s work, but also some other modern artists).
  2. Develop a thorough understanding of the concepts and techniques of geometry.
  3. Further develop the ability to apply your knowledge of geometry to solve unfamiliar problems.
  4. (Further) develop skills for working effectively with others on mathematics problems.

Math and the Art of M.C. Escher is an inquiry based course. Inquiry based courses depend on a process called Cooperative Learning. Some helpful facts are described on this page that will help you succeed andexcel in this course.

  • The online textbook Math and the Art of MC Escher, at
  • M.C. Escher: Visions of Symmetry by D. Schattschneider. W.H. Freeman and Company (1990)
  • Flatland: A romance of many dimensions by E.A. Abbott, Dover Publ. (1992). Note that Flatland can also be found in its entirety on the internet. You may of course buy a hard copy if you prefer a book.


  • Two exams – 15% each
  • Tessellation Project – 10%
  • Basilica Cathedral Fieldtrip - 10%
  • Saint Louis Museum Fieldtrip - 5%
  • Homework, in-class work, attendance – 20%
  • Final – 25%

Grades:93-100 A, 89-92 A-, 86-88 B+, 82-85 B, 80-81 B- 77-79 C+, 70-76 C, 60-69 D, 0-59 F

Curve: I do not technically grade on a curve, but your work will of course be compared to that of your classmates, and even to students who have taken the class before you. To give an example: when evaluating answers that require an explanation, I will collect all the answers I consider “A-level” and then rank them. If the question is worth 20 points, an A is somewhere between 18 and 20 points. The best answers will receive 20 points, the next best group will receive 19 points, and the others 18. They are all awarded an A, but the best answers receive a few more points. If someone writes answers that are truly excellent, then I will award extra credit.

How to do well: Attendance and participation is extremely important. Missing class regularly causes students quite a bit of trouble. It is very hard to make up this material on ones own.


Week 1 (Aug 25 - Aug 29) Symmetry and Rozette Patterns

Introduction to the course; First topic is "Symmetry"
Wednesday we do the Symmetry of Stars and Polygons Exploration and Rozette Symmetry Groups with Kali Exploration.

On Friday: Rotational and Reflectional Symmetry in Escher’s Sketches

On Friday Homework #1 is due: Read Visions of Symmetry pg. 1-15.
Read M.C. Escher and Introduction_to_Symmetry.
Do Rosette Exercises # 1-5, 8-12, 14

Week 2 (Sep 1 - Sep 5) Symmetry, Isometries, and Frieze Patterns

Monday September 1 is Labor Day: Official University Holiday

Start on Frieze patterns - also known as Borderpatterns. Use examples from earlier work to define reflections and translations. Discuss the difference between a symmetry and an isometry. Define translations and glide-reflections.

  • Do Frieze Names Exploration (Wednesday)
  • On Friday we discussed homework. Some important points to remember:
    • The homework prepares you for the exams. You need to solve all the problems assigned.
    • Starting early so that you can ask for help is very important.
    • Write up nice detailed solutions. Complete sentences should be the rule. Remember that you will be referring to your work when you study for exams. Write down enough so that your answers will be clear to you several weeks from now.
