In the course students get acquainted with mathematical structures and principles behind designs. Starting off from existing designs – in a variety of medium and function like architectural ornaments, embroidery, basket weaving, cultic sand and cave drawings – students will analyse their structure and device the mathematical models behind. Topics to be discussed include: transformations and similarity, symmetries, tessellations, fractals, mazes, curves and regular and half-regular solids. After understanding the principle of creating such patterns, they will use them for own, artistic designs, by using traditional techniques (e.g. drawing, printing) or computer tools (like Photoshop, Inkscape) they are familiar with. This course will not provide support for using computers or teach to use special sw tools. Those who are familiar with programming in some appropriate language, may use the computer in a more advanced way to create own works.
Nothing in maths or programming, but curiosity for exploration and interest in analytical thinking. Familiarity with some computer tools for drawing, image processing is handy.
Pair of compasses, straight and triangular ruler, notebook, drawing-sketching gears. Own laptop if you have one.
For making own designs, students need to bring/find materials and equipments they wish to use (e.g. paper, paint, textile, …). Digital works are encouradged, but not a must.

|05.10: Symmetries and friezes|
- The notion of symmetry, symmetry transformations on the plane: translation, rotation, reflection, glide reflection
- Frieze: a one-dimensional repetitive pattern
- Friezes in the history of art – see Hungarian folk art embroidery examples
- Symmetries of friezes – there are only 7 types of friezes, according to the 7 symmetry groups – see the table with names and examples.
- Coloured friezes – see exercise 6.
- The Möbius strip
- Katona, Júlia: Samplebook of Creative Ornamental Art, Typotex Publisher – a great book with a lot of examples of friezes from different cultures, and grids to draw them
- Java applet to explore the structure of the 7 frieze patterns
- Draw a simple form on an A4 sheet, and construct where the following transformations will move it on the plane:
- translation of length 2 cm, in the direction parallel to the shorter side of the paper,
- rotation by 30 degree around the middle point of the paper as rotation center, clockwise;
- reflection on one of the diagonals of the paper
- glide reflection on the other diagonal of the paper, of distance 3 cm
- What is the effect of repeating a symmetry transformation : A translation? A rotation? A glide reflection?
- What is the result of performing two reflections one after the other? Think of the possible relative location of the two mirror lines!
- Draw a simple motive, and using this, sketch different friezes (on ‘sqare paper’).
- Analyze your designs: identify their symmetries, put down the according name. If you have not done all possible types, draw the missing ones.
- Analyze the symmetries of friezes from different cultures – here is the exercise sheet.
- Analyze the coloured friezes : does the colouring change the symmetries, and the size of the unit tile to create the frieze? Here are some examples from Maori designs and some others from the Alhambra, sketched by M. C. Escher.
- It is easy to design a frize for a column or a vase, which are like cylinders. But how to do it for a Möbius strip? Make a Möbius strip from paper and print or draw on it a continous frieze. Experiment with colouring to make your design emphasize the single-sidedness.
Make your work or collected photos electronically available at your own site!
- Make a family of friezes in the medium you like, with at least one example of each of the 7 types. Indicate the type.
- Go out for a hunt for friezes in Budapest. Take photos, and make a collection with note of the exact location, and the type of frieze.
Collect at least one example of all the 7 types. A few tips for good locations: Párizsi udvar, Szervita square – and the staircases of the houses around. The iron fences of the corridors around the internal couryard and stuccos in some of the houses on Nagykörút and Király utca are also interesting. Do not miss the building of the Music Academy on Liszt Ferenc Square, and the building of the Photo Museum nearby.
It is not so easy to get into houses. You could combine your hunt with visits to open ateliers during the Design Week Design Week.
