The symmetrical design called dyrnak gul is characterized by diagonal lines and angular projections. Its symmetry of form relies upon reflection along two axes. Color alternation plays with this symmetry, drawing attention to the inherent rotation.
Two slightly different forms of dyrnak gul are repeated to form the field pattern, which is based upon reflection and glide reflection. Combining these two symmetry operations also results in rotation. Can you locate the centers of rotation?
In most Oriental rugs, a main border surrounds the central field. Typically, there is an awkward transition from the sides to the top and bottom borders, as you can see in this rug. Here, the border pattern utilizes reflection and glide reflection.
