A large range of symmetries in art is presented through clear and aesthetically outstanding examples of historical ornaments. Compendious comments illustrate the selected photographic material by addressing the interested and specialist reader alike.

Contents:
Introduction
Fundamental categories
The convenient start: Plane groups of symmetry
Intertwined patterns: Layer groups of symmetry
Two-colored periodic ornamentation
Polychromatic patterns
Beyond 2D groups: Hypersymmetry, superstructures, two symmetries in one pattern, the...

This is the first book to provide a comprehensive treatment of theories and applications in the rapidly expanding field of the crystallography of molecular materials. Molecules are the natural modules from which molecular crystalline structures are built. Most inorganic structures, however are infinite arrays of atoms and some kinds of surrogate modules, e.g. coordination polyhedra, are usually used to describe them. In recent years, the attention has been focused on complex modules as the basis for a systematic description of polytypes and homologous/polysomatic series (modular structures)....
