A concise introduction to the principles and practice of eurythmy, the new art of movement initiated by Rudolf Steiner. This useful guide includes brief survey of dance -- from its origin in the ancient mysteries to its contemporary forms -- which places Steiner's ideas in their historical context. His insight into the hidden laws of movement -- a realm of forces designated by Steiner as the etheric -- is also explained. Eurythmy is shown to be speech and music made visible.
