Enhancing the dictionary is a series of fascinating discussions of various aspects of ideograms. These include a discussion of signs and meanings, an overview of the historical development of signs, as well as sections on ancient American ideograms, the astrological system of symbols, the mystical pentagram, and the signs of the alchemists. Two indexes aid the reader. The Word Index specifies signs with a given name or meaning, along with subject headings. The Graphic Index displays symbols based on their structural features Dictionary of Symbols serves both as a valuable reference on Western cultural history and as a professional tool for those working in design and the arts.
