"When this book first appeared it was hailed as a 'veritable grammar of ornament.' It is certainly an indispensable reference book and practical textbook for the art student and craftsman seeking simple constructional methods for laying out complex ornamental schemes. The entire chronology of symbols is embraced from spirals through chevrons, step patterns and keys to knotwork interlacings which are unique to this particular Celtic School. There are also sections dealing with zoomorphics, plant and human forms, authentic Celtic lettering, initials and terminals and examples of applications in knitwear, carpets, ceramics and other areas in which the author pioneered in his day." --Back cover.
