Celtic Design, A Beginner's Manual by Aidan Meehan
Celtic Design, Knotwork - The Secret Methods of the Scribes
Thames and Hudson 1991 ISBN 9780500276297 and 9780500276303
These two soft-covered, 160 page books are complementary. If you must buy only one, make it 'A Beginner's Manual', but you will do better with the pair. The author has for 20 years helped lead the revival of this art form. His masterly black and white drawings, and neat calligraphic text, simplify it for the rest of us. Book 1 shows how to construct dot-ta-dot and compass-work knot layouts: also how to draw and embellish Celtic style letters. Book 2 is a fuller treatment of knot patterns, including how to design borders, panels and other layouts. Celtic artwork now adorns and sells jewellery, greetings cards, dress fabrics, book jackets and pottery. Many graphic designers and craft workers have added it to their repertoires. If you fancy joining them, I can highly recommend these two books for starters.
