Celtic Art -The Methods of Construction by George Bain
Courier Corporation, 2013 (orig. 1951) ISBN 9780486317441
Royal College of Art student, book illustrator and ultimately an art master, the author acquired a unique knowledge of knot patterns in Celtic art; then set about showing students how to recreate these complicated creations by the systematic repetition of a few simple guidelines. If you need to draw anything from a simple overhand or thumb knot to the elaborate knot engravings of Albrecht Durer and Leonardo da Vinci, this book will show you how. In simple stages, with just a ruler, some graph paper, and pencil and eraser, you could also - after browsing through George Bain’s work - create your own original knot designs.
