Volume Two of Two book set. These two books of very special patterns are fascinating to color and offer tremendous scope for the imagination. Everyone sees something different in them and there are so many different aspects to pick out. These patterns are firmly based on principles that were first discovered by Arabic mathematicians in the 10th century. They have now been investigated by John Martineau and accurately drawn by computer. The most beautiful of the designs have been selected for these two books, the first based on the square and the second on the hexagon.
