Depicted in the 8th to 10th century Book of Kells, the two swans are animals that mate for life. They show the unity between two people as a circle; a never ending bond that transcends all. Two as in one mind, thought and understanding. A pledge never broken. Because this zoomorphic design is so complex it shows better in larger sizes and is available in the 1 1/4 and 1 1/2 sizes only. I have made this pattern in a smaller size , but the complexity of the pattern makes it had to read .
