caption: The image shows a black and white engraving of two men, one of whom is holding a celtic knot in his hand. The man on the left is wearing a long robe and has a stern expression on his face, while the other man has a more serious expression. The knot is intricately detailed and appears to be made of metal, with a circular pattern of interlocking loops and knots. The text at the bottom of the image reads "Celtic Knot".
