"It may be observed that the page before us contains almost all the varieties of design to be found in Celtic art. These are usually spoken of as twofold: first, arbitrary or geometrical—of which there occur on the page before us the divergent pattern known as the trumpet-pattern, the triquetra, the interlaced curved bands, the knot, and the designs formed of eight lines; secondly, patterns derived from natural forms—foliage, birds, reptiles, fish, quadrupeds, imaginary or monstrous animals, and man." (Vetusta Monumenta, Society of Antiquaries, London, 1869).
