Celtic Ornament no. 1. Lapidary ornamentation 

"Celtic Ornament no. 1" is a detailed drawing by Owen Jones, a prominent British designer of the 19th century. The artwork is a meticulous study of Celtic knotwork, a style of ornamentation that originated in Ireland and Scotland and was popular in the Middle Ages. The intricate patterns are based on interlocking loops and spirals, creating a visually complex and aesthetically pleasing design. Jones was known for his passion for historical and decorative art, and his drawings of Celtic ornament reflect his interest in reviving and preserving traditional design motifs.
