Similarities can be seen in Tripilja culture in Ukraine, displayed in the Ukraine pavilion at the Expo 2010 in Shanghai, China.[25] Also, the interlocking design is found in artifacts of the European Iron Age.[4][26]
While this design appears to become a standard ornamental motif in Iron-Age Celtic culture by the 3rd century BC, found on a wide variety of artifacts, it is not clear what symbolic value was attached to it.[27][28] Unlike the Chinese symbol, the Celtic yin-yang lack the element of mutual penetration, and the two halves are not always portrayed in different colors.[29] Comparable designs are also found in Etruscan art.[5]
