Meanders are common decorative elements in Greek and Roman art. In ancient Greece they appear in many architectural friezes, and in bands on the pottery of ancient Greece from the Geometric Period onwards. The design is common to the present-day in classicizing architecture. The meander is a fundamental design motif in regions far from a Hellenic orbit: labyrinthine meanders (“thunder” pattern) appear in bands and as infill on Shang bronzes, and many traditional buildings in and around China still bear geometric designs almost identical to meanders. There is a possibility that meanders of Greek origin may have come to China during the time of the Han Dynasty by way of trade with the Greco-Bactrian Kingdom, but space-filling curves have a long history in the region, extending back to Zhukaigou Culture and Xiajiadian Culture motifs over 2,000 years earlier.
