in this video [2:47] Met curator Adela Oppenheim on emptiness in Pectoral and Necklace of Sithathoryunet with the Name of Senwosret II dating from Egypt's Middle Kingdom, c. 1887-1878 B.C.E. This cloisonne pectoral is inlaid with 372 carefully cut pieces of semiprecious stones. The heraldic design is replete with symbolism. Zigzag lines on the base bar represent the primordial waters out of which the primeval hill emerged. Each of the falcons, symbols of the sun god, clasps a circular hieroglyph meaning "encircled," thus declaring the solar deity's supreme power over the universe.
