Skull cup

A skull cup is a drinking vessel or eating bowl made from an inverted human calvaria that has been cut away from the rest of the skull. The use of a human skull as a drinking cup in ritual use or as a trophy is reported in numerous sources throughout history and among various peoples, and among Western cultures is most often associated with the historically nomadic cultures of the Eurasian steppe.

The (currently) earliest directly dated skull cup at 14,700 BC comes from Gough's Cave, Somerset, England. Skulls used as containers can be distinguished from plain skulls by exhibiting cut-marks from flesh removal and to produce a regular lip.

According to Herodotus' Histories, Scythians killed their enemies and made their skulls into drinking cups. The oldest record in the Chinese annals of the skull-cup tradition dates from the last years of the Spring and Autumn period, when the victors of the Battle of Jinyang in 453 BC made the skull of their enemy into a winecup. Later, the Records of the Grand Historian recorded the practice among the ancient Xiongnu of present-day Mongolia. Laoshang (or Jizhu), son of the Xiongnu chieftain Modu Chanyu, killed the king of the Yuezhi around 162 BC, and in accordance with their tradition, "made a drinking cup out of his skull". According to the biography of the envoy Zhang Qian in Han shu the drinking cup made from the skull of the Yuezhi king was later used when the Xiongnu concluded a treaty with two Han ambassadors during the reign of Emperor Yuan (49-33 BC). To seal the convention, the Chinese ambassadors drank blood from the skull cup with the Xiongnu chiefs.
