エジプト古王国
The practice of using ushabtis originated in the Old Kingdom of Egypt (c. 2600 to 2100 BCE), with the use of life-sized reserve heads made from limestone, which were buried with the mummy. Most ushabtis were of minor size, and many produced in multiples – they sometimes covered the floor around a sarcophagus. Exceptional ushabtis are of larger size, or produced as a one-of-a-kind master work.
