Ushabti were servants devoted to working for their deceased owners. In ancient Egyptian religion, the tombs were equipped with small-sized and mummy-shaped figurines with arms crossed on the chest. The use of them was widespread, and their ‘mission’ was to set the deceased free from the necessity of labor in the afterlife.
Sometimes, early ushabtis were made of wax, but most often, clay and wood were used in their production. Later figurines were usually made of much more resistant and durable materials like stone, terracotta, metal, glass, and most frequently, glazed earthenware known as the Egyptian faience (blue-green glazed ushabtis).
While ushabtis manufactured for the rich were often miniature works of art, however, the significant quantities of discovered ushabti figurines were the result of cheap artistry, based on single molds with a few details, only. Archaeologists frequently discovered boxes full of ill-shaped and uninscribed porcelain figures buried in the tombs with the dead.
These small workers were stored, but always ready to answer the call of the gods to work in the next world for the owner of the tomb.
The use of the ushabti figures continued down to the Roman period and the tradition was widespread. Over the centuries, the number and quality of these artifacts changed. In the early Middle Kingdom, it was common to place two pieces of carefully made figurines in the grave. Later, in the Late period, ancient Egyptians decided that the deceased needed many more workers who accompanied them to the afterlife, and it was not uncommon to put up to one thousand of these artifacts in a tomb.
During the 18th Dynasty of Thutmose IV, they began to be fashioned as servants with sacks, baskets, and agriculture tools. With such equipment, the ushabti-workers could magically replace the dead owner when the gods requested him to undertake physical work such as irrigation and cultivation of fields, clearing irrigation channels, etc.
Even royal ushabtis were often depicted holding a hoe or a pick and carrying a basket on shoulders.
The ushabtis were usually covered with texts, and included in grave equipment from the Middle Kingdom (21st-18th centuries BC) to the Ptolemaic period (332–30 BC). During the New Kingdom (1539–1075 BC), the figurines were made to resemble the tomb’s owner, and were fashioned in the form of a mummy, bearing the owner’s name.
