The ancient Egyptians believed that the afterlife was very much like the Egypt that they lived in. Thus, there was a lot work to be done in the home and in the fields.
Shabtis were small figures who would magically come to life and work instead of their 'master' or 'mistress' whenever there was work to be done in the afterlife. Some people had enough shabtis and 'overseers'(to keep the shabtis in order) buried with them so there was one for each day of the year.
These shabtis belonged to a priestess named Henutmehyt.
