Rishi coffins
Around 1650 BCE rishi coffins were popular in the city of Thebes. These coffins were distinctive because the bodies portrayed on the front were covered with feathers from shoulders to feet. These feathers represented the wings of Isis and Nephthys.
During the New Kingdom, coffins and mummy cases could be purchased ready-made. Once purchased, the owner’s name and titles could be filled in the blanks left in the inscriptions. The ready-made mummy cases were created by molding the container around disposable cores of mud and straw. Per the deceased’s wealth at this time, the deceased could be buried in either one, two, or three different coffins.
