Masks of this type rose to popularity in the Late Period of Ancient Egypt. They likely had both a decorative and symbolic role, as the burial of the dead in Ancient Egypt was an elaborate and ritualised process. Their unnaturalistic style and the similarities between beaded mummy masks in general make it unlikely that they were modelled after the face of the deceased individual. They seem to have more likely been generic images of a dead human face as the absence of expression and the blue-greenish skin complexion could indicate. However, such masks have also been interpreted as visual representations of the god Osiris – himself also a dead being – frequently depicted in the tombs with an identical skin-colour. Winged scarabs were usually modelled in faience and placed as pectoral embellishment on the chest of the mummy. In this case, the scarab, symbol of re-birth and regeneration, has been sewed together with the mummy mask. According to mythology, the Four Sons of Horus each were attributed a different organ to protect. For Imsety, the liver; for Duamutef, the stomach; for Hapi, the lungs; and for Qebehsenuef, the intestines. As the heart was believed to be the resting place of the soul, it was not removed from the deceased. The brain, on the other hand, was thought to be inconsequential, so was scrambled to liquid, removed with metal hooks and then discarded. The four protected organs were removed from the body, embalmed, and then stored in their corresponding jar.
