as well as for aesthetic reasons. It was usually made of galena, giving a silvery-black color; during the Old Kingdom, green eye-paint was also used, made from malachite. Egyptian women painted their lips and cheeks, using rouge made from red ochre. Henna was applied as a dye for hair, fingernails and toenails, and perhaps also nipples. Creams and unguents to condition the skin were popular, and were made from various plant extracts. Music On secular and religious occasions, music played an important part in celebrations. Musicians, playing instruments such as the castanets and flute, are depicted on objects from the Predynastic Period. A wide range of percussions, wind and string instruments were known to the ancient Egyptian. They include rattles, clappers, drums, tambourines and the sistrum; pipes, flutes and trumpets; and harps (particularly popular at feasts). The lyre and lute were introduced from the Levant. Musical notation is not attested until the early Ptolemaic Period. Groups of musicians, either mixed gender or female only, are known from the Old Kingdom. Women singers and sistrum-players had an important role in temple cults, especially those of Hathor and Isis. Tomb decoration from all periods indicates that, as today, groups of workers sang to generate a sense of solidarity and to maintain their enthusiasm. Sistrum A sistrum (plural: sistra) is a rattle used in religious ceremonies, especially temple rituals, and usually played by women. Called a "seshsehet" in Egyptian, the name imitates the swishing sound the small metal disks made when the instrument was shaken. It was closely associated with Hathor in her role as "lady of music", and the handle was often decorated with a Hathor head. Two kinds of sistrum are attested, naos-shaped and hoop-shaped; the latter became the more common. Funerary art Coffins The earliest purpose-built funerary containers for bodies were simple rectangular wooden boxes, attested in the 1st Dynasty. A coffin swiftly became an essential part of the burial equipment. Known euphemistically as the "lord of life", its primary function was to provide a home for the Ka and to protect the physical body from harm. In the 4th Dynasty, the development of longer coffins allowed the body to be buried fully extended (rather than curled up on its side in a foetal position). At the end of the Old Kingdom, it became customary once more for the body to be laid on its side. The side of the
