In ancient Egypt, linen was used for mummification and for burial shrouds. It was also worn as clothing on a daily basis; white linen was worn because of the extreme heat. For example, the Tarkhan dress, considered to be among the oldest woven garments in the world and dated to between 3482 and 3102 BC, is made of linen. Plutarch wrote that the priests of Isis also wore linen because of its purity. Linen was sometimes used as a form of currency in ancient Egypt. Egyptian mummies were wrapped in linen as a symbol of light and purity, and as a display of wealth. Some of these fabrics, woven from hand-spun yarns, were very fine for their day, but are coarse compared with modern linen. When the tomb of the Pharaoh Ramses II, who died in 1213 BC, was discovered in 1881, the linen wrappings were in a state of perfect preservation after more than 3000 years. When the tomb of Tutankhamen was opened, the linen curtains were found to be intact. In the Ulster Museum, Belfast there is the mummy of 'Takabuti' the daughter of a priest of Amun, who died 2,500 years ago. The linen on this mummy is also in a perfect state of preservation.
