AN ANCIENT EGYPTIAN PILLOW was preserved with Dead Sea wax:

Unusual Ancient Egyptian Pillow Analyzed

April 5, 2006 — Most ancient Egyptian pillows were rather uncomfortable-looking headrests carved out of wood, ivory and stone, but scientists have just analyzed a 4,000-year-old Egyptian pillow made out of woven plant fibers that were encased in a wax coating.

The rare artifact, which dates to 2055-1985 B.C., suggests Cleopatra and other well-known ancient Egyptians may have snoozed on relatively fluffy pillows that perhaps biodegraded over time, leaving the hard headrests for modern archaeologists to find.

"If sleeping on fiber pillows and bedding occurred, it has not survived well or at all in the archaeological record of the ancient Near East," said Andy Gize, Judith Seath and Rosalie David, whose research will be published in next month's Journal of Archaeological Science.

Since the wax on the pillow appears to have come from a Dead Sea petroleum residue, the artifact also could indicate that a community of "foreigners" brought knowledge of petroleum processing and pillow making into the Sedment el-Gebel region of the western Nile Valley.
