Wrapping the body in a shroud is practice common to many cultures. In Egypt, once the body had been mummified and carefully wrapped with bandages, a large sheet of linen (a shroud) was usually the final stage before the body was placed in the coffin. Sometimes something was written on this shroud, and in the early New Kingdom and Late Period, texts of the Book of the Dead were sometimes written on them.
A number of fragments of such a shroud bearing the name of Senneferi were located in the burial chambers of his tomb in 1998. This material is very fragile and, with no conservator available, little could be done other than to take some representative photos and then pack them as carefully as we could.
Below is a large fragment of the linen shroud, before conservation:
