Christina Geisen provides for the first time a complete description of the now lost wooden coffin of the royal wife Mentuhotep, which was discovered in Thebes at the beginning of the 19th century. Mentuhotep descended from a Theben family of viziers and she was the wife of king Djehuti. The Book of the Dead and Coffin Text spells that were copied on the inner and outer sites of the coffin build the focus of the examination. Additionally, the publication comprises a description of the artifact and, based upon that, a placement of the piece into the typology of ancient Egyptian coffins, which leaves no doubt that the coffin of Mentuhotep dates to the end of the 13th dynasty (1759-1630 BCE). This result is all the more important as the coffin is the first textual witness of the ancient Egyptian Book of the Dead – longer Book of the Dead spells could only be verified for the 17th dynasty (1625-1539 BCE) so far. Based on the chronological placement of the coffin to the end of the 13th dynasty, the reign of Djehuti has to be dated to the same time – in contrast to the traditional dating to the 17th dynasty. Drawings of the outer sides and a transcription of the hieroglyphic texts are made available to the public for the first time in this publication, which also includes the transliteration and transcription of the hieratic texts preserved on the coffin’s inner sides.
