Sed festival
Twenty labels made of ivory and ebony were found in his tomb, 18 by Flinders Petrie in the spoil heaps left by the less thorough Émile Amélineau. Among these labels are the earliest known depictions of a pharaoh wearing the double-crown of Egypt (see above), as well as running between ritual stele as part of the Sed festival. Also found are seal impressions that provide the earliest confirmed king list.
