This relief detail in the tomb of Kheruef shows a female dancer who performs on the occasion of the First Jubilee (heb sed) festival of Amenhotep III (in year 30 of his reign).
Kheruef was steward of Queen Tiy, the wife of Amenhotep III, and played an important role during festivals.
His (unfinished) tomb (TT 192) can be found in the Asasif Necropolis on the Westbank at Luxor.
It is one of the socalled "Tombs of the Nobles".
