Detail of the mural painting on the ceiling of the burial chamber, decorated with astronomical motifs on a midnight blue background. The picture shows the constellation Ursa Major represented as a bull walking on a platform supported by the falcon-headed god Anu. Behind the bull is a deity with a disc on his head holding reins that connect the bull to a pole. In front of the bull are the goddess Serket, a falcon, a lion surrounded by stars and a crocodile.
