Detail of the wall painting on the ceiling of the burial chamber, decorated with astronomical motifs on a midnight blue background. The detail represents the constellation of the Hippopotamus, a representation of the stars of the northern sky, although a more certain identification is not possible. To the side is 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.
