Senusret III
The dating of Siese is uncertain. For a long time it has been assumed that he was in office under king Amenemhat II, as his mastaba is close to that of this king. However, in his mastaba appear scenes showing single family members sitting on the ground with a small pile of offerings in front of them. This type of scene is only attested from the reign of king Senusret III onwards. Furthermore, the realistic depiction of Siese's face had parallels in on reliefs in he mastaba of Sobekemhat, who dates under Senusret III. These observations indicate that Siese dates under this king.
