working on his father's temple nearly four decades into his own reign. He notes that the only possible explanation for the block's existence at the project is that Senusret III had a 39-year reign, with the final 20 years in coregency with his son Amenemhat III. Since the project was associated with a project of Senusret III, his Regnal Year was presumably used to date the block, rather than Year 20 of Amenemhat III. Wegner interprets this as an implication that Senusret was still alive in the first two decades of his son's reign. Wegner's hypothesis is rejected by some scholars, such as Pierre Tallet and Harco Willems; according to them, it is more likely that such a coregency never occurred, and that the Year 39 control note still refers to Amenemhat III, who may have ordered some additions to Senusret's monuments. Pyramid and complex Senusret's pyramid complex was built north-east of the Red Pyramid of Dashur. It far surpassed those from the early twelfth dynasty in size, grandeur, and underlying religious conceptions. There has been speculation that Senusret was not necessarily buried there, but rather, in his sophisticated funerary complex in Abydos and his pyramid more likely being a cenotaph. Senusret's pyramid is 105 meters square and 78 meters high. The total volume was approximately 288,000 cubic meters. The pyramid was built of a core of mud bricks. They were not made a consistent size implying that standardized moulds were not used. The burial chamber was lined with granite. Above the vaulted burial chamber was a second relieving chamber that was roofed with five pairs of limestone beams each weighing 30 tons. Above this was a third mudbrick vault. The pyramid complex included a small mortuary temple and seven smaller pyramids for his queens. There is also an underground gallery with further burials for royal women. Here were found the treasures of Sithathor and queen Mereret. There was also a southern temple, however this has since been destroyed. Royal statuary Senusret III is well known for his distinctive statues, which are almost immediately recognizable as his. On them, the king is depicted at different ages and, in particular, on the aged ones he sports a strikingly somber expression: the eyes are protruding from hollow eye sockets with pouches and lines under them, the mouth and lips have a grimace of bitterness, and the ears are enormous and protruding forward.
