These took the form of a round-topped stelae, and they were used to mark boundaries. For example, Senusret III used them to mark the boundary between Egypt and Nubia.[83] Because of the prosperity of this period, the lower elite were able to commission statues and stelae for themselves, although these were of poorer artistic quality.[85] Those who commissioned non-royal stelae had the ultimate goal of eternal existence. This goal was communicated with the specific placement of information on the stone slabs similar to royal stelae (the owner's image, offering formula, inscriptions of names, lineage and titles).[86]
