 A degree of uncertainty affects the ownership of these artifacts since Amenhotep III's prenomen was Nebmaatre as well.However, the axe-head can be dated to the late Second Intermediate Period based on stylistic grounds and provenance while according to Flinders Petrie the amulet is of too rough a workmanship to be attributable to Amenhotep III.Instead Petrie suggested that the amulet be attributable to Ibi, an obscure ruler of the late 13th Dynasty whose prenomen is partially preserved in the Turin canon as ""[...]maatre"".
