from Karnak, Koptos and Heliopolis. Economic decline Over the period spanning the reigns of Ramesses VI, VII and VIII, prices of basic commodities, in particular grain, rose sharply. With Egypt's economy getting weaker, Ramesses VI turned to usurping the statues and monuments of his forebears, frequently plastering and then carving his cartouches over theirs, in particular those of Ramesses IV which figured prominently along the processional routes in Karnak and Luxor. In other examples, he usurped a statue of Ramesses IV, columns of texts inscribed by Ramesses IV on an obelisk of Thutmose I in Karnak, and the tomb of Ramesses V. Kitchen warns not to over-interpret these usurpations as signs of antagonism on behalf of Ramesses VI with respect to his older brother and nephew. The usurpations were not thorough but were rather targeted to the most prominent places, where Ramesses VI's cartouches would be most visible. Besides, Ramesses VI did leave cartouches of Ramesses IV intact in many places, including in places where both his name and that of his brother feature close to one another such as in the Medinet Habu temple of Ramesses III, so that the hypothesis of a damnatio memoriae—whereby all references to someone are systematically eliminated so as to remove this person from memory and history—can be eliminated. A possible evidence for genuine architectural works on Ramesses VI's behalf is found in Memphis, where an inscription on a granite gateway cornice of the temple of Ptah claims that he erected a great pylon of fine stone. Ramesses VI then boasts of "covering all the land with great monuments in my name [...] built in honour of my fathers the gods". Overall, the Egyptologist Amin Amer characterises Ramesses VI as "a king who wished to pose as a great pharaoh in an age of unrest and decline". Dilution of power High officials Some high officials of Ramesses VI are known, such as his finance minister and overseer of the treasury Montuemtawy who was in office since the end of Ramesses III's reign; the vizier Neferronpe in office since Ramesses IV's time on the throne; his son the vizier Nehy; Amenmose the mayor of Thebes and the king's butler Qedren. To the south, the troop commander of Kush was Nebmarenakhte and the administrator of Wawat—the land between the first and second cataracts of the Nile—mayor of Anîba and controller of the Temple of Horus at
