The deliberate erasures or mutilations of the numerous public celebrations of her accomplishments, but not the rarely seen ones, would be all that was necessary to obscure Hatshepsut's accomplishments. Moreover, by the latter half of Thutmose III's reign, the more prominent high officials who had served Hatshepsut would have died, thereby eliminating the powerful religious and bureaucratic resistance to a change in direction in a highly stratified culture. Hatshepsut's highest official and closest supporter, Senenmut, seems either to have retired abruptly or died around Years 16 and 20 of Hatshepsut's reign, and was never interred in either of his carefully prepared tombs. According to Tyldesley, the enigma of Senenmut's sudden disappearance "teased Egyptologists for decades" given "the lack of solid archaeological or textual evidence" and permitted "the vivid imagination of Senenmut-scholars to run wild" resulting in a variety of strongly held solutions "some of which would do credit to any fictional murder/mystery plot." In such a scenario, newer court officials, appointed by Thutmose III, also would have had an interest in promoting the many achievements of their master in order to assure the continued success of their own families.
