Thutmose I
In 1987, Luc Gabolde published an important study that statistically compared the number of surviving scarabs found under Thutmose I, Thutmose II and Hatshepsut. While monuments can be usurped, scarabs are so small and comparatively insignificant that altering their names would be impractical and without profit; hence, they provide a far better insight into this period. Hatshepsut's reign is believed to have lasted for 21 years and 9 months. Gabolde highlighted, in his analysis, the consistently small number of surviving scarabs known for Thutmose II compared to Thutmose I and Hatshepsut respectively; for instance, Flinders Petrie's older study of scarab seals noted 86 seals for Thutmose I, 19 seals for Thutmose II and 149 seals for Hatshepsut while more recent studies by Jaeger estimate a total of 241 seals for Thutmose I, 463 seals for Hatshepsut and only 65 seals for Thutmose II. Hence, unless there was an abnormally low number of scarabs produced under Thutmose II, this would indicate that the king's reign was rather short-lived. On this basis, Gabolde estimated Thutmose I and II's reigns to be approximately 11 and 3 full years, respectively. Consequently, the reign length of Thutmose II has been a much debated subject among Egyptologists with little consensus given the small number of surviving documents for his reign.
