), Imyremeshaw was attested by a pair of colossi dedicated to Ptah "He who is south of his wall, Lord of Ankhtawy" (rsy-ínb=f nb ˁnḫt3wy).

In the 19th Dynasty, during the New Kingdom, both colossi were moved to Pi-Ramesses by Ramses II who also had his name inscribed on them, together with a further dedication to Seth.

The fragment however is uninscribed and Davies' identification of the owner of the statuette as Imyremeshaw is based solely "on grounds of provenance".

The exact duration of the reign of Imyremeshaw is mostly lost in a lacuna of the Turin canon and cannot be recovered, except for the end: "[and] 4 days".

Ryholt proposes that the combined reigns of Imyremeshaw and his two successors Sehetepkare Intef and Seth Meribre amount to about 10 years.

Even though the king's name is lost in a lacuna, Ryholt's analysis of the papyrus only leaves Imyremeshaw and Sehetepkare Intef as possibilities.

[1] The exact circumstances of the end of Imyremeshaw's reign are unknown but the fact that his successor Sehetepkare Intef did not use filiative nomina points to a non-royal birth.
