[3] Following a proposal (first suggested to him by Pieter Gert van der Veen in 1984), the British Egyptologist Aidan Dodson in 1993 supported the new king's existence by demonstrating that the earlier Hedjkheperre Shoshenq bore simple epithets in his titulary, whereas the later Hedjkheperre Shoshenq's epithets were more complex.

[4] Rohl and Dodson's combined arguments for the existence of a new 22nd Dynasty Tanite king called Hedjkheperre Shoshenq IV are accepted by Egyptologists today, including Jurgen von Beckerath and Kitchen – the latter in the preface to the third edition of his book on The Third Intermediate Period in Egypt.

[7] These two epithets were only gradually employed by the 22nd Dynasty pharaohs, starting from the reign of Osorkon II.

Rohl had already pointed out in 1989 that the cartouches of a Hedjkheperre Shoshenq appear on a stela (St. Petersburg Hermitage 5630) dated to Year 10 of the king.

[11] In the Tanite tomb's debris, several fragments were found from one or two canopic jars bearing the cartouches of a Hedjkheperre Shoshenq.
