Sumo sacerdote de Amón
Takelot I's authority was not fully recognised in Upper Egypt, and Harsiese A, or another local Theban king, challenged his power there. Several Nile Level Texts at Thebes mention two sons of Osorkon I—namely, the High Priests of Amun Iuwelot and Smendes III in Years 5, 8 and 14 of an anonymous king who can only be Takelot I, since Takelot I was their brother.
