Usermaatre Setepenamun Takelot III Si-Ese (reigned 774–759 BC) was Osorkon III's eldest son and successor. Takelot III ruled the first five years of his reign in a coregency with his father, according to the evidence from Nile Quay Text No.13 (which equates Year 28 of Osorkon III to Year 5 of Takelot III), and succeeded his father as king the following year. He served previously as the High Priest of Amun at Thebes. He was previously thought to have ruled Egypt for only 7 years until his 13th Year was found on a stela from Ahmeida in the Dakhla Oasis in 2005. Reign length Takelot is attested by several documents: a donation stela from Gurob which calls him "The First Prophet of Amun-Re, General and Commander Takelot," a stone block from Herakleopolis which calls him 'the Chief of Pi-Sekhemkheperre' and king's son by Tentsai, Quay Text No.13, as noted above, and Quay Text No.4 which records his Year 6. A graffito on the roof of the Temple of Khonsu which records his Year 7, was long believed to be his Highest Year date. However, in February 2005, a hieratic stela from Year 13 of his reign was discovered by a Columbia University archaeological expedition in the ruins of a Temple at the Dakhla Oasis. Their subsequent analysis of this dated document conclusively established this king's identity as Takelot III. This document—which measures "between 42-48 cm wide; between 47-51 cm high; [and] between 10-16 cm thick"—has now been published in JEOL 39 (2006) by Dr. Olaf Kaper and Robert Demarée. Part of the abstract for their article is given below: ...The stela belongs to a group of finds documenting the temple of the God Thoth...[in the western part of the Dakhla Oasis]...during the Third Intermediate Period. One block of temple decoration was found in the name of king Petubastis (I), and the stela under discussion was set up in the temple to which this block belonged. The stela's principal text has five lines, in which the date of the stela is given as Year 13 of Takeloth III (c. 740 BCE), as well as the name of the god Thoth of SA-wHAt, the local deity. The stela records a land donation to the temple on the part of the local governor, chief of a Libyan tribe, and it concludes with a list of eleven priests who are beneficiaries of this donation....Another
