[1] 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.

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 Amheida the Dakhla Oasis.

This graffito would have been carved prior to Piye's Nubian conquest of Egypt in his 20th Year—by which time both Takelot III and Rudamun had already died.

However, new evidence on the Wadi Gasus graffito published by Claus Jurman in 2006 has now redated the carving to the 25th dynastic Nubian period entirely—to Year 12 of Shabaka and Year 19 of Taharqa rather than to the 23rd dynastic Libyan era—and demonstrates that they instead pertain to Amenirdis I and Shepenupet II respectively based on palaegraphic and other evidence collated by Jurman at Karnak rather than the Nubian Amenirdis I and the Libyan Shepenupet I, daughter of Osorkon III.

Jurman notes that no evidence from the innermost sanctuary of the chapel of Osiris Heqadjet at Karnak shows Shepenupet I associated with Piye's daughter, Amenirdis I.

Finally, the author noted that the Royal Treasurer Djedmontuiufankh, son of Aafenmut II, lists his family genealogy on the opposite side of this papyrus.

(Payraudeau: 84-85) This specific list of his family tree is given: An Aafenmut, a scribe of the Chief Treasurer, was buried under Osorkon I (bracelets on his Mummy bore this king's prenomen).

As an aside, the author believed that Nile Quay Text No.45—which, according to Gerardus Broekman in JEA 88(2002), records either Year 17, 18 or 25 of an anonymous Theban king who ruled after Shoshenq III—may perhaps be ascribed to Takelot III based on the evidence of Papyrus Berlin 3048.

[16] He was ultimately succeeded in power by his younger brother Rudamun, who was another son of Osorkon III rather than by any of his 3 known sons: the Prince/High Priest Osorkon F, a Prince Ihtesamun who is known from the stela of his grandson Ankhfenmut in Croydon Central Library and, finally, the Second Prophet of Amun, Djedptahefankh D who is attested in statue Tübingen 1734 and in stela CG 41006 of his great-granddaughter Nakhtbasteru.
