Penthu (Ancient Egyptian: pnṯw)[1] was an Egyptian noble who bore the titles of sealbearer of the King of Lower Egypt, the sole companion, the attendant of the Lord of the Two Lands, the favorite of the good god, king's scribe, the king's subordinate, First servant of the Aten in the mansion of the Aten in Akhetaten, Chief of physicians, and chamberlain.
He was originally Chief Physician to Akhenaten, but may have survived the upheavals of the end of the Amarna Period, and served under Ay, after being Vizier under Tutankhamun.
The inscription is explicitly dated to Year 16, 3rd month of Akhet, day 15 of the reign of Akhenaten.
Due his position as a chief priest within the Aten priesthood, it is unlikely to be a coincidence that he would have been placed in charge of quarrying stone for this temple.
[5] The inscription was first published in 2012 by Athena van der Perre and established that Nefertiti was still alive in the second last year of Akhenaten's reign--his Year 16--and makes it probable she ruled Egypt as the female king Neferneferuaten--just prior to Tutankhamun's reign.
