The Stele of Ankh-ef-en-Khonsu (also known as the Stele of Revealing) is a painted, wooden offering stele located in Cairo, Egypt. It was discovered in 1858 by François Auguste Ferdinand Mariette at the mortuary temple of the 18th Dynasty Pharaoh Hatshepsut, located at Dayr al-Bahri. It was originally made for the Montu-priest Ankh-ef-en-Khonsu i, and was discovered near his coffin ensemble of two sarcophagi and two anthropomorphic inner coffins. It dates to circa 680–70 BCE, the period of the late 25th Dynasty/early 26th Dynasty. Originally located in the former Bulaq Museum under inventory number 666, the stele was moved around 1902 to the newly opened Egyptian Museum of Cairo (inventory number A 9422; Temporary Register Number 25/12/24/11), where it remains today.
