جبل البركل
Why the Kushites chose to enter Egypt at this crucial point of foreign domination is subject to debate. Archaeologist Timothy Kendall offers his own hypotheses, connecting it to a claim of legitimacy associated with Jebel Barkal. Kendall cites the Victory Stele of Piye at Jebel Barkal, which states that "Amun of Napata granted me to be ruler of every foreign country," and "Amun in Thebes granted me to be ruler of the Black Land (Kmt)". According to Kendall, "foreign lands" in this regard seems to include Lower Egypt while "Kmt" seems to refer to a united Upper Egypt and Nubia.
