Herman Hoeh asserted in his presently discredited Compendium of World History that one ancient ruler of Egypt was a cannibal, namely Unis, who is also referred to as Unas, the last king of Dynasty V.
With Unis the dynasty comes to a catastrophic end. (He was a contemporary of the Pharaoh who perished at the Red Sea.) The king died the night of the Passover. Unis was a firstborn' He was also a cannibal! After Moses left Egypt, he commenced the frightful practice of eating the firstborn of his enemies. That is one of the reasons God slew the firstborn of Egypt. From the pyramid-tomb of Unis one may read this horrible account of his life, his blasphemous claims, and his deeds.
"Behold, Unas hath arrived at the height of heaven .... Ra is on one side and Horus is on the other, and Unas is between them .... Unas hath weighed his word with the hidden god who hath no name, on the day of hacking in pieces the firstborn .... Unas devoureth men .... He ... cutteth off hairy scalps ... the cordmaster hath bound them for slaughter. Khonsu the slayer of ... hath cut their throats and drawn out their inward parts, for it was he whom Unas sent to drive them in: and Shesem hath cut them in pieces and boiled their members in his blazing cauldrons. Unas hath eaten their words of power, and he hath swallowed their spirits; the great ones among them serve for his meal at daybreak, the lesser serve for his meal at eventide, and the least among them serve for his meal at night. The old gods and the old goddesses become fuel for his furnace. The mighty ones in heaven shoot out fire under the cauldrons which are heaped up with the haunches of the firstborn; and he that maketh those who live in heaven to revolve around Unas hath shot into the cauldrons the haunches of their women of the gods in visible form. UNAS IS THE FIRSTBORN OF THE FIRSTBORN existence is ... and the offerings made unto him are more than those made unto the gods ..." (from E. A. Wallis Budge's "A History of Egypt", vol. II, pages 83-88.) Compare King Unis and his blasphemous claims with II Thessalonians 2:3-4. A remarkable analogy. (Herman Hoeh, Compendium of World History, Volume 1, Chapter 3.)
Hoeh was wrong. This hymn for Unas, which is called the Cannibal Hymn, was an allegory.
... the hymn is best understood as a mythologization of butchery ritual. The sacrifice of a bull was a key element in many Egyptian religious ceremonies. In the Cannibal Hymn, it is the gods who are butchered, cooked and eaten by the king, so that he may absorb and deploy their powers to assist him in his resurrection and apotheosis after death.
