Here is more on the ancient story of Horus (Heru) and Seth (Set), in which the two gods have sex with one another. Regardless of how one chooses to interpret the way the ancient Egyptians perceived homosexuality, the fact remains that this story, whether it was written by divine inspiration, or by mere mortals, contains a retelling of a sexual act between two males, written thousands of years ago in Africa. The fact that the story was told regarding the beginnings of the Egyptian civilization attests to its age. The additional fact that ancient Egypt existed for nearly 3000 years, and this story was not deleted from its lengthy records of the gods, attests to its importance to the Egyptians. It also attests to the existence and knowledge of sexual relations between people of the same gender, dating back thousands of years on the continent of Africa. This alone would annihilate any claim that homosexuality was imported to Africa by Europeans during the slave trade and colonial period.

Conflict of Horus and Seth – One famous story in ancient Egypt describes an extended conflict between the god Osiris and Seth, his rival brother, who murders Osiris and then seeks to remove Horus, Osiris’ son and heir, with his claim to be king of the gods. This narrative, usually referred to as “The Contendings of Horus and Seth,” exists in different versions and dates back to the early Middle Kingdom (2040-1674 B.C.), with origins that are probably older.5 The earliest longest version, dated c. 1160 B.C., late in 20th Dynasty in the New Kingdom,6 describes how “Seth said to Horus: ‘Come let us spend a pleasant hour at my house.’ Horus answered, ‘With pleasure, with pleasure.’ When it was evening a bed was spread for them and they lay down. During the night Seth made his penis stiff and he placed it between the loins of Horus. Horus put his hands between his loins and caught the sperm of Seth.7 Then Horus went to his mother, Isis [and said]: ‘Help me…! Come, see what Seth has done to me.’ And he opened his hand and let her see Seth’s semen. With a scream she took her weapon and cut off his hand and threw it in the water, and conjured up for him a hand to make up for it.”8 Then Isis helped Horus ejaculate and smeared his sperm over some lettuce, which was Seth’s favorite vegetable and which she then gave to him to eat. Later, when Seth boasted to the Ennead (the nine gods judging the conflict) that he had done the “work of a male [warrior]”9 on Horus, the gods “screamed aloud, and belched and spat in Horus’ face.” Wolfhardt Westendorf thinks that the Egyptians looked upon semen as poison when taken into the body in the wrong way – yet Seth did not die here. Still, the gods apparently felt that for Horus to be used like a woman sexually was so incompatible with kingship that they erupted with contempt.10 Seth’s act is usually interpreted as one of dominance and aggression, yet as Dominic Montserrat points out, the story is more complex, because here: (1) Two males, comparatively the same age (adults) and same status (gods), lie down for sexual play. (2) Both rivals are able to penetrate the other, in some way, and therefore may be looked upon as equals. (3) Horus willingly consents to have sexual relations with Seth (although not anal intercourse), who physically desires him (“sweet to his heart”) and unabashedly makes his request known.11
An earlier but shorter version, dated c. 2000 B.C.,12 from the 12th Dynasty in the Middle Kingdom and from Lahun (Kahun), describes what happened a little differently: “The divine person of Seth said to the divine person of Horus: ‘How beautiful are your buttocks, how vital! […] Stretch out your legs …’13 And the Person of Horus said: ‘Watch out; I shall tell [this]!’” Then he ran and told his mother Isis, that Seth desired to sodomize him. “And she said to him: ‘Beware! Do not approach him about it! When he mentions it to you another time, then you shall say to him: “It is too painful for me entirely, as you are heavier than me. My strength [backside] shall not support your strength [erection]…”’14 Then when he gives you his strength, place your fingers between your buttocks. … Lo, he will enjoy it exceedingly (?). [Keep] this seed which has come forth … without letting the sun see it…”15 Later, Isis threw Seth’s semen into a nearby stream, then spread some of Horus’ semen on lettuce and gave it to Seth to eat. Later, when Seth boasted to the gods that he had sexually taken Horus, the youth denied it. To settle the argument, the gods called forth the seed of both. The seed of Seth answered from the water into which Isis had thrown it, while the seed of Horus came forth from Seth’s forehead in the form of a golden disk, which was grabbed by the moon god Thoth to become his symbol.16
This story, of the family of Osiris, who was looked upon as the first human king of Egypt,17 suggests that from the earliest period for a male (god or human) to take, or be forced into, a woman’s role and be anally penetrated was looked upon as humiliating and shameful.18 Yet, at the same time, homosexual desire was known and spoken of openly; and men knew of and some engaged in homosexual play in bed, apart from the degrading act. For Horus to be penetrated was a frightening prospect; yet at the same time his semen in Seth brought benefit to the moon god. So, the signals are rather mixed. Actually Seth only fell into disfavor in the 8th century B.C., when his castration and incineration began to be celebrated in hymns, while earlier kings worshipped him as the god of storms and violence, including the Hyksos rulers in Second Intermediate Period (c.1674-1553 B.C.) and Seti and Ramses in the New Kingdom (13th century B.C.). Only much later did the valiant god become a vile demon.19
The full excerpted translation of the portion of the story dealing with the two gods having sex reads:
"Said the Ennead: "Let Horus and Seth be summoned in order that they may be judged."
Then they were brought before the Ennead. Said the Universal Lord before the Great Ennead to Horus and Seth: "Go and obey what I tell you. You should eat and drink so that we may have (some) peace. Stop quarreling so every day on end."
Then Seth told Horus: "Come, let's make holiday in my house."
Horus told him: "I'll do so, surely, I'll do so, I'll do so."
Now afterward, (at) evening time, bed was prepared for them, and they both lay down. But during the night, Seth caused his phallus to become stiff and inserted it between Horus's thighs. Then Horus placed his hands between his thighs and received Seth's semen. Horus went to tell his mother Isis: "Help me, Isis, my mother, come and see what Seth has done to me."
And he opened his hand(s) and let her see Seth's semen. She let out a loud shriek, seized the copper (knife), cut off his hand(s) that were equivalent. Then she fetched some fragrant ointment and applied it to Horus's phallus. She caused it to become stiff and inserted it into a pot, and he caused his semen to flow down into it.
Isis at morning time went carrying the semen of Horus to the garden of Seth and said to Seth's gardener: "What sort of vegetable is it that Seth eats here in your company?"
So the gardener told her: "He doesn't eat any vegetable here in my company except lettuce."
And Isis added the semen of Horus onto it. Seth returned according to his daily habit and ate the lettuce, which he regularly ate. Thereupon he became pregnant with the semen of Horus. So Seth went to tell Horus: "Come, let's go and I may contend with you in the tribunal."
Horus told him: "I'll do so, surely, I'll do so, I'll do so."
lettuce: was considered an aphrodisiac, connected to Min, god of fertility
They both went to the tribunal and stood in the presence of the Great Ennead. They were told: "Speak concerning yourselves."
Said Seth: "Let me be awarded the office of Ruler, l.p.h., for as to Horus, the one who is standing (trial), I have performed the labor of a male against him."
The Ennead let out a load cry. They spewed and spat at Horus's face. Horus laughed at them. Horus then took an oath by god as follows: "All that Seth has said is false. Let Seth's semen be summoned that we may see from where it answers, and my own be summoned that we may see from where it answers."
Then Thoth, lord of script and scribe of truth for the Ennead, put his hand on Horus's shoulder and said: "Come out, you semen of Seth."
And it answered him from the water in the interior of the marsh. Thoth put his hand on Seth's shoulder and said: "Come out, you semen of Horus."
Then it said to him: "Where shall I come from?"
Thoth said to it: "Come out from his ear."
Thereupon it said to him: "Is it from his ear that I should issue forth, seeing that I am divine seed?"
Then Thoth said to it:"Come out from the top of his head."
And it emerged as a golden solar disk upon Seth's head. Seth became exceeding furious and extended his hand(s) to seize the golden solar disk. Thoth took it away from him and placed it as a crown upon his (own) head. Then the Ennead said: "Horus is right, and Seth is wrong."
