The biblical narrative of Isaac’s sacrifice is unsettling from any point of view. God commands Abraham to kill his own son, Isaac. Without questioning, Abraham obeys. He rises early, prepares the fire, carries the wood, and leads his son to the designated place. Only at the very last moment, as Abraham’s hand is raised with the knife over his son, does a divine voice stop him: “Do not lay a hand on the boy!” A ram appears, caught in the thicket, provided by providence as a substitute.
Traditionally, this intervention has been interpreted as the successful passing of a test: God did not truly desire the sacrifice, only the demonstration of obedience. But this reading raises a disturbing paradox. For God, who would later command “thou shalt not kill,” here demands exactly that.
The paradox dissolves once we notice whom the commandment protects. “Thou shalt not kill” expresses an equality between peers that is not extended to children. Abraham argued with God earlier in Genesis to save the innocent people of Sodom — strangers to him — but here he obeys silently. God has made Abraham a promise: “I will multiply your seed.” So, after the knife comes down on the ram, Abraham’s next act is to procure Isaac a wife, dispatching his servant to fetch Rebekah.
Greek mythology tells the same story about a daughter. Agamemnon has killed a deer sacred to Artemis, and the goddess stills the winds until he pays for it with Iphigenia. He cannot face the act directly, so he deceives his wife and daughter with a stratagem: the girl is told she is to marry Achilles. Sacrifice and marriage overlap perfectly, because they are the same transaction — the daughter as the property of the father, transferred to another authority, just as Helen had been transferred to Agamemnon’s brother, Menelaus. Indeed, this is why Agamemnon’s army needs to sail: to recover a woman who was given to one man and taken by another. The Trojan war is itself a dispute over the transfer of a daughter.
Look at what stands at the centre of each story: a dead ram, a dead deer, a marriage. The son must continue the line; the daughter is given away. In both cases, the child enters the adult world on terms it does not really choose. This is the real sacrifice. It does not happen on the altar; it happens before, when the child’s life and reproduction are placed in the service of the parents. The stories, covertly but eloquently, are telling us that children are livestock.
An Ancestral Practice
These myths did not come from nowhere. In the distant past, the eating of children was simply part of the eating of bodies: at Atapuerca, some 800,000 years ago, another human species defleshed and consumed its young alongside its game, and at Gough’s Cave our own species was still doing the same fifteen thousand years ago.
Closer to us, the treatment becomes recognisable — and recognisably sacrificial. At Knossos, the bones of children were found defleshed with the same fine cuts used on slaughtered animals, and mixed with the bones of sheep. Excavations on Mount Lykaion found a 3,000-year-old teenager buried in the heart of a massive ash altar, among the remains of a millennium of animal sacrifice — on the very mountain where legend said a king served the gods a child’s flesh mixed in with the meat of the animals. And in the biblical lands themselves, the practice had a place and a name — the Topheth, in the valley of Ben-Hinnom — where, as God laments through Jeremiah (7:31), the people burned their sons and daughters in the fire. Similar institutions existed in Carthage or, further away, among the Mexica and the Incas.
As orally transmitted myths, the stories of Isaac and Iphigenia draw from these practices. What matters is the awareness they reflect: the passage from a bloody sacrifice to a dramatized, mythical representation, and finally to symbolic or sublimated forms. Stories like these represent a stage in our species’ moral evolution: the transition from the acceptance of human sacrifice to the cultural search for ways to process its ethical weight.
The Greeks named half their world after a child who was cooked and served: the Peloponnese is the island of Pelops, butchered by his father Tantalus and set before the gods. From Pelops descends the house of Atreus, and from Atreus, Agamemnon himself. This process culminates, within the Abrahamic tradition, with the figure of Jesus Christ, who not only embodies the son destined for sacrifice but voluntarily embraces that fate.
Jesus is like a new Isaac, but one who walks of his own will to the altar — the Lamb of God, the substitute animal now indistinguishable from the son it once replaced. Jesus takes the sublimation of sacrifice to its symbolic extreme, offering his own flesh and blood to others so that they might quite literally feed on him. It is almost sarcastic: the son becomes not only the food but also the feeder, livestock that farms itself. His shepherds keep the imagery alive to this day: the priest is a pastor, and the congregation his flock.
The Child as a Domesticated Animal
Many thinkers have puzzled over this seemingly aberrant practice, but from my point of view, it is entirely understandable. In previous entries on this blog (beginning here), I have proposed that the human species arose through intentional self-domestication. This is no mere pastoral metaphor: just as we domesticate animals and plants to gain their cooperation and productivity, we have applied the same logic to our ourselves. Domestication means control: control of reproduction, of growth, of autonomy, and of life itself.
As with non-human animals, this implies a profound emotional ambivalence. We “love” our children as we love our pets: sometimes for what they really are, sometimes for what we want them to be. Through this bond we have cooperated and built the rich and beautiful world we inhabit, but also competed to spread our seed, like Sarah and Hagar. The child thus becomes a living resource, valued yet subordinated, serving the continuity of a lineage.
It is no coincidence that the great narratives of child sacrifice arose among societies that raise and slaughter animals. As agricultural peoples learned to breed and cull their herds, they could recognise that their own children were being reared under similar principles. The tales of Isaac, Iphigenia, and Jesus are not mere legends or poetic metaphors: they are the direct expression of a real, structural tension within our species.
