Around 4000 b.c., a man heaves a jagged field stone downward into flesh. The arid wind strips moisture from the soil outside the Cave of Treasures. Daily survival requires brutal manual labor. Tilling the unforgiving earth leaves hands blistered and muscles raw. A suffocating dread grips the landscape. Death arrives suddenly in the open field. The Father of Compassion later offers quiet comfort to the shattered parents.
Cain murders Abel in a sudden fit of rage. The elder brother brings twenty pounds of withered crops to the stone altar. The younger brother slaughters one fat sheep. The Creator accepts the animal sacrifice. The Almighty rejects the rotting grain. Jealousy breaks the bonds of the first family. Cain ambushes Abel away from the safety of their parents. The farmer strikes his brother with a heavy rock. The blow cracks bone. Later Ethiopic and Arabic pseudepigraphal traditions note the dispute involved earthly marriages. Gentile traditions also point to this moment as the historical birth of human warfare. The Father of All watches his creations fail.
The weapon is a mundane object of primitive farming. It is a simple rock pulled directly from the dirt. This transforms an everyday obstacle of agriculture into a permanent instrument of destruction. Violence requires no specialized craft. It only requires proximity and unrestrained anger.
A rough tool swung in anger builds nothing but a grave.
Blood dried into the soil beneath the open sky. A rough cairn marked a permanent change in the mortal landscape.
