At one time the Horse had the plain entirely to himself. Then a Stag intruded into his domain and shared his pasture. The Horse, desiring to revenge himself on the stranger, asked a man if he were willing to help him in punishing the Stag. The man replied that if the Horse would receive a bit in his mouth and agree to carry him, he would contrive effective weapons against the Stag. The Horse consented and allowed the man to mount him. From that hour he found that instead of obtaining revenge on the Stag, he had enslaved himself to the service of man.

Aesop was an ancient Greek storyteller, believed to have lived around 620–564 BCE, whose fables have been retold and preserved across millennia. "The Horse and the Stag" is one of his most pointed moral tales, warning that surrendering freedom in the name of revenge can cost far more than whatever wrong was first suffered.
