On the day before Christmas, 1170, Robert de Broc, member of a family of royal servants that had taken up King Henry II's fierce opposition to Thomas Becket, seized a horse bringing goods to the archbishop and cut off its tail. The next day, Archbishop Thomas noted this incident after his Christmas sermon when renewing his excommunication of Robert and several others, and he discussed it again four days later in his initial meeting with the men who would shortly murder (...) him. The excision of the horse's tail appears in five of the biographies of the martyr and subsequently in the national chronicles of Roger of Howden and Ralph of Diceto. Why did a minor act of cruelty inflicted on a horse seem so noteworthy to contemporaries? The sources recording it resound with the rich Latin vocabulary of shame: “dedecus, contemptus, ignominia, dehonestatio, opprobrium.” Robert's highly symbolic act, part of a pattern of harassment by the Brocs, was designed not just to threaten Becket but also to humiliate him.
