The history of the human race suggests that master position-holders always wanted some form of identification of their slaves. The slave’s name and family links were not adequate. Galley slaves had the letters GAL burnt into their arms. In imperial Russia the Katorshniki (public slaves) were branded in a grisly manner – the letters KAT being punctured on their cheeks and forehead; and gunpowder rubbed into their wounds. In several countries, slaves had their heads shorn, except for a pigtail from the crown. The shorn head was symbolic of castration, loss of manliness, power and freedom. Slavery is one of the most extreme forms of the relation of domination approaching the limits of total power from the view point of the master and the total powerlessness from the view point of the slave. All power strives for authority.
