The ancient Egyptians used to mark their livestock with unique fire-brand symbols representing their owners. It was probably the Romans who first extended the practice in a structured way to the marking of the bodies of human slaves. Thus the slave could be easily identified and registered in inventories of property, and bought and sold between owners as an identifiable object of greater or lesser value, according to its pedigree. In the same way, the permanent branding by hot iron of a male slave by his Mistress has become the most powerful expression of Her total ownership of him. Of course I keep all My male slaves locked in permanent chastity under My absolute control.
