In Roman Egypt, Greek remained the language of rule but the introduction of the Roman legal system and practices resulted in changes within the bureaucracy and an increase in documentation. Declarations were now required for birth, death, taxes, and much else. There were minor changes in the vocabulary of slavery, but in terms of acquisition and use much remained unchanged. There was an active market in slaves who were primarily employed in the home. There is further evidence for slaves in labouring jobs, artisanal roles, in entertainment and sex work. Imperial slaves held some important administrative roles, and slaves might act as business agents in urban settings. Slave labour was little used in agriculture, though the balance between free and unfree changed over time. As earlier, the boundaries between these categories were sometimes blurred. There is evidence, too, for the manumission of slaves. Documents translated in this chapter illustrate the situation.
