This chapter introduces slavery during the three centuries of Ptolemaic rule in Egypt for which papyri, recycled in mummy casing or discovered archived together, provide a wealth of texts in both Greek and Egyptian Demotic. Greek settlers brought a developed form of slavery to Egypt. Traditional forms of dependence, however, continued in domestic as in temple contexts, where sacred slaves were dedicated to a god. The terminology of slavery is scrutinised and Greek city law codes examined for information on slaves. The third-century BC archive of Zenon provides many details on where slaves came from and how they were acquired. Slaves are mainly found in a domestic context but there is some evidence for workshop employment, especially in textiles; evidence for their use in agriculture is minimal. To gain their freedom slaves might benefit from testamentary grants but running away was the more usual method.
